948350R - HW-18R Replacement TIG Torch Body 60 Degree

Industrial Grade Water-Cooled TIG Torch Body

The ESAB HW-18R Body (SKU: 948350R) represents a critical component for high-amperage Gas Tungsten Arc Welding (GTAW) systems. Designed as a direct replacement for the classic HW-18 series torches, this body is engineered to withstand the rigorous thermal demands of continuous heavy-duty welding. The unit features a water-cooled architecture, essential for maintaining operating temperatures within safe limits during prolonged welding cycles at amperages up to 350A DC or 260A AC. The efficient heat dissipation provided by the internal water chambers ensures the longevity of both the torch body and the consumable components, reducing downtime associated with overheating.

A distinguishing specification of this model is its 60-degree head angle. While standard TIG torches often utilize 70-degree or 90-degree configurations, the 60-degree geometry of the HW-18R provides a specific angular approach that can be advantageous in restricted access scenarios or for operators who prefer a straighter torch alignment relative to the workpiece. This geometric variation allows for optimized tungsten positioning in complex joint configurations, such as pipe root passes or confined structural corners.

Constructed with high-grade, heat-resistant silicone rubber insulation, the torch body offers superior dielectric strength and resistance to high-frequency voltage leakage. The internal conductive components are machined from heavy-duty brass alloys to minimize electrical resistance and maximize current transfer efficiency. This body is fully compatible with standard 18-series front-end consumables, including collets, collet bodies, gas lenses, and alumina nozzles, ensuring seamless integration into existing inventory and supply chains. It is an OEM-quality component designed to restore the performance parameters of ESAB and compatible Heliwelder-style torch assemblies.
