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) |

Jim, easygrind is about 4x's what regular wire is and you won't need that until you start your exposed body work. FWIW, I do most all my welding in the garage where the wind doesn't blow and 10psi of mix is usually enough. If there is a breeze coming thru I'll boost it up to about 15psi. The copper spoon is the trick and you will burn thru a few (thinking you've managed to weld copper to steel (IMG:style_emoticons/default/av-943.gif) ) in the beginning. I don't know how our resident body experts keep a spoon in place but I use cheap magnets when my one and only pair of large C clamp pliers won't fit. One more beginner tip; clear the area of flammable materials. In the past 9 mo's I have ignited 3 shop towels right next to my head when welding. (IMG:style_emoticons/default/slap.gif) PS, get some .023". You'll need some and a small spool is only about $7.
