    “>TC 70S-2 093 Washington Alloy .035, 33 Lb. 70S-2 MIG Wire, Pack of (1)

    Washington Alloy TC 70S-2 093 is a .035 in (0.9 mm) ER70S-2 solid MIG wire on a 33 lb (15 kg) spool. For buyers and support teams, the main question is not whether the wire can weld mild steel—it can—but whether it matches the job’s fit-up, base-metal condition, and feeder setup. This article breaks down where this wire fits, what to verify before use, and how to troubleshoot common feeding and weld-quality issues without guessing at specifications that are not documented here.

    Key Takeaways

    • ER70S-2 is a solid MIG wire used for mild-steel fabrication, maintenance, and repair.
    • The .035 in diameter is a common general-purpose size, but final selection depends on procedure, material thickness, and wire-feed setup.
    • This product is described as triple-deoxidized with Al/Ti/Zr chemistry, which is intended to help when base metal has light mill scale or minor surface contamination.
    • The listing indicates a 33 lb spool and pack of one.
    • If your process, joint design, or code requirement is uncertain, verify the WPS, wire classification, and machine settings before welding.

    What This Wire Is For

    As listed, TC 70S-2 093 is aimed at mild-steel work in fabrication, maintenance, and repair. That makes it relevant for shops that need a practical solid wire for general production work and field repair where clean surface prep is not always perfect. The ER70S-2 classification is commonly used when a shop wants a wire that tolerates light oxidation better than a basic clean-steel setup.

    Do not assume this wire is the right answer for every joint. A MIG wire selection still depends on base metal chemistry, joint design, shielding gas, transfer mode, and the required mechanical properties of the finished weld. If any of those points are unclear, treat this product as a candidate, not a final approval.

    Inspect Before You Load the Spool

    Before installing the spool, do a basic receiving check.

    • Check the spool label against the purchase record. Confirm the product title and ER70S-2 classification.
    • Inspect the wire surface for visible rust, oil, kinks, or loose winding.
    • Verify the spool fits the feeder without forcing the hub or retainer.
    • Inspect the drive rolls, inlet guide, liner, and contact tip for wear or debris before loading the wire.
    • Verify the shielding gas, polarity, and wire-feed settings are correct for the procedure being used.

    If the shop has recurring feed issues, the wire is not the first thing to blame. Check the feeder path, tension, liner condition, and tip wear before changing consumables again.

    Troubleshooting Support: What to Check First

    Problem: Erratic feeding or birdnesting

    • Check drive-roll pressure. Too much pressure can deform the wire; too little can slip.
    • Inspect the liner for wear, contamination, or tight bends in the gun cable.
    • Verify the contact tip size matches the wire diameter. If unsure, use Unknown (Verify) until the correct tip is confirmed.
    • Check the wire path from spool to gun for sharp drag points.

    Problem: Excess spatter or unstable arc

    • Inspect shielding gas flow and nozzle condition.
    • Verify voltage and wire-feed speed against the procedure or WPS.
    • Check that the work clamp has solid contact and the joint is clean enough for the process.
    • Inspect for contamination such as paint, oil, or heavy scale.

    Problem: Porosity in the weld bead

    • Verify gas coverage at the nozzle and around the joint.
    • Check for drafts, leaks, or a damaged gas hose.
    • Inspect the base metal surface and remove moisture, oil, and heavy rust before welding.
    • Verify the filler wire is not contaminated from poor storage.

    Selection Support: Where to Confirm the Filler Metal

    If your team needs a starting point for filler selection or cross-checking wire classifications, use the WSP resources as reference tools rather than automatic approvals. When available, the filler metal finder should be treated as a selection starting point, not a guarantee that a procedure is approved for your job, code, or base metal combination.

    Use those pages to narrow down options, then verify the actual WPS, shielding gas, and wire classification before production use.

    Product and Parts Notes

    This listing is for one spool of Washington Alloy TC 70S-2 093. The documented size is .035 in and the documented spool weight is 33 lb. Beyond that, do not assume details such as drive-roll type, recommended gas mix, or exact machine compatibility unless your internal procedure sheet or manufacturer documentation confirms them. For uncertain technical details, mark them as Unknown (Verify).

    For buyers, the important points are simple: confirm the classification, confirm the diameter, confirm the spool weight, and confirm that the feeder setup matches the wire path requirements of your machine. If the wire is being purchased for a repair bay, make sure the operators know whether the work is light fabrication, maintenance welding, or a qualified procedure with tighter limits.

