Argon / Helium
Argon and Helium mixtures are used mainly when welding Nickel based alloys and Aluminum. The mode of transfer is either spray transfer or pulsed spray transfer. The addition of Helium provides a more fluid weld pool, flatter bead shape and increased travel speeds.
Helium reduces the appearance of Hydrogen pores in welds using Aluminum and Magnesium fillers with 5000 series base alloys. The Argon provides excellent arc starting and promotes a cleaning action on Aluminum.
