Forney 42290 Mig Welding Wire, .024 In, Mild Steel, 2-lb. Spool

Forney 42290 is an ER70S-6 mild steel MIG welding wire designed for high-strength welds on ferrous metals. This .024-inch diameter wire is ideal for auto body repair, fabrication, and general maintenance welding on carbon steel. The copper-coated wire performs reliably on less-than-perfect steel surfaces, eliminating the need for extensive surface preparation before welding.

The wire's chemistry combines manganese and silicon to deliver excellent weld quality even on rusty or dirty steel. It produces a smooth, clean bead that requires minimal post-weld grinding, saving time and effort. The high silicon content ensures fluidity in the weld puddle and superior arc performance. This spool is suitable for both butt and fillet welds in industrial, farm, construction, and automotive applications.

Features and Benefits

• ER70S-6 Formulation: High manganese and silicon content enables strong, clean welds on less-than-perfect or dirty steel without extra prep work.
