MIG Welding Wire for Steel

Image of Product. Front orientation. MIG Welding Wire.

Join steel together with this welding wire.

ER70S-6—ER70S-6 wire is good for welding dirty, oily, and rusty steel. You can also use it to join misaligned pieces together. It creates X-ray quality welds without air pockets for a smoother and more uniform welding bead than standard welding wire. Its high silicon content allows it to flow easily when melted, so it spreads out to fill in the space between two pieces of your weld before hardening.

High-Strength MIG Welding Wire for Steel

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

ER80S-D2—ER80S-D2 wire creates 15% stronger welds than standard welding wire. It can make X-ray quality welds, so it’s often used in applications such as pressure tanks, gas pipes, and heat exchangers.
