2-2115 - Thermal Dynamics PWH-3A Hand Plasma Torch 90-Deg 25ft

Precision Plasma Welding with the PWH-3A

The Thermal Dynamics PWH-3A (Part Number 2-2115) is a high-performance hand-held plasma welding torch engineered for precision and durability. Designed to operate seamlessly with the Thermal Arc Ultima 150 Plasma Welding System, this torch brings the advanced benefits of Plasma Arc Welding (PAW) to manual operators. Unlike standard Gas Tungsten Arc Welding (GTAW), the PWH-3A utilizes a constricted arc, which provides significantly higher energy density, a more focused heat input, and exceptional arc stability, even at very low amperages. This makes it the tool of choice for welding thin foils, medical components, and intricate aerospace parts where heat control is paramount.

This specific configuration features a 90-degree head angle, which is widely preferred for bench-top applications and general fabrication where the operator needs a comfortable hand position relative to the workpiece. The torch is rated for 150 Amps DC Straight Polarity (DCSP) at a 100% duty cycle. This industrial-grade rating means the torch can operate continuously at its maximum output without requiring cool-down periods, maximizing productivity in high-volume manufacturing environments. The water-cooled design is critical to this performance, efficiently removing heat from the torch body and consumables to prevent overheating and extend part life.

The assembly includes 25-foot (7.6-meter) leads, providing ample reach for working on large assemblies or fixtures located away from the power source. The leads are terminated with Quick Disconnect (QD) fittings, simplifying the process of attaching and detaching the torch from the Ultima 150 console. This feature is particularly useful in shops that switch between different torch configurations or need to store equipment securely at the end of a shift. The PWH-3A is robustly constructed to withstand the rigors of daily industrial use while maintaining the delicate control required for micro-welding applications.

Operators will appreciate the ergonomic handle design, which reduces fatigue during long welding sessions. The torch accommodates a range of tungsten electrode sizes and orifice diameters, allowing users to tailor the arc characteristics to the specific material thickness and joint design. Whether you are repairing tool and die molds or fabricating hermetically sealed sensors, the PWH-3A delivers the consistent, high-quality arc required for critical welds.
