The new Digital Microprocessor controlled 250 Amp PowerTIG 255 EXT and the 320 amp 325EXT will be here soon with some radical new design and improvements over the previous models. Expected delivery will be in March. The units feature wave form control for AC welding, Advanced AC pulse along with standard AC/DC pulse. It features memory function. It also has excellent starting, with low amp capability for AC and DC. The unit also is slated to have an "easy setup" function which features a good starting point for the user for both AC and DC without having to go through a complicated setup process or give the operator a "recenter" point if the customer needs it. The Stick features Hot start time/current control, along with arc force control. Simplified layout and design makes the units easy to set up and assess the programmed parameters. One knob control keeps the adjustments simple and intuitive. This units like the 210EXT feature PowerFactor Correction which improves generator operation and withstands "dirty" power better than ever before. If you have further questions give us a call. Some details are being finalized now and full specs will be available shortly after the first of the new year. This unit is compact and is projected to operate on single phase 240 or 3 phase 240 with a 480V 3 phase option available at customer request. 325EXT is exclusively 3 phase, 240, or 480 (special order). Both units feature true low amp operation with operation down to 3 amps for DC and 5 amps for AC. Units come with the newly designed foot pedal.
