• Welding Gloves Explained: MIG vs TIG vs Stick โ€” What Actually Matters

    Welding gloves look similar on the rack, but the wrong type will cost you control, comfort, or protection on the job. MIG, TIG, and Stick welding all place different demands on gloves. This guide breaks down the real differences so you can choose correctly and avoid common mistakes.

    Key Takeaways

    • TIG gloves prioritize dexterity over heat resistance
    • MIG gloves balance protection and flexibility
    • Stick welding requires maximum heat and spatter protection
    • Leather type, cuff length, and lining matter more than brand name

    Why Welding Gloves Are Process-Specific

    Each welding process produces different heat levels, arc duration, and spatter. Gloves are designed to manage these variables through leather thickness, stitching type, and insulation. Using the wrong glove usually results in poor control or premature glove failure.

    TIG Welding Gloves: Maximum Dexterity

    TIG welding requires fine torch and filler control. Gloves are typically thin, unlined, and made from goatskin or deerskin. Heat protection is limited and not suitable for heavy amperage or prolonged arc time.

    Best use cases:

    • Precision TIG work
    • Thin material
    • Bench or shop welding

    MIG Welding Gloves: Balanced Protection

    MIG gloves are thicker than TIG gloves and often lightly lined. They provide better spatter resistance while maintaining enough dexterity for gun control and part handling.

    Best use cases:

    • Fabrication and production MIG welding
    • Moderate amperage work
    • General shop use

    Stick Welding Gloves: Maximum Heat Resistance

    Stick welding produces the most heat and spatter. Gloves are heavily insulated with thicker cowhide or elk leather and extended cuffs. Dexterity is reduced, but protection is the priority.

    Best use cases:

    • High-amperage Stick welding
    • Structural and field work
    • Overhead or vertical welding

    Safety Notes (ANSI / AWS)

    • Welding gloves should meet ANSI Z49.1 requirements for protective equipment
    • Never substitute TIG gloves for high-heat Stick welding
    • Replace gloves immediately if holes or seam failures appear

    FAQ

    Can I use TIG gloves for MIG welding?
    Only for light MIG work. Spatter will quickly damage thin TIG gloves.

    Why do Stick gloves feel bulky?
    Extra insulation and thicker leather are required to handle higher heat and slag.

    What leather is best for welding gloves?
    Goatskin for dexterity, cowhide for durability, elk for maximum heat resistance.

    Do welding gloves expire?
    No, but leather degrades with heat, UV exposure, and moisture.

  • Auto-Darkening vs Passive Welding Helmets: Which Is Better for Your Work?

    Choosing the right welding helmet affects safety, productivity, and fatigue. Auto-darkening and passive helmets both protect your eyes, but they perform very differently in daily welding. This guide breaks down the real pros and cons so you can choose what fits your work.

    Key Takeaways

    • Auto-darkening helmets improve speed and consistency, especially for tack-heavy work
    • Passive helmets are simple, durable, and low-cost with zero electronics
    • Correct shade selection matters more than helmet price
    • Many welders keep both styles in the shop

    Auto-Darkening vs Passive Helmets

    Auto-darkening helmets switch from light to dark when the arc starts, allowing clear visibility during fit-up and positioning. Passive helmets use a fixed-shade lens and must be lowered before striking an arc.

    Pros and Cons of Auto-Darkening Helmets

    Auto-darkening helmets reduce neck strain, speed up workflow, and make tacking easier. Downsides include higher upfront cost and reliance on batteries or electronics.

    Pros and Cons of Passive Helmets

    Passive helmets are extremely reliable and inexpensive, but slow down work and increase the chance of missed starts or poor positioning.

    Which Helmet Is Right for You

    Production welding, fabrication, and TIG work benefit most from auto-darkening helmets. Stick welding outdoors, training environments, and backup use often favor passive helmets.

