Welding wire ?

Dave is right!

I had a Harbor Freight welder a few years back. Not sure if that is the same one or not but it looks similar. It was a POS I wound up stripper the feeder wheel inside within the first week I had it after that was fixed. I was welding the exhaust pipe on my father's work van when it overheated after about 20 seconds or so of continuous use. Felt like forever just to get it welded together. Finally got fed up with it and got a new welder a couple years ago. I picked up a Lincoln 3200HD and it's perfect. Handles everything I ever used it for without battin an eye.

BTW I also couldn't find the adapter to hook it up for gas either. If remember right the gas tubing was a diameter that no one carried. I think it was only a 1/4' wide or something like that.
