SuperArc® LA-90 is our premium copper coated, low alloy MIG wire manufactured to meet tensile strength requirements of 80000 to 90000 psi (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
- Microguard® ultra provides superior feeding and arc stability
- Supports short-circuiting, globular, axial spray and pulsed spray transfer
- 100% Co2 shielding gas, 75 - 95% argon/balance Co2, 95 - 98% argon/balance O2, all welding positions, excellent operator appeal - no gun chatter or feeding instability
- 30 - 50 cfh gas flow
