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) |

ok - versus trying to weld big gaps, I sliced up some sheet - to try some tacks.
firstly, HF clamps are not square a cause seem to widen as clamp is tightened. no quality control on the manufacture of these. so far it seems that HF mig cart and magnets and helmut are good buys. also, I see that I did not keep my 2 pieces of sheet perpendicular to each other and the few beads I made cause big warping. I have another 2 pieces set up, will try again. my hope is that 18 and 16 gage are a lot more forgiving than 20. Attached image(s) |
