The AC/DC 315 ST is a ready to weld high frequency AC/DC inverter to tackle the most demanding tig applications. This unit offers three phase AC and AC Pulse Tig, as well as DC and DC pulse Tig with precise adjustment for the perfect arc. Whether welding aluminum, stainless titanium or low alloys, the AC/DC 315 ST offers a smooth, stable and focused arc to give you precise control on even the thinnest materials.
The intuitive controls guide you through the various stages of your weld settings and even helps you match your weld settings to the correct tungsten diameter. The 4-meter 260AMP AC @ 100% Duty Cycle UNIarc pro18W torch allows you to easily set your parameter from your torch. Additional features include 2T/4T welding, as well as a built in hot start, arc force and VRD for your SMAW applications. The AC/DC 315 ST boasts a 3-year warranty on parts and labor.
