Lincoln Weld Alert remote. 100 foot cable and four 110v power outlets. The remote box has good magnets on it, and the cable has the quick disconnects to store the remote box safely. These are both 14 pin connections to the machine, so they are compatible with Lincoln 305G, and the Vantage lineup. Also with a lot of Miller units like the 325 or the 302. These are not compatible with welders such as the Classic line or anything with the 6 pin plug.
