K2704-3 - Lincoln Cougar 300A Air-Cooled Push-Pull Gun, 50ft Cable

Master Aluminum Welding with Comfort and Control

Take your aluminum welding projects to the next level with the Lincoln Electric Cougar™ Push-Pull Gun (K2704-3). Designed for welders who prefer the upright feel of a pistol-grip handle, this gun combines ergonomic comfort with industrial-grade performance. Whether you are welding boat hulls, trailers, or custom aluminum fixtures, the 50-foot cable gives you the freedom to move around large workpieces without restriction, ensuring you can reach every joint with ease.

Ergonomic Design for All-Day Use

Welding fatigue can compromise weld quality, which is why the Cougar features the Sure-Grip™ handle. Lightweight and perfectly balanced, it fits comfortably in either the left or right hand, allowing for steady manipulation of the torch. The integrated strain relief system flexes with your movements, reducing wrist strain and protecting the internal wiring from sharp bends. The recessed trigger design prevents accidental arcing when setting the gun down, adding an extra layer of safety and durability to your daily operations.

Superior Consumables and Convenience

The Cougar K2704-3 is built to keep you welding longer. It utilizes Lincoln's Copper Plus™ contact tips, which are designed with a larger diameter to dissipate heat more effectively than standard tips, resisting burn-back and extending consumable life. When it is time to swap out parts, the tool-less drive roll system makes changeovers a breeze. The slip-fit dual-groove drive rolls feature a unique D-contour that locks them in place, preventing unwanted spinning. With the Cougar, you get a premium, hassle-free welding experience that delivers professional results on every bead.