    Practical Use Notes

    Triple-deoxidized ER70S-2 wires are often chosen when the surface is not ideal, but that does not eliminate prep. Remove loose scale, paint, oil, moisture, and heavy corrosion whenever possible. The more contaminated the joint, the less likely any MIG wire will produce reliable results. The right response is better cleaning, not overreliance on filler metal chemistry.

    For shop support teams, the right workflow is: identify the base metal, confirm the required process, match the filler classification, and verify the feeder hardware. This wire may be a good general-purpose option, but the procedure still controls the final weld.

    Safety Notes

    • Use proper PPE for MIG welding, including eye, face, hand, and body protection.
    • Keep the work area ventilated and control fumes at the source when possible.
    • Do not weld on coated or unknown materials until hazards are identified.
    • De-energize equipment before servicing the feeder, liner, or gun components.
    • Store wire clean and dry to reduce contamination risk.

    FAQ

    Is TC 70S-2 093 suitable for mild steel?
    Yes, the listed application is mild-steel fabrication, maintenance, and repair. Final suitability still depends on the WPS and job requirements.

    Can I use this wire on material with light mill scale?
    The product description says the triple-deoxidized ER70S-2 chemistry is suited for light mill scale or minor surface contamination. That is helpful, but it is not a substitute for proper cleaning.

    Does .035 in wire work in every MIG machine?
    No. Wire diameter compatibility depends on the feeder, drive rolls, liner, contact tip, and procedure. Verify the setup before loading the spool.

    Is the shielding gas confirmed in the product listing?
    Unknown (Verify). The available product information does not document a specific gas requirement.

    “>TC 70S-2 104 Washington Alloy .035, 44 Lb. 70S-2 MIG Wire, Pack of (1)

    TC 70S-2 104 Washington Alloy .035, 44 Lb. 70S-2 MIG Wire, Pack of (1) is a solid MIG wire intended for mild-steel fabrication, maintenance, and repair. The key points for buyers are straightforward: it is .035 in (0.9 mm) diameter, it is an ER70S-2 class wire, and it is supplied on a 44 lb (20 kg) spool. For welders and maintenance teams, the practical question is not just what the label says, but whether the wire fits the feeder, matches the job, and gives stable performance in the actual work environment.

    This breakdown focuses on what to check before purchase and what to inspect after the spool arrives. It does not assume machine settings, procedure approval, or certification details that are not stated on the product page. Where a detail is not confirmed in the provided source, it is marked as Unknown (Verify).

    Key Takeaways

    • TC 70S-2 104 is listed as a .035 in solid MIG wire for mild steel work.
    • The spool size is 44 lb (20 kg), which matters for feeder capacity and shop consumption rate.
    • ER70S-2 chemistry is commonly used when welders want a wire that can handle light mill scale or minor surface contamination better than basic clean-steel wire, but the actual base-metal condition still needs inspection.
    • Do not assume machine compatibility, polarity, shielding gas, or WPS approval from the product name alone. Verify those items against your equipment and procedure.

    What the Product Is Used For

    Based on the supplied product information, this wire is aimed at mild-steel fabrication, maintenance, and repair. That makes it relevant to production shops, farm and fleet repair, structural maintenance, and general fabrication work where a solid wire is preferred over flux-cored wire. The triple-deoxidized ER70S-2 chemistry is positioned for cleaner welds on steel that may have light mill scale or minor contamination. That does not remove the need for cleaning, but it may provide a wider practical window than a basic wire on less-than-perfect material.

    For buyer guidance, the first decision is whether your work is actually mild steel. If the job is stainless, aluminum, hardfacing, or a specialty alloy, this is not the right starting point. If the job is carbon steel and the feeder can handle .035 wire, it becomes a reasonable candidate for evaluation.

    Check Before You Buy

    • Check wire diameter: Confirm your feeder, drive rolls, contact tips, and gun setup are intended for .035 in wire.
    • Inspect spool capacity: Verify your feeder can physically accept a 44 lb spool. Some machines need an adapter or a different hub. Unknown (Verify).
    • Verify base metal: Confirm the job is mild steel or compatible carbon steel work.
    • Inspect the weld procedure: If you run controlled fabrication or repair work, verify the wire is allowed under your WPS or internal procedure before use.
    • Check shielding gas and polarity: Do not assume from the product name. Verify with your procedure and machine setup. Unknown (Verify).

