401-6-75 - Tregaskiss 401-6-75 Heavy Duty MIG Nozzle, 3/4" Bore, 1/8" Recess

Optimize Your Arc with Superior Gas Coverage

For professional welders, the front-end consumables of a MIG gun are critical to achieving a stable arc and a clean weld. The Tregaskiss 401-6-75 Nozzle is a heavy-duty solution designed for welders who demand the best from their equipment. With a generous 3/4-inch bore, this nozzle excels in applications requiring high deposition rates and high amperage. The wide bore ensures that the weld pool is completely blanketed by shielding gas, significantly reducing the chance of porosity and oxidation, even when weaving or welding in less-than-ideal positions.

Durability is at the core of the 401-6-75 design. Constructed from high-quality copper alloy, it resists the adhesion of weld spatter, making cleaning easier and less frequent. The heavy-duty classification means the walls are thicker and more robust, capable of absorbing and dissipating the intense heat generated during prolonged welding cycles. This thermal management helps prevent the nozzle from overheating and deforming, a common issue with lighter-duty alternatives. For the welder, this translates to fewer interruptions for nozzle changes and more time spent laying beads.

The 1/8-inch tip recess is another feature that enhances the welding experience. By positioning the contact tip slightly back from the nozzle edge, the tip is shielded from the immediate splash of the weld puddle. This recess is particularly useful for spray transfer modes or when using flux-cored wires where spatter can be aggressive. It also allows the welder to maintain a proper stick-out while keeping the nozzle at a comfortable distance from the joint. This balance of protection and visibility makes the 401-6-75 a favorite among professionals using Tregaskiss guns.

At Welders Supply, we understand that quality consumables lead to quality welds. This genuine Tregaskiss nozzle fits securely onto your MIG gun, ensuring a tight seal for gas delivery and electrical insulation. Whether you are retrofitting a robotic cell or upgrading your handheld torch, the 401-6-75 offers the performance upgrade you need for heavy-duty structural, automotive, or general fabrication work.
