Weldcraft® W-350 (WP-18) Engineered for Continuous Duty Applications

The WP-18 series water-cooled TIG torch is ideal for high-amperage, continuous duty welding applications.  Available in four styles, WP-18, WP18SP and the WP-18V each feature a large cooling chamber head design that minimizes overheating and costly downtime due to overheating.

In addition to their superior cooling capacity, the hand-held WP-18, WP-18V, WP-18SP feature comfortably designed handles that help improve torch control and prevent operator fatigue. The WP-18V torch model includes a built-in gas control valve that provides operators with a quick and easy control of shielding gas flow.