    Troubleshooting and Support: What to Inspect if Feeding or Arc Stability Is Poor

    If the wire arrives and the arc is unstable, do not immediately blame the filler metal. Run a basic inspection sequence.

    • Inspect the drive system: Check drive-roll size, groove type, tension, and liner condition.
    • Check the contact tip: A worn or oversized tip can cause erratic feeding and arc wander.
    • Verify spool installation: Make sure the spool turns freely and is not over-tightened on the hub.
    • Inspect the gun cable: Look for kinks, tight bends, or internal liner wear.
    • Confirm wire cleanliness: If the wire has contamination, rust, or packaging damage, document it before use.

    If porosity appears, inspect the work surface, shielding gas flow, leaks in the gas path, and joint prep before changing wire type. If lack of fusion appears, verify voltage, travel speed, and joint prep. If burnback or birdnesting shows up, inspect wire feed tension, tip size, and liner friction first.

    WSP Lookup and Filler Metal Finder

    Use the Weld Support Parts lookup tools as selection starting points, not guaranteed procedure approvals. They help narrow options, but they do not replace a qualified WPS, procedure test, or equipment verification.

    WSP lookup page

    WSP filler metal finder page

    If your team uses filler metal search tools, compare the wire class, diameter, and intended base metal against your actual job. Then verify the final choice against machine limits, spool size limits, and procedure requirements.

    Product / Parts Review

    The listing provided for this article identifies TC 70S-2 104 Washington Alloy .035, 44 Lb. 70S-2 MIG Wire, Pack of (1). The confirmed details are limited to the wire class, diameter, spool weight, and pack quantity. Other technical details such as country of origin, AWS approval language beyond the ER70S-2 class designation, exact gas recommendation, and machine compatibility are Unknown (Verify).

    For maintenance buyers, the main value of a large spool is reduced changeover time. For production or repair work, that can help reduce interruptions. The tradeoff is storage and handling. A 44 lb spool needs a feeder and shop process that can manage the larger package without feed problems.

    If you are comparing this wire against another ER70S-2 option, evaluate the following: feeder fit, spool size fit, workpiece condition, and your normal gas and procedure setup. Do not compare only on price or spool weight. Those alone do not tell you whether the wire will run well in your machine.

    Safety Notes

    • Follow your welding procedure, machine manual, and shop safety rules.
    • Verify ventilation and fume control before welding carbon steel.
    • Inspect the work area for fire hazards, especially during maintenance and repair work.
    • Use proper PPE for arc flash, spatter, and handling the spool.
    • Do not rely on product labeling alone for procedure approval or machine setup.

    “>TC 70S-2 16 Washington Alloy .045, 11 Lb. 70S-2 MIG Wire, Pack of (1)

    Washington Alloy TC 70S-2 16 is a solid MIG wire in .045 in. diameter on an 11 lb spool. The core value of this wire is straightforward: it is intended for mild-steel fabrication, maintenance, and repair where stable feeding and practical arc control matter more than marketing claims. The ER70S-2 classification is typically used for cleaner welds on steel with light mill scale or minor surface contamination, but it is not a substitute for proper joint prep. Always verify the base metal condition and welding procedure before use.

    Key Takeaways

    What This Wire Is For

    This product is positioned for general mild-steel MIG welding in fabrication and maintenance environments. The triple-deoxidized ER70S-2 chemistry is commonly used to tolerate light surface oxidation better than basic solid wires, but the practical result depends on current settings, gas coverage, and operator technique. Use it as a production filler wire when the weldment calls for solid wire MIG on steel and the setup is already aligned to .045 in wire.

    If you are comparing options for steel filler metal selection, a filler metal finder can help you narrow down the starting point. It does not replace the welding procedure or a code requirement. Use the WSP filler metal finder as a selection reference only, then verify the final match against the application requirements.

    Setup Checks Before You Load the Spool

    Check: Confirm the machine is configured for .045 in solid wire. Verify drive rolls, gun liner, and contact tip size are appropriate for the wire diameter. Unknown (Verify) if the existing setup was previously used for a different diameter.

    Inspect: Look at the spool wrap, wire surface, and feed path. Any kinks, corrosion, or contamination can cause feed irregularity and arc instability.

