The Bernard BTB (Best of the Best) Semi-Automatic Air-Cooled MIG Gun (SKU: Q4015MS3ETC) is a premium welding solution designed for high-amperage industrial environments. Rated at 400 Amps, this torch is engineered to withstand the rigors of heavy fabrication, structural steel, and manufacturing applications. It features a 15-foot cable, providing operators with significant reach and flexibility around large workpieces without compromising wire feeding performance.
This specific configuration is equipped with a Tweco-style rear connection, making it compatible with a wide range of wire feeders and power sources that utilize the standard Tweco termination. The gun comes pre-setup for 0.045-inch wire, a common diameter for structural and heavy-plate welding. At the core of its design is the renowned Q-Gun style curved handle, which has been an industry favorite for years due to its ergonomic shape that reduces wrist fatigue and improves operator control during extended welding sessions.
As part of the BTB platform, this gun utilizes Bernard's high-performance consumables, typically the Centerfire system, which ensures superior arc stability and longer contact tip life. The air-cooled power cable is robust and designed to resist cuts, burns, and abrasion, ensuring a long service life even in harsh shop conditions.
