You going to fill the tank with water before welding on it, or purge it? Was it used before, be careful with it. Looks good. I have a small 4" metal circular saw, it makes short clean work of plate. I have used it on a few steel pieces but mostly aluminum. I would like a bigger one, may have to look into that Milwaukee. I haven't ever had a muliawkee tool that wasn't great, expensive but great.
