In this video I show the machine that I made and our company uses for cleaning stainless steel after welding. A few things to note is that this will not work if the stainless is oxidized (Has a layer of black on top of it). The transformer is a 150va 120x12/24v step down, purchased from Automation Direct. The light bulb and socket are simply purchased from Home Depot and the wand was cut out of a piece of stainless tubing. a switch, also from Home Depot was purchased and a fan from amazon was laying around the shop to keep it all cool. The transformer winding was wired in series with the light bulb, allowing the light bulb to act as a current limiting device. This works because as the light bulb heats up the resistance increases, but the resistance at 120v is high enough to not permit more than 150 watts through.
