Well it seems the problem is that I didn't put enough tension on the wire feed mechanism.

Then I killed power at the 1 bay garage I rent and can't find any breakers off in the house it's connected to...

It doesn't seem like I'm losing voltage so a bad connection doesn't seem like the problem.

I put a new .030 contact tip in and I'm running .030 wire. I'm not sure why the tip is recessed so far, that's how it was when I grabbed the welder from him.

I checked the connections and they seem fine. I doubt I overloaded the duty cycle, this was done in several hours over a few days. Not to mention I had to stop a lot to avoid blowing through the sheetmetal. The longest joint I did at once was maybe 2". It doesn't seem to work right doing flat s...

I already said it won't work properly in areas I already welded. There haven't been any speakers near the area or a rear mounted battery or anything. There will be a rear mount battery soon but not yet... The gas tank is now down to 500psi but this started when it was around 1000. It was 2000psi full.

Well it worked fine for 3/4 of the welding I had to do then suddenly stopped, so I don't think the type of gas is the problem when it already gave me satisfactory welds. I've both turned the wire speed up and down, I've tried every mix of settings I could. I briefly tried it in a flat position and i...

There's no wind, I'm doing this inside a garage with the door shut. I also didn't lose shielding, I even tried turning the gas up and it made no difference. I ran out of gas before and it acted way different. None of the variables (as far as I can tell anyways) have changed and suddenly I was no lon...

Here's photos before and after the problem and a photo of the welder tip. I tried welding downwards too and the same thing happens. A giant ball of molton metal forms on the tip of the gun. I tried turning wire feed down again and still no difference. I've tried everything I can think of, maybe some...

Thanks for the welcome. I've tried a variety of gun angles to no avail. Maybe I'll try moving the hose around but it didn't seem to be bent at an acute angle. I tried doing it in the same spot I already welded and it won't work right either. I stopped for a few minutes, went back to it, and all of a...

I've been reinforcing my car by welding 1/8" tubing into the floor pan with a Mac 110v MIG welder (using argon). I had no problem welding the part I was able to do from above then started on the bottom and got halfway through before it became impossible to weld. The welder tip started spewing o...
