K639-6 - Lincoln UNM Aluminum Suction Nozzle for Heavy Smoke Extraction

Clear the Air with the Lincoln UNM Heavy Smoke Nozzle

When you are laying down heavy beads and generating thick clouds of smoke, a standard fume nozzle just doesn't cut it. That is where the Lincoln Electric K639-6 UNM Suction Nozzle comes in. Built specifically for "heavy smoke" applications, this 8-inch aluminum nozzle acts like a vacuum for your weld plume, sucking away hazardous fumes before they reach your breathing zone. It is the perfect upgrade for your Lincoln X-Tractor 1GC system, giving you the extra coverage you need for flux-cored wire, stick welding, or oily base metals.

One of the biggest hassles with fume extraction is keeping the nozzle in the right spot. If it's too far away, it doesn't work; if it's hard to move, you won't use it. The K639-6 solves this with a sturdy magnetic stand. You can snap it onto your workbench, a steel column, or the workpiece itself, keeping the suction head right where the action is. The magnet is strong enough to hold the nozzle steady but allows for quick adjustments as you move along a joint.

Durability is key in any shop, and this nozzle is made from tough aluminum that can handle the heat and sparks of daily fabrication. It comes ready to work with an included adapter that fits standard 1-3/4 inch hoses, so you can get set up quickly. By keeping the nozzle within 4 inches of your arc, you ensure maximum smoke removal, keeping your helmet lens cleaner and your lungs happier. Whether you are in shipbuilding, heavy fabrication, or automotive repair, this nozzle helps you focus on the weld, not the smoke.
