OVERVIEW

High-Performance Replacement MIG Gun for Miller Systems

The Powerweld P3-15M is a robust 300-amp air-cooled MIG gun designed specifically to bridge the gap between Miller power sources and Tweco-style consumables. Engineered for professional industrial environments, this torch features a direct-connect Miller back end, making it fully compatible with a wide range of Millermatic machines and Miller wire feeders that utilize the standard Miller pin configuration. The 15-foot cable assembly offers extended reach, allowing welders to navigate around large workpieces without constantly repositioning the power source.

At the core of the P3-15M is its compatibility with the industry-standard Tweco #3 (14 Series) consumables. This design choice ensures that replacement contact tips, nozzles, and gas diffusers are not only widely available but also cost-effective compared to proprietary OEM parts. The gun is rated for a 60% duty cycle at 300 amps when using CO2 shielding gas, making it suitable for medium-to-heavy fabrication tasks involving mild steel, stainless steel, and flux-cored applications.

Construction-wise, the P3-15M utilizes high-quality copper stranding within the power cable to ensure efficient current transfer and minimal heat buildup. The outer cable jacket is crafted from abrasion-resistant rubber, protecting the internal gas hose and control leads from the harsh environment of a welding shop. The handle features an ergonomic design with a comfortable trigger geometry, reducing hand stress during prolonged welding sessions. A ball-and-socket joint at the handle base provides superior flexibility and strain relief, preventing cable failure at the most critical stress point.

This gun comes ready to weld out of the box, pre-fitted with a standard liner, tip, and nozzle. It is an ideal solution for fabrication shops looking to standardize their consumables inventory while maintaining compatibility with their fleet of Miller welding equipment.

FAQ

Yes, provided your machine uses the standard Miller back-end connection, this gun is a direct fit for the Millermatic 252 and similar models.

The P3-15M uses standard Tweco 14 Series (also known as #3 style) contact tips, nozzles, and gas diffusers.

This is an air-cooled MIG gun rated for 300 amps.

Yes, but you will need to replace the installed steel liner with a polymer or Teflon liner to prevent wire shaving and feeding issues with soft aluminum wire.

The gun is rated at 300 Amps at 60% duty cycle when using CO2 gas. The rating may be slightly lower when using mixed gases like Argon/CO2.

Yes, the gun comes pre-installed with a standard steel wound liner suitable for steel wires.

Simply unscrew the nozzle, then unscrew the old contact tip from the gas diffuser and screw in the new one. It uses standard threaded Tweco style tips.
