PowerTIG 325EXT (240V 1 phase and 240V 3 phase)
The PowerTIG 325EXT is built for superior industrial performance. With Digital microprocessor control over the IGBT inverter, and up to 325 amps of TIG welding Power, the PowerTIG 325EXT packs considerable punch. The IGBT module inverter design creates a reliable and serviceable platform designed for years of service. The unit is equipped with many features that improve its value in the shop. One of the features that is highly useful is the Advanced Pulse in AC which can greatly increase penetration while welding aluminum, and make it seem like you are welding with a lot larger machine than you are. Wave form control, AC frequency and AC balance control combine to round out the welder into a very capable Aluminum welder. However, the DC capabilities should not be overlooked either with plenty of features which includes a standard pulse frequency up to 500 Hz, and a wide range of adjustable 2T/4T functions. The standard PowerTig 325 EXT requires1 or 3 phase 240V input and is available in 3 phase 480V input as well.
