MIG Wires
Our MicroGuard Ultra surface treatment, with proprietary arc enhancement agents, facilitates excellent weld puddle control,
very good wetting action, straight bead edges and a wider operating range. Plus, the exceptional feeding characteristics of
SuperArc ® and SuperGlide ® , made possible by MicroGuard Ultra surface treatment, translate to reduced down-time and
high operator appeal.

Low Alloy Wire
SuperArc ® LA-75 ER80S-Ni1 SuperArc LA-75 is a premium copper coated, low alloy MIG wire certified to
meet 80,000 psi (552 MPa) minimum tensile strength. Optimal mechanical
properties are achieved with a 98-95% argon, 2-5% oxygen shielding gas
blend. Can be welded with 90% argon, 10% carbon dioxide gas blend, as well
as 75% argon, 25% carbon dioxide mixture. Charpy V-Notch impact testing
meets or exceeds 20 ft. lbs. (27 J) at -50°F (-46°C). LA-75 delivers a weld
deposit with outstanding corrosion resistance for use on ASTM A588
weathering steels.
SuperArc LA-90 ER80S-D2 SuperArc LA-90 is our premium copper coated, low alloy MIG wire
ER90S-D2 manufactured to meet tensile strength requirements of 80,000 to 90,000 psi
(ER90S-G) (552-620 MPa) minimum. The addition of 0.5% molybdenum provides
strength after stress relief. Ideal selection when welding ASTM A182, A217,
A234 and A335 high temperature pipe, fittings, flanges and valves and A336
pressure vessel forgings. Best mechanical properties are achieved with an
98-95% argon, 2-5% oxygen shielding gas blend.
SuperArc LA-100 ER100S-G SuperArc LA-100, our premium copper coated, low alloy MIG wire is designed
(ER110S-G) for use on 100,000 psi (690 MPa) tensile base material and those materials
MIL-100S-1 that require a minimum yield strength of 82,000 psi (565 MPa). Excellent for
(Military) welding on ASTM A514, A543, A724 and A782 quenched and tempered plate
or HY-80 base material. LA-100 provides excellent impact properties under
higher heat input conditions. Best mechanical properties are achieved with an
98-95% argon, 2-5% oxygen shielding gas blend or 95% argon, 5% CO2.
Also meets MIL-E-23765/2C, /2D, /2E specifications as a MIL-100S-1
classification.
“Recently we were experiencing problems with a competitor’s welding wire’s coating
flaking. We decided to make the switch to Lincoln Electric’s SuperArc® L-56 welding
wire. It’s an extremely smooth running wire with excellent puddle control that produces
a quality weld with good penetration.
Along with switching the wire manufacturer we also upgraded from the 30-pound spool
to the 500-pound Accu-Pak box, for both our robotic and manual frame welding
operations. The change enabled us to purchase a better quality welding wire at a very
competitive price. With Lincoln’s wire, our efficiency has increased and we are extremely
pleased that we made the change.”
