The Powercraft PTAD 315PHD is a professional AC/DC TIG inverter welding machine engineered for high-performance industrial and fabrication applications. Unlike standard DC TIG welders, this model supports both AC and DC TIG welding, allowing it to weld a wider range of materials including aluminum, stainless steel, mild steel, copper, and other non-ferrous metals. Its inverter technology provides stable arc performance, efficient power consumption, and precise welding control for clean and consistent welds.

With an output range of 20–300A and a 60% duty cycle, the PTAD 315PHD is suitable for medium to heavy-duty welding operations. It also supports ARC (stick) welding, making it a versatile machine for fabrication shops, maintenance facilities, automotive work, and industrial manufacturing. The machine is built for durability with a heavy-duty design and forced-air cooling system to maintain reliable performance during extended use.

Key Features:

• AC/DC TIG welding capability for aluminum and steel applications
• Supports TIG and ARC (stick) welding processes
• Stable inverter-based arc control
• Suitable for precision and heavy fabrication work
• High-frequency arc ignition for smoother starts
• Industrial-duty construction for continuous operation
• Single-phase power compatibility
