OVERVIEW

Breathe Easier While You Weld

Welding safety meets high performance with the Tweco 420C Water-Cooled Fume Extraction Gun. If you are pushing high amps and generating heavy smoke, a standard gun just won't cut it. This water-cooled powerhouse is designed to keep you cool and your breathing zone clear. By extracting fumes right at the nozzle, it prevents smoke from rising into your helmet, providing a clearer view of the puddle and a healthier work environment.

This model comes ready to hook up to your existing equipment with a Miller-style direct plug and a manageable 10-foot cable, perfect for bench work or production cells where long leads aren't necessary. The water-cooling system ensures the handle and nozzle stay cool to the touch, even when you are burning wire all day at 400 amps. Unlike older, bulky fume guns, the Tweco 420C is designed with ergonomics in mind, offering a comfortable grip and a swivel connection to reduce the drag from the vacuum hose.

Don't compromise on your health or your weld quality. The Tweco 420C uses the rugged consumables you already trust, so you get the same reliable arc start and wire feeding you expect from Tweco. It is the ideal upgrade for professional welders looking to reduce smoke exposure without slowing down production.
