why is this so cheap? I'd like to be able to do aluminum and this is about as much as I want to pay. It looks like I'll have to do some rigging to get my welder to hook up to it http://www.mig-welding.co.uk/forum/showthread.php?t=8472

Does it have accomodations to turn the gas valve on and off? Variable speed? It is hard to say, I can not find a good write up of it's features???
