Our most popular MIG wire, SuperArc L-50 , premium copper coated wire, is an excellent choice for 50000 psi (345 MPa) yield strength, carbon steel base materials, SuperArc L-50 has moderate levels of silicon and manganese for deoxidation and cleaning action, designed for use on clean, oil-free and rust-free base material. SuperArc L-50 also has an excellent reputation for feedability and trouble-free performance. Shielding gases include argon/carbon dioxide blends, argon/oxygen blends or straight carbon dioxide

• Moderate levels of manganese and silicon for deoxidization of clean to light mill scale surfaces
• Superior feeding and arc stability
• Copper coated for long contact tip life
• Supports short-circuiting, globular, axial spray and pulsed spray transfer
• Microguard ultra provides superior feeding and arc stability
• 100% Co2, 75 - 95% argon/balance Co2, 95 - 98% argon/balance O2 shielding gas, 30 - 50 cfh flow rate
