Lincoln Electric L-56 MIG Wire .030
This Lincoln Electric L-56 MIG welding wire carries AWS classification ER70S-6 for carbon-steel GMAW work. The .030 inch diameter suits general fabrication, automotive repair and light structural jobs where solid wire is preferred.
Check shielding gas and wire feed setup
Verify that your MIG gun liner, drive rolls and contact tip match the .030 inch diameter before ordering. The wire is rated for 100 percent carbon dioxide, 75/25 argon/CO2, 90/10 argon/CO2 and 98/2 argon/oxygen mixes, so confirm your gas supply matches one of these blends.
Tensile strength varies with gas mix
As-welded tensile strength ranges from 81 ksi with straight CO2 to 84 ksi with 90/10 argon/CO2, while minimum yield strength is 58 ksi across all listed gases. Selecting the appropriate shielding gas therefore directly changes the mechanical properties of the finished weld.

Questions about this item
Does the Lincoln Electric ED030631 spool include a contact tip or do I need to buy one separately?
The spool supplies only the 0.03 in carbon-steel wire classified as ER70S-6; contact tips, liners and shielding gas must be purchased separately.
Should I choose the 0.03 in diameter or a thicker wire for my MIG welder?
The 0.03 in diameter suits light-gauge sheet metal and lower-amp machines; thicker wires require higher amperage and are not interchangeable with this spool.
What does the 81 ksi tensile strength mean when I weld with 100 percent carbon dioxide?
With pure CO2 shielding the deposited weld metal delivers a minimum tensile strength of 81 ksi and a yield strength of 58 ksi.
