K3133-2 - Lincoln Magnum PRO 450 Dual Procedure MIG Gun, 15ft, 450A

Comfort and Control for the Professional Welder

Welding at high amperages all day takes a toll on your body, which is why the Lincoln Electric Magnum® PRO 450 Dual Procedure MIG Gun is designed with the welder's comfort as a priority. The K3133-2 features the signature Comfort Grip™ handle, a barrel-style design that is lightweight and perfectly balanced. This ergonomic shape reduces wrist strain and fatigue, allowing you to maintain precision and control throughout long shifts. Whether you are welding in flat, horizontal, or out-of-position angles, the gun feels natural in your hand.

Switch Settings on the Fly

Stop walking back and forth to your feeder. The "Dual Procedure" switch integrated into the handle puts control right at your fingertips. If your machine supports it, you can toggle between two pre-set welding modes instantly. This is perfect for tacking vs. welding, or switching between a hot pass and a fill pass without breaking your rhythm. It’s a massive time-saver that keeps your hood down and your arc on.

Built to Last, Easy to Maintain

Nothing is more frustrating than a contact tip that seizes in the diffuser or a gun neck that wobbles. The Magnum PRO 450 solves these common headaches. The Anti-Seize™ threads on the tips and diffusers are designed to prevent them from fusing together, even after hours of high-heat welding. The Secure-Lock™ gun tube keeps the neck rigid and prevents it from rotating unexpectedly. Plus, with the Copper Plus® contact tips, you get better heat transfer and longer life, meaning fewer tip changes and smoother arc starts.

100% Duty Cycle Reliability

When the job demands heavy flux-cored or spray transfer MIG welding, you need a gun that won't overheat. Rated at 450 amps at 100% duty cycle using CO2 or mixed gas, this gun can handle whatever you throw at it. The 15-foot cable gives you the reach you need to work around large assemblies without constantly moving your wire feeder. Upgrade to the Magnum PRO 450 and experience the difference that industrial-grade engineering makes in your daily work.
