Heres the deal. I can't find any info, like the catalog has. Found one on craigs list @ a descent price. Its a voltage sensing unit. Does this mean it'll work with any stick welder? How does it hook up? I have a 22a i use in the shop, but i'd like to have a wire feeder to run off my tralblazer 302on my service truck. I know it will run .068 wire, which i use alot of. Does this feeder have a gas valve? Seems like it should. Thanx in advance!!
