The PowerTIG 325EXT is built for superior industrial performance. With Digital microprocessor control over the Infineon IGBT inverter， and up to 320-amp of welding Power， the PowerTIG 325EXT packs the most punch of any AC/DC TIG welder in the Everlast line. The module design of the IGBT's creates a reliable platform designed for years of service. The unit is equipped with many features that improve its value in the shop. 1 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 include a standard pulse frequency up to 500 Hz， and a wide range of adjustable 2T/4T functions. The standard PowerTIG 325 EXT requires 3 phase 240-Volt input and is available in 3-phase 480-Volt input as well.
