2-2846 - Thermal Dynamics PWM-300 Plasma Welding Torch with 25ft Leads

Precision Plasma Arc Welding Technology

The Thermal Dynamics PWM-300 is a high-performance Plasma Arc Welding (PAW) torch designed for industrial applications requiring precision, consistency, and high amperage capacity. Engineered by Thermal Dynamics (a leader in plasma technology), this torch assembly (SKU 2-2846) includes the torch head and a 25-foot lead set, providing the necessary reach for complex fabrication setups. The PWM-300 is rated for 300 Amps, making it suitable for a wide range of material thicknesses, from thin gauge precision work to heavier structural welds where the concentrated energy density of plasma is advantageous.

In the realm of industrial gas applications, the Plasma Arc Welding process distinguishes itself by utilizing a constricted arc. The PWM-300 facilitates this by channeling the plasma gas through a fine bore copper nozzle, ionizing the gas to create a stiff, columnar arc. This results in deeper penetration and a narrower heat-affected zone compared to traditional TIG welding. The torch is water-cooled, a critical feature for maintaining conductivity and preventing overheating during prolonged operation at 300 Amps. Proper coolant flow ensures the longevity of the tungsten electrode and the constricting nozzle, which are central to the torch's operation.

This assembly is designed for integration with compatible Thermal Arc plasma welding consoles. The 25-foot leads are shielded and bundled to withstand the rigors of the industrial environment while delivering the necessary power, pilot arc current, and cooling fluid to the torch head. For facilities focused on high-purity welding—such as aerospace, medical device manufacturing, or nuclear components—the PWM-300 offers the control and stability required to meet stringent radiographic standards.
