Powercraft DC TIG ARC Inverter Welding Machine PTW 300HD:

The PTW 300HD is a heavy-duty DC TIG and ARC inverter welding machine built for fabrication shops, industrial maintenance, and continuous welding operations. It supports both TIG and stick (ARC) welding processes, making it suitable for stainless steel, mild steel, and general structural work. Its 100% duty cycle at 300A allows long welding sessions without frequent cooling stops. The machine can handle welding thicknesses from 1.5 mm up to 13 mm and supports welding rods from 2.5 mm to 4.0 mm. Despite its industrial-grade power, inverter technology helps keep power consumption and weight manageable.

Powercraft DC TIG ARC Inverter Welding Machine PTW 250i:

The PTW 250i is a mid-range DC TIG and ARC inverter welding machine intended for light to medium industrial applications. It offers a balance between portability and welding power, making it suitable for fabrication shops, maintenance work, and on-site welding jobs. Compared with the PTW 300HD, it is lighter and consumes less power while still providing enough output for most common steel fabrication tasks. It supports TIG welding up to 250A and ARC welding up to 250A with a 60% duty cycle.