  • Plasma Cutter Buying Guide 2025 | Duty Cycle, Cut Capacity & Air Requirements

    Plasma cutters use ionized gas to cut conductive metals. Choosing the right cutter depends on material thickness, duty cycle, air supply, and cut quality requirementsโ€”not just amperage rating.

    Key Specifications Explained

    Amperage Rating & Cut Capacity

    AmperageRecommended CutMaximum CutTypical Material
    20-30A1/8โ€-3/16โ€1/4โ€Sheet metal, auto body, HVAC
    40-50A1/4โ€-3/8โ€1/2โ€Light fabrication, farm repair
    60-80A3/8โ€-1/2โ€3/4โ€General fabrication, structural steel
    85-100A1/2โ€-3/4โ€1โ€Heavy fabrication, thick plate

    Recommended cut = Clean cut with minimal dross (slag on bottom edge)
    Maximum cut = Severance cut (rough edge, heavy cleanup required)

    Rule of thumb: Buy 20-30% more amperage than your typical material thickness for clean cuts and longer consumable life.

    Duty Cycle

    Definition: Percentage of 10-minute period the machine can run at rated amperage before requiring cooldown.

    Duty CycleRuntime @ Max AmpsCooldownUse Case
    20%2 min8 minHobbyist, occasional use
    35%3.5 min6.5 minLight fabrication, DIY
    60%6 min4 minProduction shop, frequent use
    100%10 min0 minIndustrial, continuous operation

    Example: 50A cutter with 35% duty cycle can run 3.5 minutes at 50A, then must cool 6.5 minutes.
    At lower amperage: Duty cycle increases (50A cutter at 30A may have 60-80% duty cycle).

    Air Supply Requirements

    Compressed Air Specs:Pressure: 60-90 PSI (4-6 bar) – Flow rate: 4-8 CFM @ 90 PSI (varies by amperage) – Quality: Clean, dry, oil-free

    Compressor Sizing:

    Plasma AmperageMinimum CFM @ 90 PSIRecommended Tank Size
    20-30A4 CFM20 gallon
    40-50A5 CFM30 gallon
    60-80A6 CFM60 gallon
    85-100A8 CFM80 gallon

    Air quality issues: – Moisture = premature consumable failure and poor cut quality – Oil contamination = torch tip clogging – Solution: Install inline air dryer/filter between compressor and plasma cutter

    Input Power Requirements

    120V Plasma Cutters:Amperage range: 12-40A – Cut capacity: Up to 3/8โ€ recommended, 1/2โ€ maximum – Advantage: Portable, runs on standard outlets – Limitation: Lower duty cycle, reduced cut speed

    240V Plasma Cutters:Amperage range: 40-100A+ – Cut capacity: 1/2โ€-1โ€+ recommended – Advantage: Higher duty cycle, faster cutting, thicker material – Requirement: Dedicated 240V circuit (30-50A breaker)

    Dual Voltage (120V/240V): – Runs on both voltages with reduced performance on 120V – Example: 50A on 240V, 30A on 120V – Best for: Portable use + shop capability

    Cut Quality Factors

    Pilot Arc vs. Contact Start

    Pilot Arc (High-Frequency Start): – Arc initiates without touching workpiece – Pros: Cuts expanded metal, grating, rusty/painted steel – Cons: Higher cost, can interfere with electronics – Best for: Versatile cutting, field work

    Contact Start (Scratch Start): – Requires torch tip contact with workpiece to start arc – Pros: Lower cost, no electronic interference – Cons: Cannot cut expanded metal or start on edge – Best for: Budget cutters, clean flat plate

    Inverter vs. Transformer Technology

    Inverter-Based:Weight: 10-40 lbs (portable) – Efficiency: High (lower power consumption) – Duty cycle: Typically higher (35-60%) – Cost: Moderate to high – Best for: Modern shops, portability required

    Transformer-Based:Weight: 80-200 lbs (stationary) – Efficiency: Lower (higher power draw) – Duty cycle: Often 100% (industrial use) – Cost: Higher upfront, lower long-term maintenance – Best for: Heavy industrial, continuous operation

