P4E312M - Parker Style 300A MIG Gun with Miller Connection - 12ft

Industrial Grade 300A MIG Welding Gun

The P4E312M is a robust 300-amp air-cooled MIG gun designed to meet the rigorous demands of industrial fabrication and manufacturing. Engineered by Parker Torchology, this gun features a direct Miller-style backend connection, ensuring seamless compatibility with a vast array of Miller wire feeders and integrated power sources. The 12-foot cable assembly provides an ideal balance between operational reach and consistent wire feeding performance, minimizing the friction that can lead to bird-nesting or erratic arcs.

Constructed with high-quality materials, the torch utilizes a "Parker Style" ergonomic handle that fits comfortably in the operator's hand, significantly reducing fatigue during long welding shifts. The cable is reinforced with durable outer sheathing and articulated strain reliefs at both the gun and machine ends, protecting the internal power cable and liner from acute bending and wear. This attention to structural integrity ensures a long service life even in harsh shop environments.

A key technical advantage of this model is its front-end configuration, which is designed to accept Bernard Centerfire style consumables. This industry-standard consumable system is renowned for its excellent gas coverage and ease of changeover, allowing for tool-free nozzle and tip replacements. By utilizing widely available consumables, the P4E312M simplifies inventory management and reduces downtime associated with parts sourcing. Rated for 300 amps at a 60% duty cycle using CO2, this gun is perfectly suited for medium-to-heavy structural steel work, fabrication, and maintenance applications.