    Verify: Confirm shielding gas type and flow are correct for the procedure. The product details provided here do not state a gas requirement, so use Unknown (Verify) and follow the approved WPS or shop standard.

    Check: Make sure the polarity matches solid MIG wire requirements for your process. If polarity is not confirmed by procedure or machine label, treat it as Unknown (Verify).

    Inspect: Clean the work lead connection, gun neck, liner entrance, and drive rolls. Small restrictions in the feed path often show up as birdnesting or erratic burnback.

    Verify: Test feed on scrap before going to production. A short trial pass is faster than correcting a bad setup on the part.

    Troubleshooting and Support

    If the wire feeds poorly

    Check drive roll tension first. Too much pressure flattens the wire and increases drag; too little lets the rolls slip. Inspect the liner for wear, contamination, or incorrect size. Verify that the contact tip is not oversized or worn out. If the wire was stored in a humid area, inspect it for surface oxidation before loading.

    If the arc is unstable

    Inspect the contact tip, nozzle, and work clamp. Verify consistent stickout and travel speed. If the arc wanders after a spool change, confirm the wire is seated correctly in the feeder and that the gun cable is not sharply bent.

    If weld quality is inconsistent

    Check base-metal prep before changing machine settings. ER70S-2 can help with light contamination, but it cannot compensate for heavy rust, paint, oil, or poor joint alignment. Verify fit-up, cleaning method, and shielding coverage before assuming the wire is the problem.

    For surface prep support, the Weld Support Parts blog includes a wire-wheel and pen-brush article that can help with cleaning strategy: Rocaris 6 Pack Wire Wheel & Pen Brush Set: Carbon Steel for Weld Cleaning & Surface Prep. Use it as a cleaning reference, not a process approval.

    Safety Notes

    FAQ

    Is this wire only for mild steel?

    The confirmed product information identifies it as ER70S-2 solid MIG wire for mild-steel fabrication, maintenance, and repair. Use on other metals is Unknown (Verify) unless your procedure specifically approves it.

    Can I use this wire on rusty or dirty material?

    ER70S-2 is often selected when there is light mill scale or minor surface contamination, but heavy rust, oil, paint, or poor joint prep still need removal. Inspect the base metal and verify cleaning requirements first.

    What machine settings should I use?

    Unknown (Verify). Machine settings depend on the welding procedure, material thickness, transfer mode, shielding gas, and joint design. Start from the approved WPS or manufacturer guidance, then verify on scrap.

    Will an 11 lb spool fit my feeder?

    Unknown (Verify). Spool size and hub compatibility vary by machine and feeder design. Check the feeder documentation and compare it with the spool dimensions and adapter requirements before purchasing.

  • ER80S-D2 MIG / GMAW Filler Metal: Filler Metal Finder Notes

    ER80S-D2 MIG / GMAW Filler Metal: Filler Metal Finder Notes

    ER80S-D2 MIG / GMAW Filler Metal

    ER80S-D2 MIG / GMAW filler metal is a low-alloy wire used where the weld deposit needs higher tensile strength and added molybdenum compared with general-purpose mild steel wires. It is typically considered for high-strength carbon and low-alloy steels, but it should not be treated as a default choice. The correct wire depends on the WPS, base metal, service conditions, joint design, shielding gas, and required mechanical properties.

    Use the WSP filler metal page as a starting point, not as a procedure approval. Confirm the classification, base metal, and service requirements before ordering wire or welding production parts.

    Key Takeaways

    • ER80S-D2 is a classification, not a blanket approval for all low-alloy jobs.
    • Confirm the WPS and code requirements first.
    • Verify the base metal grade and thickness range before selection.
    • Check shielding gas requirements and procedure parameters against the manufacturer data sheet.
    • When details are uncertain, mark them as Unknown (Verify) and stop before production welding.

    How to Use the Filler Metal Finder Page

    The Weld Support Parts filler metal finder page is useful when you are narrowing down a starting point for wire selection. It is not a substitute for code compliance or a qualified WPS. Use the page to compare the listed classification, process, and base material family, then move to the manufacturer data sheet and your internal welding documentation.

    Open the filler metal finder page and confirm these items:

    • Process: MIG / GMAW
    • Classification: ER80S-D2
    • AWS spec: AWS A5.28
    • Base material family: High-strength carbon and low-alloy steels

    If your application does not match those basic categories, do not assume the wire is suitable. Verify the actual specification or use a different filler metal family.

