Hey guys, I just bought a brand new Millermatic 211 from Weldfabulous as my first ever welder.

I haven't really been having much luck with it. I've tried using it on three separate occasions. The first time was pretty rough.

The second time I tried it out, a couple days ago, it went pretty well. I made a few okay-for-a-noob horizontal and flat joints like this one: http://i.imgur.com/iNtD8Ih.jpg

Today though it went pretty horribly again. I used all the same settings as when I laid beads like the above photo, and the gun was stubbing like crazy. I tried checking all the connections, gas flow, putting on a new contact tip, changing ground clamp locations, and anything else I could think of or what the guys on Welding Web could suggest. I simply could not get the machine to work right. Using niether Auto-Set or the door chart settings could get it to work right. I tried using both the 220V generator and 120V wall socket. Eventually I was able to almost cure the stubbing by pretty much halving the WFS but it's too cold because the bead now has a tendency to pile up instead of tie in. I basically went from making welds like the above photo to this: http://i.imgur.com/lag5bBD.jpg

I'm really reluctant to say so, but I think the welder might be defective. I REALLY don't want to go through the trouble of shipping this beast back to Weldfabulous if that's indeed what the problem is, maybe Miller would let me take it into a local authorized service center?

Here's a video I took of what's happening: http://www.youtube.com/watch?v=POBYWelr-AQ
