To eliminate overheating common with 18 series 350 amp water-cooled torches, Weldcraft re-engineered the basic WP-18 Series design-- resulting the Super Cool 18® TIG torch. Rated at 400 amps, The SuperCool 18 features a patented water-cooling chamber head design to provide full-flow water cooling that prevents the torches front-end parts from overheating.
The heavy-duty "nose" collet body threads directly into the front of the torch bodies patented water chamber, cooling water flows down, around and up the entire length of the torch head. This design enhances cooling capacity of the torch and eliminates collet and collet body overheating, softening and twisting, especially when welding heavy aluminum alloy with AC current. Optional gas lens are available to improve gas coverage for the most demanding jobs. The Super Cool 18 uses tungsten electrodes in sizes up-to- 3/16" (4.8mm) for high amp continuous AC TIG welding applications.
