75144302-I - American Weldquip 7/16" Tapered MIG Nozzle with Built-In Insulator

Precision Engineered for American Weldquip Systems

The American Weldquip 75144302-I Nozzle is a premium OEM consumable designed specifically for American Weldquip 300 Amp and 400 Amp MIG guns. Engineered to meet the rigorous demands of industrial welding, this nozzle features a 7/16-inch bore with a tapered profile. The tapered shape is essential for welders who require enhanced visibility of the weld pool or need to access tight corners and confined spaces where standard cylindrical nozzles cannot reach.

A standout feature of this model is the built-in insulator. Unlike traditional nozzle assemblies that require a separate insulator piece, the 75144302-I integrates the insulation directly into the nozzle body. This design innovation simplifies inventory management, reduces the risk of losing small parts during changeovers, and ensures a consistent, secure fit every time. The integrated insulator also provides excellent dielectric strength, preventing electrical arcing to the nozzle wall.

The nozzle is designed with a recessed tip relationship. By positioning the contact tip slightly back inside the nozzle, the design offers superior protection against spatter buildup bridging the gap between the tip and the nozzle. This configuration is particularly beneficial for higher amperage welding where spatter generation can be significant, helping to extend the life of your contact tips and reducing downtime for cleaning.

Constructed from high-grade copper alloy, this nozzle delivers optimal thermal conductivity, effectively dissipating heat to prevent overheating during long duty cycles. Whether you are fabricating structural steel or performing precision automotive work, the American Weldquip 75144302-I ensures reliable gas coverage and arc stability.
