0700300433 - ESAB HW-20 Rigid Water-Cooled TIG Torch Body

Genuine ESAB Replacement for Heliarc Systems

The ESAB HW-20 Rigid Water-Cooled TIG Torch Body (0700300433) is a critical component for maintaining the performance of your Heliarc HW-20 TIG welding system. Designed to meet the exacting standards of professional fabricators, this torch body serves as the core structural and conductive element of the torch assembly. It features a rigid head design, which provides a fixed angle for the tungsten electrode, ensuring consistent arc manipulation and superior durability compared to flexible alternatives in heavy-duty environments.

Engineered for high-amperage applications, this torch body utilizes an advanced water-cooling channel system. This design efficiently dissipates heat generated during the welding process, allowing the torch to operate at 100% duty cycle at its rated amperage (typically up to 300A DC). This thermal management is essential for preventing overheating, extending the life of consumables (collets, collet bodies, and nozzles), and ensuring operator comfort during prolonged welding sessions.

The body is constructed from high-grade copper and brass alloys, selected for their excellent electrical conductivity and resistance to thermal shock. The rigid flange ensures a secure connection to the torch handle and cable assembly, preventing leaks and maintaining electrical integrity. Whether you are repairing a damaged torch or refurbishing an older Heliarc unit, the ESAB 0700300433 ensures OEM fitment and performance.
