20002169 - Tweco 35K-174C Mini-MIG Gun Adapter Kit for Lincoln Welders

Upgrade Your Lincoln Welder with Tweco Performance

If you own a Lincoln SP-series or Weld-Pak welder and are looking to improve your welding experience, the Tweco 35K-174C Mini Gun Conversion Kit is the perfect solution. Many welders prefer the ergonomics, durability, and consumable availability of Tweco MIG guns over the stock guns provided with compact welding machines. This conversion kit bridges the gap, allowing you to equip your trusty Lincoln power source with a high-quality Tweco Mini-MIG gun.

Why Convert?
Stock guns can sometimes be bulky, stiff, or difficult to find parts for locally. By converting to a Tweco Mini-MIG gun using this adapter kit, you gain access to the industry-standard Tweco consumable line (11-series tips, 21-series nozzles). These parts are available at virtually every welding supply store, ensuring you are never stuck waiting for a shipment to finish a job. Additionally, Tweco guns are renowned for their comfortable handle design and flexible cable assemblies, which reduce wrist fatigue during long welding sessions.

Seamless Compatibility
The 35K-174C kit is designed specifically for Lincoln machines like the SP-100, SP-135, SP-175, and Weld-Pak models. It replaces the back-end connection of the Tweco gun to plug directly into your Lincoln's wire drive. The kit includes everything you need for the conversion: the brass power pin that slides into the drive rolls, the gas hose connection, and the trigger wires. Once installed, the connection is secure and reliable, providing consistent wire feeding and arc stability.

Easy Installation
Installing the conversion kit is a straightforward process. It involves opening the handle case at the rear of your Tweco Mini-MIG gun and replacing the existing connector with the components from this kit. No permanent modification to your welding machine is required, meaning you can always switch back if needed. Whether you are a hobbyist working on automotive restoration or a professional doing light fabrication, this adapter kit unlocks the full potential of your Lincoln welder by pairing it with the legendary performance of a Tweco gun.
