One look at the IGBT powered PowerTIG 315 DX tells you that this is a serious, no nonsense heavy duty commercial class inverter TIG/Stick welder. All the features of the 220V 3 phase unit are designed for simplicity and straight forward operation. The rugged, compact design allows the PowerTIG to be used in about any setting whether in shipyards or on the farm. At an impressive 35% duty cycle @315 amps, the PowerTIG 315 DX can handle about any aluminium, stainless, or steel welding task. No job is too small, and no job is too big for this unit. It features programmable Pulse welding function, with fully adjustable AC balance and AC frequency controls, and 2T/4T panel control, or foot pedal controlled welding. Easy arc starting and stability are characteristic of all the Everlast PowerTIG lines and this unit is no exception.
