CL3015TJ5CMC - 300A Bernard Style MIG Gun for Miller Feeders - 15ft Cable

Industrial Grade 300A MIG Gun for Miller Feeders

The CL3015TJ5CMC is a high-performance 300 Amp MIG welding gun designed to serve as a direct replacement or upgrade for welding systems utilizing Miller wire feeders. Engineered for durability and consistent performance, this air-cooled gun features a 15-foot cable assembly, providing ample reach for medium-to-heavy fabrication tasks in industrial environments. The unit is rated for 300 Amps at a 60% duty cycle when using CO2 shielding gas, making it suitable for structural steel, heavy equipment manufacturing, and general fabrication applications.

Bernard Centerfire Compatibility

A key technical advantage of this assembly is its utilization of Bernard Centerfire style consumables. The Centerfire system is renowned in the industry for its 'drop-in' contact tip design, which eliminates the need for tools during tip changes and ensures a fixed contact tip position for consistent arc starts. The nozzle includes a built-in spatter shield that protects the gas diffuser and ensures smooth gas flow, reducing turbulence and porosity in the weld pool. This gun comes pre-configured with these high-efficiency consumables, allowing for immediate integration into existing workflows that standardize on Centerfire parts.

Robust Construction and Ergonomics

The gun is constructed with a rugged outer jacket designed to withstand the rigors of the shop floor, including resistance to abrasion, hot sparks, and incidental impact. The handle is ergonomically contoured to fit comfortably in the operator's hand, reducing grip fatigue during long weld seams. A heavy-duty strain relief at both the feeder and handle ends prevents cable kinking and protects internal copper stranding from breakage. The Miller-style back-end plug ensures a secure, leak-free connection to the wire feeder, maintaining optimal electrical conductivity and shielding gas delivery.
