Lincoln Electric SuperArc LA-90 MIG Wire ER80S-D2/ER90S-D2, 0.045″, 500 lb Drum (ED001378): Product Breakdown
“>
Lincoln Electric SuperArc LA-90 MIG Wire ER80S-D2/ER90S-D2, 0.045″, 500 lb Drum (ED001378) is a low-alloy GMAW wire intended for higher-strength steel applications where the filler metal classification matters as much as the base metal and shielding gas. For buyers and weld support teams, the main point is simple: this is not a general-purpose wire. It is a classification-driven consumable that should be matched to the procedure, joint design, shielding gas, and deposit property requirements before release to production.
Key Takeaways
- Classification is the starting point: AWS A5.28 ER80S-D2 / ER90S-D2.
- Wire diameter is 0.045 in, and the package is a 500 lb drum.
- The listing identifies DC+ polarity and common shielding gas use, including 100% CO2 and argon/oxygen blends.
- This product is aimed at higher-strength steel work, not general mild steel fill-in unless the procedure supports it.
- Procedure approval, joint prep, and base metal verification still control the final answer. Unknown (Verify) when uncertain.
What to Verify Before You Buy
For maintenance buyers, the first filter is whether the wire classification matches the job. Check the WPS, base metal spec, and required deposited mechanical properties. ER80S-D2 and ER90S-D2 are not interchangeable by assumption. If your procedure calls for one range, confirm that the wire classification on the spool label and certification paperwork matches that requirement.
Inspect: the wire package size, feed system capability, and storage space for a 500 lb drum. Large drums are efficient for high-volume work, but they create handling and feed-path requirements that smaller spools do not.
Verify: drive roll setup, liner condition, inlet guide size, gun routing, and whether your feeder is configured for drum use. Unknown (Verify) if your feeder, drum adapter, or wire delivery kit is suitable for this package size.
Support Check: Feedability and Setup
Low-alloy solid wire performance is often limited by setup errors, not the wire itself. If the arc is unstable or feed speed is inconsistent, start with the wire path.
- Check drive roll groove size against 0.045 in wire.
- Inspect the liner for wear, contamination, or improper length.
- Verify contact tip condition and bore size.
- Check spool or drum brake tension so wire does not overrun or drag.
- Inspect the inlet guide, gun cable bends, and any pinch points.

Shielding Gas and Polarity
The product description identifies DC+ polarity and common use with 100% CO2 and argon/oxygen blends. That helps narrow selection, but it does not replace a procedure. Gas choice affects arc characteristics, spatter level, penetration profile, and bead shape. The exact procedure may require a specific blend, flow rate, or torch setup. Unknown (Verify) unless your WPS or governing document specifies it.
Check: regulator condition, flow meter accuracy, hose integrity, and gas delivery at the gun. A wire can be correct and still perform poorly if shielding is inconsistent.
Verify: polarity at the machine before loading the wire into production. Reversed polarity can create immediate performance problems and misleading troubleshooting.
WSP Lookup and Filler Metal Selection
If you are building a purchasing or support decision, use the available selection tools as starting points only. They help narrow the search, but they do not guarantee procedure approval.
- WSP lookup page — Unknown (Verify). No lookup page was provided in this request.
- WSP filler metal finder page — Unknown (Verify). No filler metal finder page was provided in this request.
Use any filler metal finder output as a selection starting point, not as a substitute for your WPS, base metal qualification, or code requirement.

Lincoln Electric SuperArc LA-90 MIG Wire ER80S-D2/ER90S-D2, 0.045", 500 lb Drum (ED001378)
SuperArc® LA-90™ is a premium, copper-coated low-alloy MIG (GMAW) wire from Lincoln Electric designed to meet 80,000–90,000 psi tensile strength requirements for higher-strength steel applications. Classified to AWS A5.28 ER80S-D2 / ER90S-D2, LA-90 delivers strong, consistent as-welded mechanical performance across common shielding gas mixes, including 100% CO₂ and argon/oxygen blends, with DC+ polarity.

Practical Troubleshooting Sequence
- Check the wire classification on the label against the WPS.
- Inspect the feed path from drum to contact tip.
- Verify polarity, gas type, and gas flow.
- Check the contact tip for wear or mismatch.
- Inspect the joint prep, mill scale, rust, oil, and moisture.
- Verify whether the issue follows the wire or stays with the machine setup.
If the deposit profile is not meeting expectations, do not jump straight to a different wire class. First confirm that the setup matches the intended procedure. Many apparent filler metal problems are actually feed issues, shielding issues, or base metal prep issues.
Safety Notes
- Follow the applicable WPS, SDS, and site hot-work controls.
- Handle the 500 lb drum with proper lifting equipment. Do not manually lift or reposition it without a safe method.
- Keep hands clear of feed rollers and pinch points during setup.
- Use eye, hand, and respiratory protection as required by the job and local exposure controls.
- Confirm ventilation and fume control before welding on production parts.
FAQ
Is this wire for general mild steel welding?
Not by default. It is classified as ER80S-D2 / ER90S-D2 and should be matched to the procedure and strength requirements. Unknown (Verify) for any mild steel application unless the WPS allows it.What polarity is listed for this wire?
The product description identifies DC+ polarity.Can I use it with any shielding gas?
No. The listing mentions common use with 100% CO2 and argon/oxygen blends, but the actual approved gas depends on your procedure. Treat gas references as a starting point only.What should I check first if feed is unstable?
Check drive roll pressure, liner condition, contact tip wear, cable routing, and drum brake tension before replacing the wire.Sources Checked