    Selection Checks Before Ordering

    Follow a short check-inspect-verify sequence before you place an order.

    • Check: The WPS for the required filler classification.
    • Inspect: The base metal identification on drawings, material certs, or job travelers.
    • Verify: The service condition. If the part sees elevated stress, impact loading, fatigue, or temperature exposure, review the weld metal requirements carefully.
    • Check: Shielding gas type and transfer mode requirements in the procedure.
    • Inspect: Wire diameter and spool size requirements. The listed sizes for this product family may include .030 in, .035 in, and .045 in, but confirm the exact size on the product page and data sheet before purchase.
    • Verify: The manufacturer name and data sheet for the exact wire you intend to use.

    If any item is missing, the correct action is not to guess. Mark the unknown detail as Unknown (Verify) and stop until the documentation is complete.

    Troubleshooting Common Selection Problems

    Problem: The wire classification looks right, but the job still fails review

    Check: Whether the WPS actually allows ER80S-D2 for that joint and base metal combination.

    Inspect: Any project-specific customer requirements, postweld heat treatment requirements, or impact testing requirements.

    Verify: Whether a different filler classification is required by code or contract. If the answer is unknown, treat it as Unknown (Verify) and route it to welding engineering or QA.

    Problem: The base metal is low-alloy, but the exact grade is not confirmed

    Check: Heat numbers, mill certs, or material markings.

    Inspect: Whether the material is actually carbon steel, HSLA, or another alloy family.

    Verify: The grade before using ER80S-D2 as a selection baseline. A general family match is not enough for production release.

    Problem: The filler metal finder page gives a starting point, but no final answer

    Check: The page description and classification fields.

    Inspect: The manufacturer data sheet for the specific wire brand.

    Verify: Procedure approval through your WPS, PQR, or responsible welding authority. Finder pages are support tools, not approval documents.

    Practical Purchasing Notes

    When buying ER80S-D2 wire, keep the ordering record tied to the actual job requirements. Do not order only from memory or from a past job that happened to use a similar classification.

    • Record the WPS number or internal reference.
    • Record the base metal grade and thickness.
    • Record the required wire diameter.
    • Record the shielding gas from the approved procedure.
    • Record the manufacturer and data sheet revision, if known. If unknown, mark Unknown (Verify).

    This avoids mix-ups between similar low-alloy wires and helps maintenance buyers prevent nonconforming stock from reaching the floor.

    Safety Notes

    • Do not weld from a filler metal description alone.
    • Review the WPS, SDS, and manufacturer data sheet before use.
    • Use proper ventilation and fume control for GMAW welding.
    • Verify storage condition and spool handling before loading wire.
    • If the job has critical service requirements, involve welding engineering or QA before starting production.

    FAQ

    Is ER80S-D2 a direct replacement for ER70S-2?

    No. They are not interchangeable by assumption. ER80S-D2 is a low-alloy wire with different intended mechanical property behavior. Check the WPS and verify the required classification before substituting anything.

    Can I use ER80S-D2 on any low-alloy steel?

    No. Base metal family alone is not enough. Inspect the exact grade and service condition, then verify that the procedure permits this wire.

    What should I do if the wire size is not listed in my internal notes?

    Check the product page and manufacturer data sheet. If the size still cannot be confirmed, treat it as Unknown (Verify) and do not order until confirmed.

    Is the filler metal finder page a final approval source?

    No. It is a starting point for selection only. Verify against the WPS, code requirements, and manufacturer documentation.

    Sources Checked

    Final note: ER80S-D2 is a useful starting point for higher-strength carbon and low-alloy welds, but the correct answer still comes from the procedure and the material documentation. Check the facts, inspect the material, and verify the approval path before welding.

    Product not found.
    “>Stoody 965-G, Hard Facing MIG Wire, .045 X 33 lb Basket

    Stoody 965-G, Hard Facing MIG Wire, .045 X 33 lb Basket is positioned as a general-purpose hardfacing filler for maintenance and repair work. The practical value of a hardfacing wire is not just depositing metal. It is about matching the wear mechanism, the base metal, and the repair sequence so the rebuilt surface lasts long enough to justify the labor. For shops and field teams, that means checking the parent metal, the wear pattern, and the machine setup before any arc starts.

