WP-27B-3 - Weldcraft W-500B (WP-27B) Automation TIG Torch Kit, 500A, 3ft Rubber

Heavy-Duty Power for Your Automation Rig

If you are running a mechanized welding setup, you know that downtime is the enemy. The Weldcraft W-500B Automation TIG Torch Package (formerly the WP-27B) is built to keep your arc on and your production line moving. This isn't just a standard torch clamped into a holder; it is a purpose-built tool for high-amperage automation. With a massive 500 Amp DC rating (350 Amp AC), this water-cooled beast can handle the heat of continuous welding on heavy plate and thick-wall pipe without breaking a sweat. If your current setup is overheating or struggling to maintain duty cycles, the W-500B is the upgrade you need.

Smart Design for Fast Changeovers
Changing tungsten in a machine torch can be a headache, often requiring you to break down the setup and lose your center point. The W-500B solves this with front and back tungsten loading. You can swap out your electrode from whichever end is most accessible in your fixture, getting you back to welding in seconds rather than minutes. This small detail makes a huge difference over the course of a shift. The torch also features a built-in gas lens, which isn't an optional add-on here—it's standard. This ensures you get smooth, laminar gas flow for a stable arc and clean puddles, reducing the chance of weld defects that could trigger a reject.

Complete 3-Foot Package
This kit (WP-27B-3) comes ready to mount. It includes the W-500B torch body and a 3-foot rubber cable assembly. We prefer rubber over vinyl for industrial environments because it resists kinking and stands up better to hot sparks and accidental contact with hot surfaces. The package also includes the necessary gas and water hoses and a bracket assembly for secure mounting. The 3-foot length is ideal for setups where your wire feeder or connection box is mounted directly on the boom or carriage, keeping cable clutter to a minimum.

Reliability You Can Trust
When you are welding automatically, you can't constantly babysit the torch. You need to know it will perform consistently pass after pass. The Weldcraft W-500B delivers that peace of mind. It connects with standard 3-piece connections (power, water, gas), making it compatible with most industrial water-cooled TIG power sources. Whether you are retrofitting an old machine or building a new cell, this torch provides the heavy-duty performance professional fabricators demand.
