301121001 - Miller Suitcase 12 RC Wire Feeder with Gas Timers & Burnback

Advanced Portable Wire Feeding for Industrial Applications

The Miller Suitcase 12 RC (SKU: 301121001) is a specialized configuration of Miller's legendary portable wire feeder, designed for the most demanding industrial environments. Unlike standard voltage-sensing feeders, this "RC" (Remote Control) model connects directly to your power source via a 14-pin control cord, allowing the operator to adjust voltage and wire feed speed directly at the feeder. This specific unit is factory-equipped with advanced process controls, including a 3-second pre-flow and 5-second post-flow gas timer, ensuring optimal shielding gas coverage before the arc strikes and after it extinguishes. This is critical for high-quality applications involving stainless steel or aluminum where atmospheric contamination must be minimized.

Rugged Durability Meets Precision Control

Built to withstand the harshest job sites, the Suitcase 12 RC features a totally enclosed, impact-resistant, and flame-retardant case. This design ensures that the internal drive mechanism and wire spool are completely protected from dirt, moisture, and metal shavings, significantly extending the life of the unit. The heavy-duty drive motor is engineered to deliver consistent torque, easily feeding wire diameters up to 5/64 inch (2.0 mm). This model also includes a Burnback control feature, which adjusts the time the welding wire remains hot after the trigger is released, preventing the wire from sticking to the weld puddle or the contact tip.

Enhanced Operator Comfort and Efficiency

For welders performing long, continuous welds, this unit includes a Trigger Hold (Th) function. This allows the operator to release the gun trigger while continuing to weld, reducing hand fatigue during extended operation. The digital meters on the front panel provide clear, accurate readings of wire feed speed and voltage, ensuring that weld parameters are maintained within procedure specifications. Whether you are working in shipbuilding, heavy construction, or field fabrication, the Miller Suitcase 12 RC with its specialized gas and burnback controls offers the reliability and precision required for code-quality work.

Compatibility and Performance

This feeder is designed to work with Miller power sources that supply 24 VAC auxiliary power through a 14-pin receptacle. It supports both Constant Current (CC) and Constant Voltage (CV) output types, making it versatile for various welding processes including MIG (GMAW) and Flux-Cored (FCAW). The 12-inch spool capacity accommodates up to 45 lbs of wire, reducing downtime for spool changes. With its ergonomic handle and lightweight design (relative to its capacity), it is easily transported around complex job sites.
