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) |

.023 for 24 gauge
.030 for 12 gauge (1/8") YMMV, depending on your experience level Trying to bridge a gap with the wrong size wire right out of the gate will only frustrate the hell out of you. To do sheet metal right with minimal warpage, you need to weld a series of SHORT 1/4" length beads every 6 inches, then go back and do the same every 3 inches, then every 1-1/2 inches, etc. until the butt weld is complete. Keep the .030 in and get some 1/8" raw steel plate and practice running beads as speed metal army stated above. YEARS AGO, as a young welder just starting out, I didn't have access to a MIG. SO I got real good at welding sheet metal with a stick welder. How'd I do it? LOTS of practice. (IMG:style_emoticons/default/welder.gif) |
