BQ3015AE7CMC - Bernard Q-Gun 300A MIG Torch 15ft Miller Plug

Industrial-Grade 300 Amp MIG Gun for Miller Feeders

The Bernard Q-Gun 300 Amp MIG Gun is a premier choice for industrial welding applications requiring reliability, durability, and ease of maintenance. Engineered to withstand the rigors of heavy fabrication environments, this air-cooled gun is rated at 300 amps, making it suitable for a wide range of wire diameters and material thicknesses. The 15-foot cable assembly offers significant reach, allowing operators to maneuver around large workpieces without constantly repositioning the wire feeder.

This specific configuration features a direct Miller back-end connection, ensuring seamless integration with popular Miller wire feeders and power sources such as the Millermatic series and various industrial feeders. The connection is robust, providing excellent conductivity and gas flow consistency. One of the standout technical features of the Q-Gun is the inclusion of the Centerfire consumable system. Unlike traditional threaded tips, the Centerfire system uses a drop-in contact tip that is locked in place by the nozzle, resulting in better heat dissipation and consistent electrical contact.

Maintenance and downtime are critical metrics in any production facility. The Bernard Q-Gun addresses this with a user-friendly design that simplifies liner replacement and consumable changes. The rotatable neck feature allows the gun to be adjusted to different angles without tools, facilitating access to complex joints and reducing strain on the cable assembly. The heavy-duty power cable is reinforced to resist cuts, burns, and abrasion, ensuring a long service life even in harsh shop conditions.
