OVERVIEW

Lincoln SuperArc® LA-90: Precision and Strength in Every Spool

For professional welders demanding consistency and high performance in low alloy steel welding, the Lincoln SuperArc® LA-90 .035" MIG wire is the definitive solution. This wire is formulated to meet the AWS classifications of ER80S-D2 and ER90S-D2, making it a versatile option for projects requiring elevated tensile strength (up to 90 ksi). It is the go-to filler metal for fabricating components that must withstand significant stress and load, thanks to its manganese-molybdenum alloy composition.

Feeding issues can be the bane of productivity on the shop floor. Lincoln Electric addresses this with their Microguard® Ultra technology. This advanced surface treatment ensures that the wire feeds smoothly through the gun liner and contact tip, drastically reducing drag and preventing bird-nesting. The result is a stable, focused arc with minimal spatter, allowing for cleaner welds and less post-weld cleanup. This wire supports a wide range of transfer modes, including short-circuit for thinner gauges and axial spray for heavy-plate penetration, giving you flexibility across different joint configurations.

The 0.50% molybdenum content is not just a spec on a sheet; it provides real-world benefits by retaining strength properties after post-weld heat treatment (stress relief). This makes the LA-90 ideal for piping, heavy machinery, and automotive structural components. The 44 lb spool size ensures you have enough material to keep the arc on for long shifts, maximizing your arc-on time and efficiency.

Key Applications:

High-strength low-alloy (HSLA) steel fabrication
Heavy equipment and machinery repair
Structural steel projects requiring 80-90 ksi tensile strength
Automotive frames and chassis
Pressure vessels and piping

FAQ

Lincoln SuperArc LA-90 meets the requirements for both AWS ER80S-D2 and ER90S-D2 classifications.

Common shielding gases for ER80S-D2/ER90S-D2 wires include Argon/CO2 blends (such as 75/25 or 90/10) for spray transfer and smoother arcs, or 100% CO2 for deeper penetration, depending on the specific application and transfer mode.

The wire is capable of producing weld deposits with a tensile strength between 80,000 and 90,000 psi (550 - 620 MPa).

Yes, SuperArc LA-90 contains approximately 0.50% Molybdenum, which enhances strength, particularly after stress-relief heat treatment.

Microguard Ultra is Lincoln Electric's proprietary surface treatment and copper coating that improves wire feeding, arc stability, and liner life by reducing friction.

As a solid MIG wire, it can be used in all positions (flat, horizontal, vertical, overhead) depending on the transfer mode (e.g., short-circuit vs. spray) and welding parameters used.

This specific product comes on a 44 lb (approximately 20 kg) spool.

Yes, SuperArc LA-90 supports short-circuiting, globular, axial spray, and pulsed spray transfer modes.
