49V30 - HW-27 Replacement TIG Torch Body Assembly 500A

Restore Your Heavy-Duty Welding Power

When you are pushing 500 amps on a thick aluminum casting or welding heavy-wall stainless pipe, your equipment takes a beating. The HW-27 (or WP-27) style torch is the workhorse of the heavy industrial TIG world, but even the toughest torches need maintenance. The ESAB 49V30 Body & Tube Assembly is the direct replacement part you need when your torch head threads strip out, the water lines develop a leak, or the insulation becomes compromised. Don't let a failing torch body compromise your weld quality or safety; swapping in a fresh 49V30 brings your rig back to factory-new performance.

This assembly isn't just a spare part; it's the heart of your water-cooled system. It features a robust copper construction designed to flow massive amounts of current without overheating, provided your water cooler is running efficiently. The integrated water tubes ensure that coolant circulates right up to the collet body, pulling heat away from the tungsten and preventing meltdown during long, continuous welds. The high-quality silicone rubber coating offers excellent grip and heat resistance, protecting your hands from the intense radiation of a 500-amp arc.

Why replace the body? Over time, the constant heating and cooling cycles can fatigue the metal, and the frequent changing of cups and collets can wear down the threads. A worn thread can lead to poor electrical contact, causing the torch to run hot and potentially melting your consumables. A small coolant leak inside the handle can destroy your power cable or cause porosity in your welds. By installing a new 49V30 Body & Tube Assembly, you eliminate these variables. You get a solid, leak-free foundation that holds your tungsten steady and directs gas flow precisely where you need it.

Designed for the professional welder, this body fits the classic "Heliarc" style handle that many veterans prefer for its balance and durability. It is compatible with all your existing 27-series consumables, so you don't need to buy new cups or collets. Whether you are working in a fabrication shop, a shipyard, or on a pipeline, having a reliable torch is non-negotiable. Trust the ESAB 49V30 to keep you welding at maximum amperage, shift after shift.
