The gun body structure is mainly industrial pure copper. Silicone rubber with high dielectric is used for insulation. Assembly of heavy-duty cables-flexible pipes. Installation of fast electrode. The water-cooled gun has extremely strong hydrophobic ability.350 Amp AC/DC (100% duty cycle) Water-cooled body 70º head angle Electrode capacity .020" (0.5mm) -to- 5/32" (4.0mm) Torch body weight 7 oz. (198g) Torch length 7" (177.8mm) Handle diameter 1-1/16" (41.2mm) Water flow 1qt./min. (0.946 L/min.) Maximum pressure 50 psi (3.448 BAR)The WP-18 series water-cooled TIG torch is ideal for high-amperage, continuous duty welding applications. The large cooling chamber head design minimizes overheating and costly downtime due to overheating.  In addition to their superior cooling capacity, the WP-18 series features a comfortably designed handle that helps improve torch control and prevent operator fatigue.
