[ HPT / TIG WELDING MACHINE ]
Industrial AC/DC TIG Welding Machine for Metal Fabrication
The HPT TAD-500 AC/DC TIG welding machine offers multiple welding modes, adjustable arc controls and a TIG output current of up to 500 A for industrial metal fabrication applications.
Designed for GTAW (TIG) welding, the HPT TAD-500 combines AC TIG, DC TIG, MIX TIG and STICK welding functions in an inverter-based machine. It supports welding applications involving aluminium, aluminium alloys and other suitable materials.
Operating with a three-phase 415 V input supply, this machine is suitable for evaluating welding requirements in precision metal fabrication, heavy metal fabrication, pipe and tube fabrication, bicycle manufacturing, sports equipment manufacturing, and door and window production.
Multiple Welding Functions and Adjustable Arc Control
The TAD-500 provides built-in pulse welding alongside AC TIG, DC TIG, MIX TIG and STICK functions. Its stable arc-start design and selectable hard or soft arc characteristics allow operators to adjust the welding behaviour according to their requirements.
The machine also offers adjustable welding parameters, including pulse current, upslope and downslope times, gas pre-flow and post-flow times, and MIX TIG settings. Its catalogue specifies a 100% duty cycle at 30°C, giving buyers a documented operating reference when assessing the equipment for their applications.