    Consumable Costs & Life

    Consumable Components

    PartFunctionTypical LifeCost per Set
    ElectrodeConducts current to arc1-3 hours cutting time$3-$8
    Nozzle (tip)Focuses plasma stream1-3 hours cutting time$2-$5
    Swirl ringStabilizes gas flow5-10 hours$1-$3
    Shield cupProtects nozzle10-20 hours$2-$5

    Consumable life factors: – Amperage setting (higher amps = shorter life) – Air quality (moisture/oil reduces life 50%+) – Arc-on time (duty cycle) – Proper technique (perpendicular torch angle, correct standoff)

    Annual consumable cost estimate: – Hobbyist (20 hours/year): $50-$100 – Light fabrication (100 hours/year): $250-$500 – Production shop (500+ hours/year): $1,500-$3,000

    Material Compatibility

    MaterialPlasma CutNotes
    Mild steelโœ“Best cut quality, minimal dross
    Stainless steelโœ“Clean cuts, some dross on thick sections
    Aluminumโœ“Requires higher amperage than steel (30% thicker capacity)
    Copperโœ“High thermal conductivity = slower cut speed
    Brassโœ“Similar to copper, produces toxic fumes (ventilation required)
    Cast ironโœ“Brittle, may crack from rapid heating
    Galvanized steelโœ“Toxic zinc fumes (ventilation mandatory)

    Cannot cut: Non-conductive materials (wood, plastic, concrete, glass)

    Torch Styles & Ergonomics

    Hand Torch (Standard)

    • Cable length: 10-25 feet
    • Weight: 1-3 lbs
    • Best for: Freehand cutting, portability
    • Limitation: Less precise than machine torch

    Machine Torch (CNC-Compatible)

    • Mounting: Designed for CNC table or track system
    • Standoff: Adjustable height control for consistent cut quality
    • Best for: Automated cutting, production runs
    • Cost: $200-$800 (in addition to hand torch)

    Ergonomic Features

    • Trigger lock: Reduces hand fatigue during long cuts
    • Swivel head: Prevents cable twist, improves maneuverability
    • Insulated grip: Protects from heat during extended use

    Common Mistakes

    Undersizing amperage for material thickness
    40A cutter on 1/2โ€ steel = slow, rough cuts and rapid consumable wear. Size cutter 20-30% above typical thickness for clean cuts.

    Using contaminated air supply
    Moisture and oil in compressed air destroy consumables in 10-20% of normal life. Always use inline air dryer/filter.

    Running at maximum amperage continuously
    Exceeds duty cycle, triggers thermal shutdown. Run at 70-80% of rated amperage for longer duty cycle and consumable life.

    Buying Checklist

    • โœ“ Amperage rating 20-30% above typical material thickness
    • โœ“ Duty cycle matches usage frequency (35%+ for regular use)
    • โœ“ Input voltage compatible with available power (120V or 240V)
    • โœ“ Pilot arc start for versatile cutting (expanded metal, rusty steel)
    • โœ“ Inverter technology for portability and efficiency
    • โœ“ Compressor meets CFM and PSI requirements
    • โœ“ Air dryer/filter included or purchased separately

  • 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 gasโ€”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/COโ‚‚ or 100% COโ‚‚
    • 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/COโ‚‚ (100% COโ‚‚ 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/COโ‚‚ or tri-mix (He/Ar/COโ‚‚)
    • 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/COโ‚‚ or tri-mix
    • Corrosion resistance: Superior (molybdenum addition)

    Wire Diameter Selection

    DiameterAmperage RangeMaterial ThicknessTypical Use
    0.023โ€30-130A24-18 gaugeAutomotive sheet metal, thin tubing
    0.030โ€40-145A18-14 gaugeGeneral fabrication, light structural
    0.035โ€50-180A14 gauge-1/4โ€Most common all-purpose size

