The ESAB 40V84 is a premium replacement power cable designed specifically for the HW-12 (Heliarc) and WP-12 series of water-cooled TIG torches. In the realm of high-amperage Gas Tungsten Arc Welding (GTAW), the integrity of the power cable is paramount. This component serves a dual purpose: it acts as the primary conduit for the welding current traveling from the power source to the torch electrode, and it simultaneously functions as the return line for the coolant water exiting the torch head. This "power-in-water" design allows for a lighter, more flexible cable assembly compared to separate solid copper cables, which would be unwieldy at 500 amps.
Constructed with high-grade copper stranding, the 40V84 ensures minimal voltage drop over its 25-foot length, maintaining arc stability even at the upper limits of the torch's duty cycle. The copper conductor is encased in a robust, non-conductive rubber hose that is formulated to withstand the rigors of industrial environments. This outer jacket offers excellent resistance to abrasion, cuts, and exposure to ozone or workshop chemicals, ensuring a long service life. The hose material also retains flexibility across a wide temperature range, preventing the stiffness that can lead to operator fatigue or repetitive strain injuries.
The connections on the 40V84 are precision-crimped to ensure a leak-proof seal for the coolant and a low-resistance electrical bond. This is critical for preventing coolant loss, which can rapidly destroy a water-cooled torch head, and for preventing resistive heating at the connection points. As a genuine ESAB part, this cable meets strict OEM specifications for fitment and performance, ensuring seamless integration with existing HW-12 torch bodies and standard water-cooled TIG setups. It is an essential component for maintaining the operational readiness of heavy-duty welding stations used in aerospace, power generation, and heavy fabrication.
