HF TIG Inverter Power Supply

The ET 301i AC/DC is a high output, full digital control, AC/DC, Stick/Liftarc TIG/HF TIG, inverter power supply
with expanded input voltage capabilities for maximum flexibility. This unit is specially designed for precision TIG and
Stick welding of all weldable materials. Superior, true square wave output combines with balance
and cleaning features to deliver unbeatable welding performance with extended tungsten life on aluminum
and magnesium alloys without the need for continuous high frequency.

Highlights
