WP-18 Water-Cooled Torch Body 350 A

The Miller Weldcraft WP-18 is a water-cooled TIG torch body rated for 350 amperes at a 100 percent duty cycle. It features a rigid neck design and accepts electrodes up to 5/32 inch diameter. This torch body is built for professional GTAW welding applications. It suits demanding fabrication and repair environments.

Suited For Continuous High-Amperage TIG Work

This torch body suits welders running continuous high-amperage TIG jobs such as aluminum fabrication, ship repair, pressure vessel work and pipe fabrication. The water-cooled design manages heat during long runs. It is not for operators needing a flexible neck or those working only at low amperage where an air-cooled torch is lighter and simpler.

350 A at 100 % Duty Cycle

The defining specification is the 350 ampere maximum current at a 100 percent duty cycle with water cooling. This rating confirms the torch can sustain full output continuously without overheating. Verify your power source and cooling system match this capacity before installation.

Questions about this item

Does the WP-18 torch body accept the standard 5/32 inch maximum electrode size?

Yes, the WP-18 is rated for a maximum electrode diameter of 5/32 inch.

How do I connect the water lines to the WP-18 torch body, and what step is often missed?

Attach the water hoses to the torch body fittings, then verify coolant flow before welding; operators often forget to confirm circulation.

When should the rigid neck or consumables on this 350 A water-cooled torch be replaced?

Replace the rigid neck if it cracks or distorts from heat, and change collets, collet bodies and nozzles when they show wear or no longer grip the 5/32 inch electrode.
