Hey guys. I have a Millermatic 130XP and it has a problem that I hope someone here can diagnose for me. It occasionally welds well, and then sometimes will start to sputter. It does not have anything to do with overheating, because it will sometimes sputter off the bat after just being started. I have no idea what would make it weld great sometimes and then start sputtering other times, sometimes while working on the same piece of weld. I have changed the tip, but that didn't resolve the issue. Any advice? What should I be looking for?

1. Keep gun cable as straight as possible.
2. Make sure ground cable has good connection. Grind a spot shiny on whatever you are welding if necessary.
3. Make sure nut holding spool of wire is minimum tightness to keep spool from unwinding on its own.
4. Check tension on wire feed as described in manual. Barely tight enough to make wire coming out tip to push back against something.
5. If it's real hard to pull wire out of tip by hand, might need to remove wire and blow out liner.Miller Challenger 172

Hey guys im new here. Just wanted advice on welding some round tubing to 1/2" steel plate. The tubing is 1/2" wall thickness. Tubing is held in a horizontal position and cannot be moved which is why im having trouble with the weld puddle running and not being able to control it. What is the best pattern to use? Im using a Millermatic 252 with 0.35 solid wire and 75% Argon 25% Co2. This is a pic of how the first one turned out but i was hoping to make the second one look cleaner. My biggest problem is welding up under the bottom of the tubing the puddle is droopy and i cant control it.

Im having the most trouble welding up underneath the round tubing because my welds are drooping.
