Welding safety goes beyond just helmets and gloves; it starts with the air you breathe. The Lincoln Electric SHFA Flat Suction Nozzle (K639-5) is an essential addition to your shop's safety gear, designed to work seamlessly with the X-Tractor 1GC system to pull harmful welding fumes away from your breathing zone. Whether you are working on a custom automotive project or tackling heavy structural repairs, this suction head gives you the control you need to keep your workspace clear and your lungs protected.
Every weld joint is different, and your fume extraction needs to adapt. The K639-5 features a 20-inch flexible steel hose that stays where you put it. You can bend, twist, and angle the nozzle to get right next to the arc without it drooping or getting in your way. The 6-inch aluminum flat nozzle is shaped to maximize suction velocity, effectively capturing smoke when placed within the recommended 4-inch range. Because it is made of aluminum and steel, you don't have to worry about it melting if it gets close to the heat, making it a tough companion for daily welding tasks.
Stop fighting with clamps or trying to prop up your exhaust hose. This unit comes with a powerful magnetic stand that snaps securely onto your welding table or the steel part you are welding. This means you can reposition the suction head in seconds as you move along a seam. It is all about convenience and efficiency—letting you focus on laying the perfect bead rather than adjusting your equipment. The included hose-to-tube adapter (S20591-7) ensures a tight fit with standard 1-3/4 inch hoses, so you don't lose suction power due to leaks.
Investing in proper fume extraction accessories like the SHFA nozzle helps reduce downtime caused by smoke accumulation and improves overall visibility of the weld puddle. It is a smart choice for:
