10461128 - Tweco Smoke Master 450A Fume Extraction Gun, 15ft, Miller Style

Breathe Easier and Weld Longer

Welding generates smoke, and breathing it in all day takes a toll. The Tweco® Smoke Master® 450 Amp MIG Gun is your first line of defense against hazardous welding fumes. By capturing up to 90% of the smoke right at the nozzle—before it ever reaches your helmet—this gun dramatically improves the air quality in your personal breathing zone. It’s not just about safety; it’s about comfort. With the smoke cleared away instantly, you get a better view of the puddle, allowing for more precise welds and less eye irritation over the course of a shift.

We know that fume guns have a reputation for being heavy and bulky, but Tweco has designed the Smoke Master to be as welder-friendly as possible. The handle is ergonomically shaped to fit naturally in your hand, and the trigger is extended to accommodate different grip styles, reducing the hand cramping that often comes with heavy-duty guns. The 15-foot cable is wrapped in a high-quality leather jacket. This isn't just for looks; the leather slides easily over worktables and parts, preventing the snagging and dragging that can make other vacuum hoses a nightmare to manage. Plus, it stands up to hot sparks and spatter far better than plastic sheathing.

Control is right at your fingertips. Sometimes, full vacuum power is too much and might pull away your shielding gas, causing porosity. The Smoke Master solves this with a simple slide valve on the handle. You can dial down the suction when you're welding in a corner or dial it up when you're in the open, all without stopping your weld or walking back to the extraction unit. This model is set up for 1/16" wire and plugs directly into Miller® feeders, so you can hook it up and get to work immediately. It’s built for the long haul, with a rugged design that uses the vacuum airflow to help cool the front end, meaning your consumables last longer even when you're pushing 450 amps.

Whether you are running flux-cored or solid wire in spray transfer, this gun handles the heat. The air-cooled design means you don't have to fuss with water coolers and leaky hoses, yet it delivers the high-amperage performance you need for thick plate. Upgrade your setup to the Smoke Master and experience the difference of welding in clean air.
