20018 - ESAB Heliarc HW-27RL 400A Water-Cooled TIG Torch, 12.5 ft

Heavy-Duty Precision for Industrial TIG Welding

The ESAB HW-27RL TIG Torch (SKU: 20018) is a premier solution for heavy-industrial welding applications requiring high amperage and continuous duty cycles. Engineered to handle up to 400 Amps, this water-cooled torch is designed for the most demanding fabrication environments, including aerospace, power generation, and pressure vessel manufacturing. The HW-27 series, often associated with the legendary Heliarc brand, represents the pinnacle of durability and thermal management in the GTAW process.

One of the defining technical features of the HW-27RL is its internal tungsten adjustment mechanism. Unlike standard torches that often require the back cap to be loosened or removed to adjust the electrode, this model allows for precise adjustments to the tungsten stick-out internally. This feature significantly reduces downtime and enhances precision, particularly in automated or high-specification manual welding where arc length and electrode positioning are critical variables. Furthermore, the torch supports both front and back loading of the tungsten, providing versatility depending on the welder's preference and the specific constraints of the welding joint.

The assembly includes a 12.5-foot cable set, typically constructed with high-quality rubber materials to withstand the rigors of the shop floor while maintaining flexibility. The water-cooling system is highly efficient, dissipating the intense heat generated at 400 amps to protect both the consumables and the torch body, ensuring a long service life. For facilities prioritizing equipment longevity and weld quality, the ESAB HW-27RL offers a robust, high-performance interface between the power source and the workpiece.