    Key Takeaways

    What this wire is for

    Hardfacing wire is used when the goal is to slow down wear, not to restore cosmetic appearance. Stoody 965-G is described as a general-purpose option that balances impact resistance and abrasion resistance. In practical terms, that makes it a candidate for rebuilding edges, contact surfaces, and high-wear zones where parts see repeated loading, scraping, or sliding. The important point is that hardfacing is application-specific. A wire that works well on one wear pattern may fail early on another.

    Before selecting any hardfacing consumable, identify the dominant wear mode:

    If the wear mode is mixed, a general-purpose product may be reasonable. If the part is subject to a very specific wear pattern, verify the deposit properties before committing to a full rebuild.

    Product and parts check

    The available product data identifies the item as Stoody 965-G, Hard Facing MIG Wire, .045 x 33 lb Basket. Beyond that, the technical details provided are limited. Do not assume machine settings, shielding gas, or deposition behavior from the product name alone.

    For purchasing teams, the main part check is whether the wire format matches the feeder and drive system in service. Basket wire can be handled differently than spool wire. Verify the feeder setup, liner condition, and drive-roll suitability before loading the wire into production equipment.

    Check, inspect, verify before welding

    Check the component for the actual wear profile. Measure where material loss occurred and note whether the damage is shallow, gouged, peened, or cracked. If the part has cracking, distortion, or prior overlays, hardfacing may require repair sequencing first.

    Inspect the base metal condition. Remove scale, grease, paint, and embedded contamination. On manganese steel and other work-hardening materials, verify the surface is prepared in a way that supports sound fusion without creating unnecessary heat buildup. Confirm that the part can tolerate the thermal load of the repair process.

    Verify equipment setup before use:

    Unknown (Verify): the specific voltage and wire-feed starting points for this product. Use published manufacturer guidance for the exact lot and machine combination.

    Troubleshooting support

    Problem: poor arc stability. Check for inconsistent wire feed, worn liner, damaged contact tip, or incorrect drive-roll pressure. Verify the wire path is not contaminated and that the feeder is not slipping on the basket wire.

    Problem: excessive spatter or rough bead shape. Inspect shielding gas flow, nozzle condition, CTWD consistency, and travel speed. Verify the machine settings against the manufacturer data. If the bead profile changes after a few inches, look for feed variation first.

    Problem: premature cracking or edge loss. Check whether the deposit was applied to a surface that needed preheat, interpass control, or a different hardfacing strategy. Verify the wear mode. A deposit that is too hard or too brittle for the service condition can fail early.

    Problem: wire feeding issues in a production cell. Inspect the basket setup, drive-roll wear, contact tip diameter, and liner length. Verify there is no birdnesting, twist, or drag in the cable. For maintenance buyers, feeder compatibility should be confirmed before the wire is stocked in quantity.

    Safety notes

    Buying and application notes

    If the goal is stocking a maintenance consumable for recurring wear jobs, this product fits the category of general-purpose hardfacing wire. That does not make it universal. For the best result, match the consumable to the part family, service environment, and feeder hardware. If the job is on carbon steel, low-alloy steel, or manganese steel, the source description suggests this product may be relevant. If the substrate is outside those materials, verify suitability before use.

    For teams standardizing consumables, document three items in the job packet: the base metal, the wear mode, and the verified machine settings. That reduces trial-and-error and helps avoid scrap on high-value parts.

  • Why Your MIG Weld Has Porosity (and How to Fix It Fast)

    Porosity in MIG welding shows up as pinholes or small voids in the weld bead. It weakens the weld and usually points to shielding gas failure or contamination. This guide breaks down the exact causes and the fastest way to fix it using proper setup and wire selection.

    Key Takeaways

    • Porosity is caused by poor shielding gas coverage or contamination
    • Dirty metal and bad wire are the most common causes
    • Gas flow, nozzle condition, and wire choice fix most issues
    • ER70S-6 wire helps reduce porosity on less clean steel

    What Causes MIG Weld Porosity

    Porosity occurs when atmospheric gases get trapped in the weld pool as it solidifies. In MIG welding, shielding gas is supposed to prevent this. When coverage fails, defects form.

