Semi-Automatic MIG Gun Withstands Heavy-Duty Welding, Minimizes Downtime

The T-Gun Semi-Automatic Air-Cooled MIG Gun from Bernard features an aircraft-grade aluminum armored neck with an insulated copper conductor tube rated over 650 amps to prevent overheating even after continuous use. 

To meet the demands of heavy-duty welding applications, Bernard (Beecher, IL) offers its T-Gun Semi-Automatic Air-Cooled MIG Gun. This durable, straight-handle welding gun can be built to order online to ensure users have the features they need to weld in even the harshest and most abusive environments. Users simply answer a series of questions related to amperage, cable length, neck style and more at to customize their own T-Gun Semi-Automatic Air-Cooled MIG Gun.

In addition to its customizable features, this welding gun includes an exclusive Double-Life MIG Gun System, which allows users to flip-flop the front end of the gun when it becomes worn, replacing it with the identical back end to extend the life of the product. The T-Gun Semi-Automatic Air-Cooled MIG Gun also features an aircraft-grade aluminum armored neck with an insulated copper conductor tube (rated over 650 amps) to prevent overheating even after continuous use. Two spare leads, as well as a free control plug (excluding dual schedule models) and power pin are standard with the welding gun.

Adding to its durability, the T-Gun Semi-Automatic Air-Cooled MIG Gun uses TOUGH LOCKConsumables. These nozzles, contact tips and gas diffusers are designed to help dissipate heat and maintain positive electrical conductivity, both features that help the consumables run cooler and last longer. They also help minimize downtime for changeover.

Another time-saving option on the welding gun is the QUICK LOAD Liner, which requires less than half the time and effort to replace compared to conventional-style liners. This two-piece system installs from the front of the welding gun after the user installs a retainer inside the power pin on the first use.

Users may also choose to use the QUICK LOAD Liner AutoLength System in conjunction with the QUICK LOAD Liners. This spring-loaded module sits inside the power pin to apply constant pressure on the liner, keeping it seated properly in the retaining head and helping to minimize wire-feeding problems associated with incorrect liner length.

Bernard offers its T-Gun Semi-Automatic Air-Cooled MIG Gun in standard size models rated at 350, 450, 550, and 650 amps, as well as a Compact Series in a 350-amp model.  The gun is also available with power cables in 10, 12, 15, 20, 25 foot and custom lengths. The Bernard T-Gun Semi-Automatic Air-Cooled MIG Gun was formerly called the Tregaskiss TOUGH GUN Semi-Automatic MIG Gun.
