The Dura-Flux self-shielded flux-cored welding gun is now available in six cable lengths ranging from 8 ft to 25 ft, with several new options: a small trigger guard for easier working in tight spaces and a large heat shield to provide better protection from radiant heat. A new heavy-duty contact tip is designed to prevent “arc-out” during welding in deep joints. Dura-Flux’s gun plugs are compatible with all major wire-feeder brands.