    • Low shielding gas flow
    • Wind or airflow disrupting gas
    • Dirty or oily metal
    • Rusty or contaminated wire
    • Improper stickout or angle
    • Clogged nozzle or diffuser

    How to Fix MIG Porosity

    • Set gas flow to 20–30 CFH (verify for your setup)
    • Keep stickout around 3/8”–1/2”
    • Clean metal to bare steel
    • Check for gas leaks
    • Replace worn nozzle or diffuser
    • Switch to ER70S-6 wire if needed

    MIG Welding Wire Selection Guide 2025 | ER70S-6 vs ER70S-3 Specs

    MIG wire selection affects weld quality, spatter levels, and penetration depth. Choosing the right wire depends on base metal composition, surface condition, and shielding gas—not just diameter and tensile strength.

    Common MIG Wire Classifications

    ER70S-6 (Most Common)

    • Deoxidizers: Manganese, silicon
    • Tensile strength: 70,000 PSI minimum
    • Best for: Dirty or rusty steel, single-pass welds, general fabrication
    • Shielding gas: 75/25 Ar/CO₂ or 100% CO₂
    • Spatter level: Moderate

    ER70S-3

    • Deoxidizers: Lower manganese and silicon than ER70S-6
    • Tensile strength: 70,000 PSI minimum
    • Best for: Clean steel, multi-pass welds, automotive sheet metal
    • Shielding gas: 75/25 Ar/CO₂ (100% CO₂ not recommended)
    • Spatter level: Low

    ER308L (Stainless Steel)

    • Composition: 19-21% chromium, 9-11% nickel
    • Best for: 304/304L stainless steel
    • Shielding gas: 90/10 Ar/CO₂ or tri-mix (He/Ar/CO₂)
    • Corrosion resistance: Excellent

    ER316L (Stainless Steel)

    • Composition: 18-20% chromium, 11-14% nickel, 2-3% molybdenum
    • Best for: 316/316L stainless, marine environments, chemical processing
    • Shielding gas: 90/10 Ar/CO₂ or tri-mix
    • Corrosion resistance: Superior (molybdenum addition)

    Wire Diameter Selection

    DiameterAmperage RangeMaterial ThicknessTypical Use
    0.023”30-130A24-18 gaugeAutomotive sheet metal, thin tubing
    0.030”40-145A18-14 gaugeGeneral fabrication, light structural
    0.035”50-180A14 gauge-1/4”Most common all-purpose size
    0.045”75-250A1/4”-1/2”Heavy structural, thick plate
    0.052”100-300A1/2”+Industrial fabrication, heavy equipment

    Rule of thumb: Thinner wire = better control on thin material. Thicker wire = faster deposition on heavy plate.

    Shielding Gas Impact on Wire Performance

    75/25 Argon/CO₂ (C25)

    • Pros: Low spatter, smooth arc, good bead appearance
    • Cons: Higher cost than 100% CO₂
    • Best for: ER70S-3, ER70S-6, stainless steel

    100% CO₂

    • Pros: Deep penetration, low cost
    • Cons: Higher spatter, rougher arc
    • Best for: ER70S-6 on thick steel (not recommended for ER70S-3)

    90/10 Argon/CO₂

    • Pros: Minimal spatter, excellent for stainless
    • Cons: Shallow penetration on carbon steel
    • Best for: ER308L, ER316L stainless wire

    Wire Storage & Handling

    Moisture Contamination – Causes: Porosity, hydrogen cracking – Prevention: Store in sealed containers with desiccant packs – Shelf life: 12 months (carbon steel), 6 months (stainless)

    Wire Feed Issues – Kinked wire = erratic arc and bird-nesting – Solution: Use proper spool tension and liner size

    Liner Compatibility

    Wire DiameterLiner Inside Diameter
    0.023”-0.030”0.030”-0.035”
    0.035”0.035”-0.045”
    0.045”0.045”-0.052”
    0.052”0.052”-0.062”

    Oversized liner = wire wander. Undersized liner = excessive friction and burnback.

    Common Mistakes

    Using ER70S-3 on rusty steel
    Low deoxidizers can’t compensate for surface contamination. Result: porosity and weak welds. Use ER70S-6 or clean the base metal.

    Wrong liner size for wire diameter
    0.035” wire in 0.045” liner causes erratic feeding. Match liner to wire diameter within 0.005”-0.010”.

    Storing stainless wire without moisture protection
    Stainless wire absorbs moisture faster than carbon steel. Always use sealed containers with desiccant.
