I went and spent another $20 on surface pre- and post- prep discs this weekend. The welds are strong, and when ground down flush you can't even see a seam. I did a little destructive testing and the metal broke before the weld, so I know it's working. It just looks like the wrong end of an ugly dog.


Your experience with that little machine last year may well be a clue to this, as that is what my stuff is moving more and more towards. There was a good chunk of time that I didn't use my welder and the wire sat up. Maybe it does just get old...

dubby,

Photo mentioned about welding outside. If you are not welding outside is there some sort of fan or exhaust system running now that has not been on or running in the past when all was good??

Not that I'm really aware of. I do get a pretty good cross breeze on occasion through the doors, which is the only way to survive the summers here, but I'm pretty mindful of them when I pull the trigger.


Really, it seemed to do better outside when I was welding on the boat trailer hitch than it has inside.

Close all doors and stop all air movement. That will eliminate some factors in this, and that might even be the problem.
I am 98% certain you have a gas flow problem. The other thing could be some bad wire. Did you change wire and start having this problem.
Also check to see it you have a small hole in you hose that goes from the regulator to the back of the machine. If you do, then it will suck in air into the line and youll have problems.

I was talking to a salesman from the welding supply shop that supplies where I work.. I had the same issue off and on.... He said is sounded like the metal (chain links for snow chains, new product) may have been contaminated with some kind of oil... such as from heat treating
