FLX3515BM - Bernard Dura-Flux 350A Flux-Cored Welding Gun, 15ft Cable

Heavy-Duty Flux-Cored Welding Solution

The Bernard Dura-Flux 350 Amp MIG Gun (SKU: FLX3515BM) is an industrial-grade welding torch engineered specifically for the demands of self-shielded flux-cored arc welding (FCAW-S). Designed to operate in harsh environments such as structural steel erection, bridge construction, and heavy equipment repair, this gun delivers reliable performance where shielding gas is not required. The unit is rated at 350 amperes, providing ample power for high-deposition welding wires commonly used in heavy fabrication.

One of the defining technical features of this model is its Fixed Liner system. Unlike universal guns that use replaceable liners which can sometimes allow liner movement or buckling, the fixed liner in the FLX3515BM is permanently secured within the power cable. This design rigidity significantly improves wire feedability, reducing the friction and drag that often lead to wire chatter or bird-nesting, particularly with the aggressive knurled drive rolls used for flux-cored wire. The 15-foot cable length offers significant reach, allowing operators to move freely around large workpieces without constantly repositioning the wire feeder.

The gun is built with high-impact, heat-resistant materials that protect internal components from the intense heat and spatter typical of flux-cored welding. It utilizes Bernard's industry-standard consumable systems, ensuring that replacement contact tips and insulators are readily available and easy to change out in the field. For procurement specialists and facility managers, the Bernard Dura-Flux represents a long-term investment in uptime and weld quality, minimizing equipment failures during critical project timelines.
