my original argon valve was bent up and leaked, so I ordered a new one. it had again, different sized threads, jeez.
so I went to ace ( r towel advice) and went with barbed fitting at both ends since the new argon valve came with a 1/4 barb already. question - when you are done welding and want to purge the lines of argon, after shutting the valve on the tank, do you have to waste wire or is there a way to purge without wasting wire? also, I expected the bead to stay at 15 psi when i turned the brass valve open, but it only rises to 15 psi or what ever I set it at, when I pull the red trigger on the mig - is this normal? also - I prepped some of my old real estate signs for practice : ) jim Attached image(s) |

You are starting off by trying to do one of the hardest tasks (bridging a 1/16" gap). I think your learning curve will end up faster if you start with just a bead.
I suggest: 1) Run a straight bead 4-6" across your practice piece. Try push and pull, flat, uphill and downhill. When you can make a nice bead, move on. 2) Lap joint - cut a piece off your practice piece and scab it over part of the remainder. You can also drill some holes in the cut off piece and practice plug welds. 3) Butt joint - get two piece with nice, tight fit-up. 4) When you get comfortable with the above, work on filling a gap. Hope this helps. P.S. I would grind more (probably all) paint off your workpiece. |
