Bernard BTB 400 Amp MIG Gun - 15ft Miller Connection

Experience the pinnacle of welding comfort and performance with the Bernard BTB (Best of the Best) 400 Amp MIG Gun. Created by merging the top features of Bernard’s legendary Q-Gun, S-Gun, and T-Gun lines, the BTB series offers a rugged, industrial solution tailored for the professional welder. This model is specifically configured to handle high-amperage applications up to 400 amps, making it perfect for heavy fabrication shops, construction sites, and manufacturing floors where downtime is not an option.

Superior Ergonomics and Reach
Welding fatigue is a real challenge, and the Bernard BTB gun addresses this with an ergonomically designed handle that fits naturally in the hand. The balanced weight distribution reduces wrist strain, allowing for longer, more precise welds. With a generous 15-foot cable length, you gain the flexibility to move around large workpieces without constantly repositioning your wire feeder. The cable itself is reinforced to resist cuts, burns, and abrasion, ensuring a long service life even in the toughest shop environments.

Seamless Compatibility and Performance
Designed with a Miller-style back-end termination, this gun plugs directly into your existing Miller wire feeders and welders. The solid connection ensures maximum conductivity and reliable arc starting. The 60-degree medium neck provides the ideal angle for accessing a variety of joint configurations, from deep fillets to open butts. Furthermore, the rotatable neck feature allows you to adjust the gun orientation without tools, giving you the adaptability needed for complex weldments.

Centerfire Consumable System
One of the standout features of the Bernard BTB gun is its compatibility with Centerfire consumables. The contact tips drop into the gas diffuser and are locked in place by tightening the nozzle, creating a tapered seat that optimizes electrical transfer and heat dissipation. This design not only extends consumable life but also produces a stable, consistent arc. The threadless contact tips mean you never have to worry about cross-threading or seizing, making changeovers fast and frustration-free. Invest in the Bernard BTB 400A MIG Gun for a tool that works as hard as you do.
