MK Products Prince® XL Spool Gun: Maximum Control for Aluminum & Beyond

When it comes to aluminum welding — especially on jobs where consistency, control, and mobility matter — a spool gun can make all the difference. The Prince® XL Spool Gun from MK Products is widely regarded as one of the most versatile pistol-grip spool guns on the market, trusted by fabricators, maintenance teams, and production welders alike.

Designed for flexibility, durability, and compatibility across power supplies, the Prince XL delivers smooth wire feeding and excellent arc control for aluminum, stainless, steel, and flux-cored applications.

What Makes the Prince® XL Spool Gun Stand Out?

Lightweight, Ergonomic Design

The Prince XL features a compact pistol-grip design weighing under 3 pounds, helping reduce fatigue during extended weld sessions. Whether you’re welding overhead, reaching into tight spaces, or working on aluminum repair jobs, the balance and feel of this gun matter.

Spool Flexibility Built In

Unlike many spool guns, the Prince XL accepts both 1 lb and 2 lb wire spools, giving you flexibility based on job size and material requirements — less downtime, less wire waste.

Power Supply Compatibility Made Simple

One of the biggest advantages of the Prince XL is its adaptability. It can be connected to virtually any CV or CC power supply using the WC-1 Spool Gun Control or MK Products’ manufacturer-specific interface cables.

Available adapter options support major power sources, including:

• Lincoln Electric

• Miller Electric

• ESAB

• Thermal Arc

• Panasonic

This makes the Prince XL an excellent choice for shops running mixed equipment brands.

EZ-Lock® 360° Rotating Barrels

The Prince XL uses EZ-Lock® rotating barrels that allow full 360° rotation for better torch positioning. Available barrel options include:

Expandable & Convertible Design

The Prince XL isn’t just a spool gun — it’s a system. It can be:

• Converted to a push-pull gun when paired with a Cobramatic® cabinet and 12” wire spool

• Extended with a 25 ft control cable kit for greater working range

This modular design makes it ideal for growing shops and evolving production needs.

• Contact tips (standard & spring-loaded)
