Built for the Welder

Lincoln Electric understands that comfort equals productivity. The Magnum PRO 550 features the signature Comfort Grip design, a lightweight, balanced handle that fits naturally in the hand to reduce fatigue. The gun is also designed for easy maintenance; the PRO Select Gun Selection System ensures you have the right tool for the amperage, while the Anti-Seize tip and diffuser threads prevent parts from fusing together. The included Copper Plus contact tips offer superior heat dissipation, lasting longer than standard tips and saving you money on consumables over time. Upgrade to the Magnum PRO 550 for a welding gun that works as hard as you do.
