P4-15LPW - Parker P4 400A MIG Gun for Lincoln PowerMIG - 15ft, Tweco Style

Heavy-Duty 400A MIG Gun with Lincoln PowerMIG Connection

The Parker P4 Series MIG Gun (P4-15LPW) is a robust welding torch designed to deliver consistent, high-amperage performance. Rated at 400 Amps with CO2 and 350 Amps with Mixed Gas at a 60% duty cycle, this air-cooled gun is capable of handling heavy-duty welding applications where heat management and durability are critical.

This specific model is configured with a Lincoln PowerMIG back-end connection, ensuring a perfect mechanical and electrical fit for Lincoln Electric PowerMIG series welders. The direct-connect design ensures optimal conductivity and gas flow, preventing the leaks and voltage drops often associated with universal adapters.

Technical Specifications & Build

The P4-15LPW features a 15-foot (4.6m) cable encased in a durable, abrasion-resistant jacket that withstands the rough conditions of a shop floor. The gun is designed to run wire diameters ranging from 0.030" (0.8mm) up to 5/64" (2.0mm), providing the versatility needed for both light-gauge sheet metal and heavy plate welding.

Maintenance is simplified thanks to the Tweco #4 style front end. Welders can easily source and replace contact tips, gas diffusers, and nozzles from any standard welding supplier. The gun comes ready to weld with a standard steel liner pre-installed. For aluminum applications, the liner can be easily swapped for a polymer or Teflon option.

Key features include:

• High Duty Cycle: 60% at 400A allows for long weld runs without overheating.
• Rugged Construction: Impact-resistant handle and heavy-duty cable assembly.
• Smooth Feeding: Optimized liner and cable geometry reduce friction for consistent wire delivery.

If you are looking for a reliable, high-performance alternative to your OEM Lincoln gun that uses economical Tweco parts, the Parker P4-15LPW is the professional's choice.
