Q3015AE7CT - Bernard Q-Gun 300A MIG Torch, 15ft, Tweco Connection, .035 Wire

Heavy-Duty Bernard 300 Amp MIG Gun with Tweco Connection

The Bernard Q3015AE7CT is a premium 300 Amp MIG welding gun designed for professional industrial applications. Part of the renowned Q-Gun series, this torch is engineered to withstand the rigors of heavy fabrication while providing consistent, high-quality weld delivery. It comes pre-configured with a 15-foot cable, offering significant reach for working around large assemblies or fixtures without moving the wire feeder constantly. The gun is set up for 0.035-inch wire, making it an immediate solution for standard steel fabrication tasks.

One of the standout features of this model is its Tweco-style back end. This universal power pin configuration allows the gun to connect seamlessly with a vast array of wire feeders and power sources that utilize the Tweco standard, including equipment from Lincoln Electric, ESAB, and Thermal Arc. This compatibility makes it an excellent replacement or upgrade option for shops with mixed equipment fleets.

Reliability is at the core of the Bernard design. The gun utilizes the Centerfire consumable system, which is favored by welders for its ease of use and performance. The contact tip drops into the gas diffuser and is locked in place by the nozzle, ensuring excellent electrical conductivity and better heat dissipation. This results in longer consumable life and fewer arc faults. The 300-amp rating is a 100% duty cycle rating when using CO2 gas, ensuring the gun stays cool even during prolonged welding segments.

Key Industrial Benefits

• Robust Construction: Built to survive drops and rough handling in shipyard or structural steel environments.


• Efficient Cooling: Air-cooled design optimized to handle high amperage without overheating the handle.


• Versatile Connection: Tweco power pin ensures broad machine compatibility.
