Forney 2-Pound Spool MIG Wire

The Forney 42291 .030 (ER-7OS-6) Mild Steel MIG welding wire is a high strength mild steel MIG wire, ideal for auto body repair and fabrication on most ferrous metals. With a high level of manganese and silicon, this wire ensures a superior weld, even on rusty, dirty steel, resulting in a smooth bead that requires less grinding. However, it is not recommended for use on aluminum engines. The yellow color coding on the label makes it easily identifiable.

When selecting MIG welding wire, it is crucial to consider the base metal composition. The finished weld metal should have mechanical properties similar to those of the base material. Forney Industries, established in 1932, is a family-owned company offering over 5,000 products for various markets such as hardware, automotive, farm, and ranch. We are dedicated to providing solutions to all your metalworking needs, regardless of your location or requirements.

The Forney 42291 MIG wire boasts a tensile strength of 70,000 PSI, with a DCEP Reverse Polarity and requires an Argon/CO2 mix as shielding gas. The wire diameter is .030-Inch (.8mm), weighing 2-Pounds (.907 Kg). Classified as ER70S-6, the (ER) represents Electrode or Rod, while the (70) denotes the tensile strength. The (S) indicates solid wire, and the (-6) signifies the chemical composition and shielding gas required for welding.

This classification as a -6 wire makes it easier to use on less than clean materials that may have rust or dirt present. The warranty for this product must be claimed within 90 days of purchase, with proof of purchase required. However, the warranty does not cover misuse, neglect, negligence, accidents, or any use contrary to the intended purpose.

With a high level of manganese and silicon, this all-position copper coated welding wire is designed for welding on dirty or rusty steel. The high silicon content allows for fluidity of the weld puddle, resulting in a smoother bead appearance and reducing the need for post-weld grinding. The superior wire surface finish ensures the best feed ability and arc performance, while the increased manganese and silicon offer excellent cleaning action.

This wire is suitable for butt and fillet welding of carbon steel sheet and plate in industrial, farm, construction, and automotive equipment applications. It requires CO2 or Argon/CO2 shielding gas, which is not included.
