The company offers units with multivoltage input power that can hook up to either 115- or 230-V, single-phase power outlets.
The 10-lb. 95S is suitable for beginners and home hobbyists. It delivers 95 amps of power on standard 115-V circuits for light maintenance and repair jobs, as well as some light fabrication.
The 161S and 161STL deliver 110 amps on standard 115-V circuits or 160 amps on 230-V circuits. The 161S has arc-force circuits built into the power supply. The 161STL includes user-adjustable arc-force circuits, a trigger hold function, downslope timers, a gas solenoid for flow-through gas, and the ability to use torch switches or a foot control.
The heavy-duty 201TS provides increased control for demanding jobs. It offers a maximum output of 200 amps when used on 230-V circuits.
