Bernard Weld offers its self-shielded flux-cored gun, the Dura-Flux. To increase operator comfort, Dura-Flux guns feature a non-metallic trigger that absorbs less heat than metal triggers. The trigger is also made with a sealed microswitch, which keeps out dust and dirt, to provide a long work life. Welders will also appreciate the smaller trigger guard, which improves maneuverability compared to guns with larger heat shields. The small trigger guard doesn’t obstruct access to narrow access joints the way the larger heat shields do. The Dura-Flux is rated to 350 amps at 100 percent duty cycle and can handle higher current loads at reduced duty cycles. It accepts flux-cored wire up to 3/32-in. and is equipped with a heavy-duty monocoil power cable and Bernard’s Centerfire contact tips, which last up to three times longer than other brands.
