I don't have a proper garage or welding space so i do most of my welding outside and cart my welder in and out as i need it. I recently chopped the posts off this old potting bench to make it a welding table. I am planing on covering it with a 306L stainless sheet. My question is what is the minimum gauge stainless i should use to cover the wood. I am assuming that gauges of sheet metal carrying current is not too much different from gauges of wire carrying current. I.E. you want to make sure its big enough to carry the current at hand?? The largest welder I will be using is a Lincoln Ideal arc Dc 250. Since the wood will be carrying most of the weight I am not really worried about thickness for structural support and i want to go as thin as possible to keep costs down.
Any help and suggestions are appreciated.
