137549 - Miller WC-24 Spool Gun Control Box

Upgrade Your Miller Power Source for Aluminum Welding

Expand the capabilities of your existing Miller welder with the WC-24 Weld Control (137549). If you are looking to tackle aluminum projects using a Spoolmatic® or Spoolmatic Pro gun, this control box is the vital link you need. It transforms your standard 14-pin Miller CV power source into a spool gun-ready system, allowing you to feed soft aluminum wire with precision and ease. The WC-24 is designed to be lightweight yet rugged, featuring a non-metallic case that protects the internal electronics without adding unnecessary bulk to your rig.

Optimized Arc Performance

Getting a clean start is half the battle in welding, especially with aluminum. The WC-24 features a built-in potentiometer that gives you control over the wire drive motor's acceleration. This "run-in" control allows you to adjust how fast the wire hits the metal before the arc establishes, helping to prevent burn-backs and stubbing. The result is a smoother, more consistent arc start every time you pull the trigger. This level of control is essential for professional-grade fabrication where weld quality cannot be compromised.

Easy Integration

Designed for convenience, the WC-24 mounts directly onto your power source, keeping your setup organized. It draws 24 VAC power directly from the machine's 14-pin receptacle, eliminating the need for external power supplies. Whether you are running an XMT, a Dimension, or a Trailblazer engine drive, this control unit integrates seamlessly, letting you switch between standard MIG and spool gun operations efficiently. It is the perfect accessory for welders who need versatility in their equipment arsenal.
