The Thermal Arc PWH-3A (2-2527) is a premium water-cooled manual plasma welding torch designed for high-precision industrial applications. Engineered to deliver a concentrated and stable arc, this torch is an essential component for professionals utilizing the Plasma Arc Welding (PAW) process. Unlike traditional TIG welding, the PAW process utilizes a constricted arc forced through a copper nozzle, resulting in higher energy density, deeper penetration, and reduced heat-affected zones. The PWH-3A is specifically built to harness these advantages, making it ideal for welding micro-components, medical devices, aerospace parts, and other applications requiring exacting standards.
This model features a 70-degree head angle, which is ergonomically designed to reduce wrist strain during long welding sessions while providing the operator with a clear line of sight to the weld puddle. The 12.5-foot (3.8-meter) lead assembly offers ample reach, allowing welders to move freely around large workpieces without being tethered too closely to the power source. Rated at 150 Amps DCSP (Direct Current Straight Polarity) with a 100% duty cycle, the PWH-3A is a workhorse capable of sustaining continuous operation without overheating, thanks to its efficient water-cooling system.
One of the standout features of the PWH-3A is its electrode protection. In plasma welding, the tungsten electrode is recessed within the torch body, significantly reducing the risk of contamination from the base metal. This design not only prolongs the life of the electrode but also ensures consistent weld quality over time. The torch is compatible with Thermal Arc power sources, such as the Ultima 150, and is constructed with high-quality materials to withstand the rigors of an industrial environment. Whether you are performing fusion welding or wire-fed applications, the PWH-3A provides the control and reliability needed for superior results.
