300371 - Miller Spoolmate 100 MIG Spool Gun 135A 12ft Cable

Reliable Aluminum Welding with the Miller Spoolmate 100

The Miller Spoolmate 100 Spool Gun (300371) is a highly reliable and economical solution designed specifically for light industrial aluminum welding applications. Engineered by Miller Electric, this spool gun is the perfect accessory for welders looking to achieve smooth, consistent feeding of aluminum wire without the common issues associated with standard MIG guns. With a welding output rating of 135 Amps at a 30% duty cycle, it provides ample power for a variety of fabrication and repair tasks.

One of the standout features of the Spoolmate 100 is its 12-foot (3.7 m) direct connect cable. This extended reach allows operators to access hard-to-reach joints and work around large projects with ease. The cable is reinforced with heavy-duty strain relief to prevent kinking and ensure durability in workshop environments. The gun connects directly to compatible Millermatic and Multimatic power sources, eliminating the need for complex adapters or control boxes.

Feeding aluminum wire requires precision, and the Spoolmate 100 delivers with its dual V-knurled drive rolls. These rolls grip the soft aluminum wire securely, ensuring consistent feeding and preventing bird-nesting. The adjustable drive roll tension lever allows users to fine-tune the pressure for different wire types, while the adjustable pressure lever makes loading and unloading wire quick and hassle-free. Additionally, the clear spool canister protects the wire from contaminants while allowing the operator to easily check the remaining wire supply at a glance.

Durability is key in any welding equipment, and this spool gun features a heavy-duty drive motor and a cast-aluminum gearbox designed for a long service life. The recessed contact tip design is another thoughtful addition, making welding easier by improving visibility and preventing burn-back issues. Whether you are working on aluminum fabrication, home maintenance, or automotive repair, the Miller Spoolmate 100 is an essential tool for achieving high-quality welds.
