The Everlast PowerARC 140STi from is our small portable IGBT inverter welder  that features both Stick and DC Live Lift TIG capability.  It comes with its own carrying case and includes the Stick holder with the cable and DINSE style connector, a gas valve TIG torch with cable and DINSE connector and the work clamp.    The arc quality on the PowerArc 140STi is on the level of much larger, commercial class machines.   The welder features both adjustable hot start and arc force control in Stick mode that improves weld-ability with hard to start welding electrodes and in situations where rod sticking can be a problem. With TIG and Stick functions, at 220v this unit can operate from 5 to 140 amps. At 110v, it will operate from 5-80 amps.  The PowerARC 140STi  is 120V/240V dual-voltage, which allows the unit to go and weld virtually anywhere there is a clean power source available.  NOTE: An argon regulator is not included so if you plan on TIG welding you will need to purchase one (go to the ACCESSORIES TAB and click on TIG TORCHES AND ACCESSORIES).

Product Notes:

This unit needs a minimum 5500 watts (120V) to operate properly. Use with generators certified as clean power by the generator manufacturer (10% total harmonic distortion). Damage cause by operating on generators that are not the proper size and type are not warrantied.
Not recommended for welding with E 6010. 

TIG is DC output only.
