Weldcote Metals MIG Welding Wire, .045"X44Lbs

Weldcote Metals MIG Welding Wire, .045"X44Lbs

The WS604544 Weldcote Metals MIG Welding Wire (.045" × 44 lb) is an ER70S-3 solid MIG wire designed for single-pass and multi-pass welding, offering reliable performance on mild steel, including material with light mill scale. Its chemistry provides sufficient deoxidation to support welding with 100% CO₂ or mixed shielding gases, and the copper coating helps protect the wire surface while promoting a slag-free weld bead for easier post-weld cleanup. ER70S-3 typically runs with less silicon and may be not as smooth compared to some alternatives, with typical base metal specs often similar to ER70S-2.
