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) |

per andyrew's request - here are some samples at different settings.
front and back of panel - thickness I am not certain of, could be 20 gage?? wire is 030 all done push style from bottom to top - but I barely see the molten puddle, I see the bright molten area as the sparks are flying but I don't linger there enough that I can say I am pushing a puddle at all. oh, and in between the top and bottom bead, I layed 2-3 tacks and for some reason, I keep reaching for the bottom knob - less today - for amps vs wire speed, I need to take my time and really look when I make setting changes.
