OVERVIEW

Upgrade Your Welding Setup with the Bernard Q300 MIG Gun

Take your welding comfort and reliability to the next level with the Bernard Q300 MIG Gun. Designed for professional welders who demand the best, this 300-amp torch is a direct replacement for many stock guns found on Miller equipment. With a 12-foot cable, it provides just the right amount of reach for shop fabrication, automotive work, and general repairs, ensuring your wire feeds smoothly without the friction issues often associated with longer liners.

One of the standout features of this gun is the Centerfire consumable system. If you are tired of cross-threading contact tips or dealing with burn-backs that fuse the tip to the diffuser, you will love this design. The contact tip simply drops into the diffuser and is secured by tightening the nozzle by hand. This creates a large surface area for electrical transfer, giving you a hotter, more consistent arc and less downtime changing parts. Plus, the rotatable neck lets you change the angle of the torch body to get into tight corners without straining your wrist.

The handle is built to fit naturally in your hand, reducing fatigue during long days under the hood. The trigger is designed to last, capable of withstanding over a million cycles. Whether you are welding mild steel, stainless, or aluminum, the Bernard Q300 (BQ3012AE4IMC) offers the durability and performance you need to lay down perfect beads every time. Simply plug it into your Miller machine, and you are ready to weld.
