My advice is just like an air compressor be sure to go "Over Kill" with whatever you by. It's better to have a compressor & welder that is too big for any job you may have t hen it is to have to wait for the compressor or welder to catch up to what you are doing..
THIS is what I have, it's truly over kill for anything I will do or have done but for the $350 I paid for it back in 93 I'm still smiling ear to ear every time I use it....joe
