K4360-1 - Lincoln Magnum PRO 100SG Aluminum Spool Gun 8-Pin

Reliable Aluminum Welding Made Easy

Unlock the full potential of your Lincoln Electric welder with the Magnum PRO 100SG Spool Gun, the most cost-effective and reliable way to start welding aluminum. If you have ever tried to push soft aluminum wire through a standard MIG torch, you know the frustration of constant jamming and birdnesting. The Magnum PRO 100SG solves this problem instantly by placing the wire spool directly on the gun, pushing the wire only a few inches. This design guarantees smooth, uninterrupted feeding, allowing you to lay down professional-quality aluminum beads without the headache of downtime or equipment jams.

Lightweight and Ergonomic Design

Welding can be physically demanding, but the Magnum PRO 100SG is designed to keep you comfortable. Weighing in at just 3.5 lbs (1.6 kg), this spool gun is incredibly lightweight, reducing hand and wrist fatigue during long welding sessions. The handle is ergonomically balanced to fit naturally in your hand, giving you precise control over the torch angle and travel speed. The full-travel mechanical trigger offers excellent feedback, so you can feel exactly when the arc engages, even while wearing heavy-duty welding gloves. It is the perfect tool for both occasional DIY projects and experienced fabricators looking for a portable aluminum solution.

Premium Performance and Durability

This isn't just a basic accessory; it is built with Lincoln's premium Magnum PRO technology. The gun utilizes Copper Plus contact tips, which are designed with a larger mass to dissipate heat more effectively than standard tips. This prevents the wire from fusing to the tip and extends the life of your consumables, saving you money in the long run. The long-life diffusers feature Anti-Seize threads, ensuring that maintenance is quick and frustration-free. Whether you are repairing a boat, working on an aluminum trailer, or fabricating custom parts, this gun delivers consistent performance you can trust.

Complete Ready-to-Weld Package

The K4360-1 comes as a complete, ready-to-weld kit. Inside the sturdy protective carrying case, you will find everything you need to get started: the spool gun with a 10-foot cable, a spool of 4043 aluminum wire, a drive roll, and spare contact tips. The 8-pin connector plugs directly into compatible machines like the POWER MIG 140 MP without requiring expensive adapters or bulky control boxes. It is a true plug-and-play solution that transforms your multi-process welder into a dedicated aluminum fabrication station.