    0.052โ€100-300A1/2โ€+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/COโ‚‚ (C25)

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

    100% COโ‚‚

    • 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/COโ‚‚

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

    AWS Filler Metal Specifications

    AWS A5.18 (Carbon Steel MIG Wire) – Covers ER70S-3, ER70S-6, and other carbon steel wires – Defines chemical composition, tensile strength, and elongation requirements

    AWS A5.9 (Stainless Steel MIG Wire) – Covers ER308L, ER316L, and other stainless wires – Specifies corrosion resistance and ferrite content

    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

    0.052โ€0.052โ€-0.062โ€

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

    Common Mistakes

    Using ER70S-3 on rusty steel
    Low deoxidizers canโ€™t compensate for surface contamination. Result: porosity and weak welds. Use ER70S-6 or clean the base metal.

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

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

    Standard3.93โ€ ร— 2.36โ€9.3 sq in
    Wide-view3.93โ€ ร— 2.87โ€11.3 sq in
    Panoramic4.25โ€ ร— 3.25โ€13.8 sq in

    Larger viewing area improves peripheral awareness in tight spaces and multi-pass work.

    Optical Clarity Rating (1/1/1/1 to 1/1/1/3)

    Four numbers indicate: optical class / light diffusion / variations in luminous transmittance / angle dependence.

    • 1/1/1/1 = highest clarity (minimal distortion)
    • 1/1/1/2 = professional grade
    • 1/1/1/3 = acceptable for general fabrication

    Certification Requirements

    ANSI Z87.1+ (High-Impact Rated)
    Required for all industrial welding environments. Plus symbol (+) indicates high-velocity impact protection.

    CSA Z94.3
    Canadian standard equivalent to ANSI Z87.1+.

    EN379
    European standard covering optical class, switching time, and UV/IR protection.

    Process-Specific Requirements

    TIG (GTAW)

    • Reaction time: 1/20000s or faster
    • Shade range: #5โ€“#13 (low-amp start visibility)
    • Sensitivity adjustment: Essential for low-amperage starts

    MIG (GMAW)

    • Reaction time: 1/10000s acceptable
    • Shade range: #9โ€“#13
    • Spatter resistance: Check lens cover plate availability

    Stick (SMAW)

    • Reaction time: 1/10000s acceptable
    • Shade range: #10โ€“#13
    • Grinding mode: Useful for slag removal between passes

    Flux-Core (FCAW)

    • Same as MIG requirements
    • Higher spatter = more frequent cover plate replacement

    Power Source Options

    Solar-powered

    • Pros: No battery replacement, lighter weight
    • Cons: Requires adequate light exposure, slower recovery in dim environments

    Battery-powered

    • Pros: Consistent performance in all lighting
    • Cons: Battery replacement every 6โ€“12 months (CR2032 or AAA)

    Solar + Battery Hybrid

    • Best reliability for production environments
    • Battery backup prevents downtime

    Buying Checklist

    • โœ“ ANSI Z87.1+ certification marked on helmet
    • โœ“ Reaction time matches your primary process
    • โœ“ Shade range covers your amperage requirements
    • โœ“ Viewing area suits your work environment
    • โœ“ Optical clarity rating 1/1/1/2 or better
    • โœ“ Replacement lens covers readily available
    • โœ“ Adjustable sensitivity and delay controls
    • โœ“ Grinding mode if you do stick or flux-core

    Common Mistakes

    Buying based on viewing area alone
    Large viewing area with slow reaction time = retina damage risk. Verify switching speed first.

    Ignoring optical clarity rating
    1/1/1/3 lenses cause eye strain during 8+ hour shifts. Pay for 1/1/1/2 if you weld full-time.

    Skipping sensitivity adjustment testing
    Low-amperage TIG (10โ€“40A) wonโ€™t trigger poorly calibrated sensors. Test before buying.
