46V31 - ESAB 46V31 Power Cable for HW-27 Torch, 12.5 ft

Restore Peak Performance to Your Heavy-Duty TIG Setup

The ESAB 46V31 Power Cable is a critical replacement component designed specifically for the legendary HW-27 (also known as the PTW-500) series of water-cooled TIG torches. In the world of industrial welding, the HW-27 is a workhorse, often utilized for high-amperage applications requiring up to 500 amps of continuous power. To maintain this level of performance, the power cable—which acts as the lifeline delivering both electrical current and coolant to the torch head—must be in pristine condition. The 46V31 is engineered to meet these rigorous demands, ensuring that your heavy fabrication projects proceed without interruption.

Constructed with premium-grade materials, this 12.5-foot cable assembly features high-conductivity copper stranding that minimizes voltage drop, ensuring a stable and consistent arc even at the upper limits of the torch's capacity. The copper is encased in a durable, high-temperature rubber hose that serves a dual purpose: it insulates the electrical current for operator safety and provides a leak-proof channel for the cooling water. This integrated design is essential for water-cooled systems, as it efficiently dissipates the intense heat generated during heavy welding, preventing the torch from overheating and extending the lifespan of your consumables.

Over time, TIG power cables can suffer from internal strand breakage due to constant flexing, or the outer jacket may degrade from exposure to hot surfaces and shop grime. A compromised cable can lead to erratic arc starts, coolant leaks, or dangerous overheating. Installing a genuine ESAB 46V31 Power Cable restores the reliability of your equipment. The 12.5-foot length offers a standard reach suitable for most welding benches and production cells, balancing accessibility with cable management. Whether you are welding thick aluminum sections, stainless steel piping, or structural components, this cable ensures your HW-27 torch delivers the power and precision ESAB is known for.
