Maximize your welding productivity with the Bernard BTB Air-Cooled MIG Gun, model Q5015MV8ESC. This 500-amp welding torch represents the evolution of Bernard's legacy Q-Gun, T-Gun, and S-Gun lines into a single, superior platform known as "Best of the Best" (BTB). Designed for durability and precision, this gun is rated at 500 Amps at 100% duty cycle with CO2 gas, ensuring it can handle the most rigorous welding schedules without overheating or failure.

This assembly features a 15-foot industrial-grade cable that resists cuts, burns, and abrasion, providing long service life in harsh shop environments. The back end is terminated with a Tweco #4 power pin, making it a versatile replacement option for feeders that utilize this common connection style. The gun is set up out of the box for 0.045" (1.2mm) welding wire, streamlining the setup process for heavy-duty fabrication tasks.
