WP-27B - Weldcraft W-500B (WP-27B) 500A Water-Cooled TIG Torch Body

Heavy-Duty Weldcraft WP-27B TIG Torch Body

The Weldcraft WP-27B, also known in the modern Miller lineup as the W-500B, is a powerhouse TIG torch body designed for the most demanding industrial applications. Engineered to handle up to 500 amps of DC current, this water-cooled torch body is the standard for heavy fabrication where heat management and duty cycle are critical. The WP-27B is distinct from standard handheld torches due to its robust barrel and bracket assembly, making it an excellent choice for mechanized or automated welding setups where stability and precision are paramount.

One of the standout features of the WP-27B is its integrated gas lens system. Unlike standard torches that may require aftermarket gas lens kits, this body comes with a built-in gas lens that ensures laminar gas flow right out of the box. This results in superior shielding gas coverage, reduced turbulence, and a cleaner weld pool, which is essential when welding reactive metals like titanium or high-grade stainless steel at high amperages. The cooling efficiency of the water-cooled design prevents the torch from overheating during prolonged weld cycles, protecting both the consumables and the operator's equipment.

Operational flexibility is at the core of the WP-27B design. It features a unique front or back tungsten loading capability, allowing operators to replace or adjust the electrode without dismantling the entire setup. This is particularly advantageous in fixture-mounted applications where access might be restricted. The internal tungsten adjustment mechanism further refines the user experience, offering precise control over electrode stick-out. Whether you are replacing a worn-out unit or building a new high-amperage TIG station, the Weldcraft WP-27B from Josef Gas delivers the reliability and performance required for professional results.

This package includes the torch body, barrel, shaft assembly, bracket assembly, and insulating boot, providing the core components needed to get your heavy-duty TIG system operational. It is fully interchangeable with older HW-27 style parts, ensuring backward compatibility for existing production lines.
