Q3025AE4MA - Bernard Q-Gun 300A MIG Torch, 25ft Cable, Miller Connection, .045 Wire

Industrial Grade 300 Amp MIG Gun

The Bernard Q300 MIG Gun (SKU: Q3025AE4MA) is a premium air-cooled welding torch designed for heavy-duty industrial applications. Engineered to withstand the rigors of high-volume manufacturing and fabrication environments, this gun is rated for 300 Amps at 100% duty cycle when using CO2 shielding gas. This specific configuration comes equipped with a 25-foot cable, providing exceptional reach for working on large assemblies without moving the wire feeder.

Centerfire™ Consumable System

One of the standout features of the Bernard Q-Gun series is the integration of the Centerfire™ consumable system. Unlike traditional threaded tips, Centerfire contact tips are "drop-in" and locked in place by the nozzle. This design creates a fixed relationship between the tip and nozzle, ensuring consistent stick-out and superior gas coverage. The tapered base of the contact tip improves electrical conductivity and heat dissipation, significantly extending consumable life and reducing downtime.

Compatibility and Setup

This model is outfitted with a Miller-style power pin, making it a direct plug-and-play replacement for standard Miller MIG guns. It is pre-lined and configured for .045" (1.2mm) welding wire, a common size for structural steel and heavy plate welding. The gun features a comfortable curved handle and a standard trigger, designed to minimize hand stress during prolonged use. The 45-degree neck offers excellent access to joints while maintaining a comfortable welding angle.

Durability and Maintenance

Bernard Q-Guns are built to last. The cable assembly is protected by a rugged outer jacket that resists abrasion, cuts, and burns. Maintenance is simplified thanks to the modular design; the neck, handle, and trigger can be serviced or replaced independently. Whether you are welding in a shipyard, a trailer manufacturing plant, or a general fabrication shop, the Bernard Q300 delivers the reliability and performance professional welders demand.
