Dura-Flux Self-Shielded Flux-Cored Gun with Fixed Cable Liner

Built to optimize comfort and meet the demands of heavy-duty self-shielded flux-cored application

Self-shielded flux-cored welding can be brutal on both you and your welding equipment. That’s why Bernard designed the Dura-Flux™ self-shielded flux-cored gun to be extremely durable, yet comfortable to hold and use.

Our Dura-Flux self-shielded flux-cored gun meets the demanding needs and harsh environments of construction, shipbuilding, heavy manufacturing and rental applications. Triggers are non-metallic and absorb less heat. The triggers are also made with a sealed micro switch that helps keep out dust and dirt to provide a long-lasting work life.
