OVERVIEW

Master High-Amperage Welding

Take your welding capabilities to the next level with the Tweco© FUSION PRO™ 7W Water Cooled MIG Gun. Designed for professional welders who refuse to compromise on power or comfort, this beast of a torch is rated for a massive 500 Amps at 100% duty cycle. Say goodbye to overheating guns and frequent cool-down breaks. The superior water-cooling technology keeps the front-end components and handle cool, ensuring you can keep laying down beads shift after shift without interruption.

Superior Comfort and Control

Welding at high amperages is tough work, but your equipment shouldn't make it harder. The Fusion Pro 7W features a thoughtfully designed ergonomic handle that fits naturally in your hand, reducing grip fatigue. The soft-touch over-molding provides a secure grip even with heavy welding gloves, while the flexible 12-foot cable allows you to move freely around your workspace. The patented knuckle joint at the handle base relieves tension on your wrist, giving you the control you need for precision welds.

The Velocity™ Advantage

Experience the difference of Tweco's Velocity™ consumables. This gun uses a revolutionary threadless contact tip system that locks in place for perfect alignment and better electrical contact. This means you get a smoother, more stable arc and fewer burn-backs. Changing tips is faster and easier than ever—no threads to cross or seize up. This model is set up for 1/16" wire and features a direct connection for Miller© wire feeders, making it the perfect upgrade for your high-output welding setup.

Built for the Toughest Jobs

From shipyards to heavy equipment repair, the Fusion Pro 7W is built to survive. The durable outer jacket protects the water and power lines from sparks, abrasion, and hot surfaces. If you are looking for a water-cooled MIG gun that delivers consistent, high-quality results and stands up to daily abuse, the Tweco Fusion Pro 7W is the tool you can trust to get the job done right.
