951599 - Miller SuitCase 12RC Wire Feeder Package with Bernard BTB 300A Gun

Industrial-Grade Portable Wire Feeder Package

The Miller SuitCase 12RC (951599) is a heavy-duty, portable wire feeder designed for demanding industrial environments where reliability and performance are paramount. This specific package configuration includes the Bernard™ BTB 300A MIG gun and is equipped with advanced control features including a 3-second preflow, 5-second postflow, trigger hold, and burnback control. The unit operates on 24 VAC control voltage, making it compatible with Miller power sources that provide 14-pin remote control capabilities.

Engineered for consistency, the 12RC features a high-torque drive motor with tachometer control, ensuring wire feed speed remains accurate regardless of load variations or cable orientation. The wire drive system utilizes ultra-low drag inlet guide pins to prevent wire deformation and ensure smooth feeding of both solid and flux-cored wires. The feeder is rated for a substantial 500 amps at 100% duty cycle, providing ample headroom for high-amperage applications, although the included gun is rated for 300 amps.

The external construction is as robust as the internal mechanics. The case is manufactured from impact-resistant, flame-retardant material that is totally enclosed to protect the welding wire and internal components from moisture, dust, and contaminants. The design includes built-in slide rails for easy positioning and a door that opens vertically or horizontally for convenient wire spool changes. Digital meters with SunVision™ technology allow operators to monitor voltage and wire feed speed (and amperage with compatible power sources) clearly, even in direct sunlight.
