Lincoln Electric L-56 MIG Wire .030 in
Lincoln Electric L-56 MIG welding wire comes on a spool with a .030 inch diameter. It is made from carbon steel and carries AWS classification ER70S-6 for MIG welding processes.
Who this suits and who it does not
This wire suits welders joining mild steel with MIG equipment using carbon dioxide or argon-based shielding gases. It is not for flux-cored processes, aluminium welding, stainless steel applications or jobs requiring a different wire diameter.
Tensile strength by shielding gas
Tensile strength varies with the shielding gas: 81 ksi with 100 percent carbon dioxide, 82 ksi with 75 percent argon and 25 percent carbon dioxide, 84 ksi with 90 percent argon and 10 percent carbon dioxide and 82 ksi with 98 percent argon and 2 percent oxygen. Minimum yield strength is 58 ksi.

Questions about this item
Will the .030 in L-56 wire feed smoothly through my older MIG gun liner and drive rolls?
The .030 in diameter matches standard liner and drive-roll sizes for most hobby and light-industrial MIG guns, so it will feed without changing consumables.
How can I verify the ER70S-6 wire is producing sound welds after I start welding?
Check for a smooth, uniform bead with good tie-in, minimal spatter, and tensile strength near 81 ksi with 100 % CO2 or 84 ksi with 90/10 Ar/CO2 shielding gas.
Does the spool include any shielding gas or contact tips, or must I buy them separately?
The package contains only the L-56 carbon-steel MIG wire spool; shielding gas, contact tips, liners and drive rolls are sold separately.
