Why Choose the Bernard BTB Gun?

• Superior Consumables: Equipped with the legendary Centerfire™ system, this gun ensures better gas coverage and longer tip life. The threadless contact tips drop right in, meaning you spend less time fiddling with parts and more time burning wire.
• Maximum Comfort: The ergonomic curved handle is designed to fit naturally in your hand, reducing grip force and wrist strain. This means you can maintain a steady hand and produce higher-quality welds even at the end of a long shift.
• Built Tough: From the armored cable jacket to the heavy-duty strain reliefs, every component is built to withstand the harsh reality of the welding shop. It resists heat, spatter, and rough handling.

This specific setup is tailored for Miller welding machines, featuring a direct-connect Miller power pin. It is pre-lined and tipped for .045" wire, making it perfect for structural steel, heavy fabrication, and general manufacturing. The air-cooled design is low-maintenance and reliable, eliminating the complexity of water-cooled systems while still handling high-amperage applications. Invest in a tool that works as hard as you do—the Bernard 400A MIG Gun delivers the reliability and performance professional welders demand.
