OVERVIEW

Industrial Grade 300 Amp MIG Gun for Miller Feeders

The Bernard Q300 MIG Gun (SKU: BQ3012AE4IMC) is a premier choice for industrial fabrication environments requiring a robust, air-cooled welding torch. Engineered to withstand the rigors of heavy manufacturing, this 300-amp gun features a 12-foot cable assembly, offering a precise balance between operator reach and consistent wire feeding performance. It is terminated with a direct Miller connection, making it immediately compatible with a wide range of Miller industrial wire feeders and power sources without the need for adapters.

At the core of the Q-Gun's performance is 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. This design ensures excellent electrical conductivity and heat dissipation, resulting in longer consumable life and more stable arcs. The nozzle itself features a built-in spatter shield, protecting the gas diffuser and ensuring smooth gas flow for high-quality weld deposits.

Operator comfort and efficiency are addressed through the gun's ergonomic handle and rotatable neck. The neck can be adjusted without tools, allowing welders to orient the torch for optimal access to complex joints. The heavy-duty cable is reinforced to resist abrasion and heat, ensuring longevity in harsh shop environments. For maintenance and repair operations (MRO) and production welding alike, the Bernard Q300 delivers reliable, continuous performance at a 100% duty cycle with CO2 shielding gas.
