CF99921 - Crossfire Trion 250 Aluminum Spool Gun

Expand Your Welding Capabilities with the Crossfire Spool Gun

The Crossfire Spool Gun (CF99921) is the definitive accessory for owners of the Crossfire Trion 250 who need to tackle aluminum welding projects. While standard MIG guns are excellent for steel and stainless steel, they often struggle with aluminum wire. Aluminum is soft and pliable, making it prone to buckling, kinking, and "bird-nesting" when pushed through a standard 10 or 15-foot liner. This spool gun solves that problem entirely by relocating the wire spool directly to the gun itself, reducing the feed distance to mere inches.

Precision Control and Performance

Designed for seamless integration, this spool gun plugs directly into the Crossfire Trion 250, requiring no complex modifications. It features a convenient wire speed control dial located right on the handle, allowing operators to fine-tune their settings on the fly without returning to the machine. This is particularly useful when welding in out-of-position scenarios or when moving around large workpieces. The gun is rated for the output of the Trion 250, ensuring consistent arc stability and penetration on aluminum plates and extrusions.

Built for the Fabricator

Whether you are repairing aluminum trailers, fabricating custom automotive parts, or working on marine applications, the CF99921 delivers professional results. It accepts standard 4-inch wire spools (typically 1lb or 2lb), which are widely available in common alloys like 4043 and 5356. The transparent spool cover allows you to keep an eye on your wire supply, preventing unexpected run-outs in the middle of a critical weld. Ergonomically designed, the handle provides a comfortable grip that helps minimize hand fatigue during long welding sessions.

Key Benefits

• Eliminates Feeding Issues: The short feed path prevents soft aluminum wire from jamming.


• Plug-and-Play: specifically engineered for the Trion 250 connection points.


• Versatile: Can also be used for mild steel or stainless steel when a different wire type is needed quickly without changing the main machine spool.
