K1669-4 - Lincoln Electric Arc Sensor and Lamp Kit for Statiflex/Prism 115V

Hands-Free Fume Control and Better Visibility

Focus on your weld, not your equipment, with the Lincoln Electric K1669-4 Arc Sensor and Lamp Kit. Designed for welders using the Statiflex 400-MS or Prism 2400 systems, this kit takes the hassle out of managing your fume extractor. We all know the drill: you get set up, drop your hood, strike an arc, and then realize you forgot to turn on the extractor. With this kit installed, that problem disappears. The built-in arc sensor detects the flash of your arc the instant you start welding and automatically kicks the fan into high gear.

It doesn't just turn on; it knows when to turn off. After you stop welding, the fan keeps running for exactly 50 seconds to suck away those lingering fumes that hang around the hot weld pool, keeping your breathing zone clear. Once the air is clean, it shuts down automatically, saving you from the constant drone of the fan when you are fitting up or checking prints. It’s the kind of convenience that makes a long shift just a little bit smoother.

But it's not just about the fan. This kit also upgrades your extraction arm with a powerful hood-mounted lamp. Good lighting is half the battle in producing quality welds, and having a light source positioned right above your work area—integrated into the extraction hood you are already positioning—means you can see your joint clearly without fighting with stand lights or shadows. The kit includes manual switches right on the hood, so if you need the light on for inspection or want to run the fan while grinding, you have total control at your fingertips.

The package comes with everything you need to get set up: the lamp housing with the sensor, the control box, all the wiring, and the switches. It’s a smart upgrade that protects your lungs and helps you see your work, letting you keep your gloves on and your focus where it belongs—on the puddle.
