2-2110 - Thermal Dynamics PWH-3A 70-Degree Plasma Welding Torch 12.5ft

Precision Plasma Welding with the PWH-3A

The Thermal Dynamics PWH-3A (Part Number 2-2110) is a premium Plasma Arc Welding (PAW) hand torch designed to deliver exceptional control and consistency in industrial applications. Engineered for use with the Ultima 150 plasma welding system, this torch assembly provides the stability and arc constriction necessary for high-quality welds on stainless steel, titanium, and other sensitive alloys. The package includes the torch body with a 70-degree head angle and a 12.5-foot (3.8-meter) lead assembly featuring Quick Disconnect (QD) fittings.

Optimized Ergonomics and Performance

The PWH-3A is distinguished by its 70-degree head angle, a configuration chosen to provide the optimal balance between visibility and comfort during manual welding operations. Unlike straight torches or 90-degree variants, the 70-degree angle allows the welder to maintain a natural hand position while keeping the tungsten electrode and weld pool clearly in sight. This is critical in plasma welding, where precision and small heat-affected zones are the primary goals. The torch is rated for 150 Amps DCSP (Direct Current Straight Polarity), making it robust enough for a wide range of material thicknesses while maintaining a compact form factor.

Water-Cooled Efficiency

Heat management is vital in plasma welding due to the high energy density of the constricted arc. The PWH-3A utilizes an efficient water-cooling system that circulates coolant through the torch head and leads. This design not only extends the life of the consumables—such as the tip and electrode—but also ensures the handle remains cool to the touch during extended welding cycles. The 12.5-foot lead assembly provides ample reach for bench work or fabrication stations, and the Quick Disconnect system simplifies the process of attaching or removing the torch from the power source and coolant recirculator.

Industrial Reliability

Thermal Dynamics is a leader in plasma technology, and the PWH-3A reflects their commitment to quality. The torch is built to withstand the rigors of daily industrial use. The cable assembly is protected by a durable sheath that resists abrasion and cuts, ensuring longevity in shop environments. Whether you are performing micro-welding on medical devices or fabrication on aerospace components, the PWH-3A provides the reliable arc starting and stability required for critical welds.
