Hi, I need a little help on just some of the very basics of hooking up a mig weling machine. You see I just got back from a temp service and all they had open was "mig welders" , so I told a little fib. I've seen it done and have been around it, I've even done a little pipe welding on the tig rig. I just can't rember how to hook up the cables and what not, because I know the - and + are opposite (I think). But anyways If yall could just help me out and just run through the basics for me that would be awesome. My interview is soon. thanks. I just got the call I have to be there in 10 minets please some help!!!
