High-Strength MIG Welding Wire for Steel

Image of Product. Front orientation. MIG Welding Wire.

This wire creates stronger welds on steel than standard welding wire for steel.

ER120S-1—ER120S-1 wire creates 40% stronger welds than ER80S-B2, ER80S-D2, and ER110S-1 wire, and also resists impact better. It’s often used in lifting and handling machines.
