UTP A 6222 Mo is a solid wire in a nickel alloy of the NiCrMo-3 type, for corrosion resistant NiCrMo alloys of the 625 group. It is used on chemical process equipment, high temperature installations and mixed joints between nickel alloys and steels.
The wire handles manual semi-automatic work and mechanised stations alike. It also suits cladding runs, that is protective layers built up on steel.

Keep the interpass temperature low and limit weaving, nickel is prone to hot cracking. Watch the wire stick-out from the contact tip, too long a stick-out drops the arc voltage and worsens penetration. Set the gas flow so the pool stays covered along the whole bead, and screen the workstation when you weld outdoors. Match the diameter to the plate thickness and the welding position, thinner wires are easier to control out of position.
