• CC - Stick Crisp
• DC TIG
• CV - Wire – For MIG and Metal-Cored
• CV - Innershield® and Outershield®
Flux-Cored
• Arc Gouging – Accessible from All
Modes – Plenty of power to handle a
5/16 in (7.9 mm) carbon
All input voltages and frequencies are both
single and three phase rated - No output
derating necessary on single phase.
5-425 amp output range - For all
recommended processes from DC TIG to arc
gouging.
Input voltage from 208-575 and 50 and 60
Hz operation - One machine runs on virtually
any input power supply.
Touch Start TIG® - For contamination-free
starts.
Low power consumption for energy
savings - 88% efficiency.
Parallel two units - For 700A carbon arc
gouging.
Bright, large digital amp and volt meters
are easy to monitor - Even in sunlight – and
presettable for precise procedure control.
Rugged skid and tube handles - For
