Mild Steel, Copper  Coated

Lincoln's premium copper coated MIG wire, SuperArc® L-56 is an excellent choice for welding on  metals with a medium to high presence of millscale. For best performance use on  clean, oil-free, and rust-free base material. Best weld appearance and toe  wetting when compared to ER70S-3 and ER70S-4 classifications. SuperArc® L-56 has  high silicon and manganese deoxidizer levels. Superior feedability and excellent  arc characteristics are trade-marks of SuperArc® L-56. Shielding gases include  argon/carbon dioxide blends, argon/oxygen blends, 100% carbon dioxide, and three  or four-part gas blends.
