K2752-5 - DownFlex 400-MS/A Auto-Start Motion Sensor Kit

Hands-Free Fume Extraction Convenience

Take the hassle out of shop safety with the Lincoln Electric K2752-5 Motion Activated Start/Stop Sensor. Designed specifically for the DownFlex 400-MS/A downdraft table, this smart accessory acts as an automated assistant for your welding station. In a busy fabrication environment, it is easy to forget to flip the switch on your fume extractor before striking an arc, or to leave it running loudly while you are prepping the next piece. The K2752-5 solves both problems by watching your workspace for you.

The sensor mounts conveniently out of the way on the back panel of your table, keeping your work area clear while monitoring for movement. As soon as you move your hands, torch, or workpiece over the grid, the sensor detects the motion and instantly powers up the downdraft fan. You get immediate fume protection without ever having to touch a button or remove your welding gloves. It allows you to focus entirely on your weld, knowing that your breathing zone is being protected automatically.

Beyond just turning the fan on, this device is smart enough to know when to turn it off. It features a built-in "run-out" timer that keeps the fan spinning for a short period after you stop moving. This is crucial because smoke often lingers for a few seconds after the arc is extinguished. The timer ensures all that residual smoke is pulled down and filtered out before the unit goes into standby mode. This keeps your shop air clean and prevents the machine from cycling on and off too rapidly.

Adding the K2752-5 to your setup is a quick way to upgrade your shop's efficiency. It connects easily with a cable to the back of your table, making installation a breeze. By automating your fume extraction, you save on electricity bills, reduce the constant drone of the fan when you aren't welding, and extend the life of your equipment's motor and filters.
