34562 - ESAB Heliarc HW-20 Water-Cooled TIG Torch Assembly, 25 ft

Industrial Grade Water-Cooled TIG Solution

The ESAB Heliarc HW-20 (SKU: 34562) is a premium water-cooled TIG torch assembly designed for high-duty cycle industrial applications. Engineered to meet the rigorous demands of aerospace, power generation, and precision fabrication, this torch system delivers consistent performance at up to 250 amps. The HW-20 body is constructed from high-temperature silicone rubber, ensuring insulation integrity and preventing high-frequency leakage, which is critical for starting arcs in sensitive applications.

This package includes a 25-foot cable assembly sheathed in durable vinyl. The extended length allows operators to work on large assemblies without moving the power source, improving workflow efficiency. The water-cooling system is optimized to extract heat rapidly from the torch head, maintaining a comfortable handle temperature even during prolonged welding sessions. This thermal management extends the life of consumables and reduces downtime associated with overheating equipment.

Compatibility is a key strength of the HW-20 series. It utilizes standard industry consumables (collets, collet bodies, and nozzles), making inventory management simple and cost-effective for procurement departments. The torch connects seamlessly to most standard TIG power sources equipped with a water cooler, providing a versatile solution for diverse welding fleets. Whether welding aluminum, stainless steel, or exotic alloys, the ESAB HW-20 provides the stability and control required for X-ray quality welds.
