Tigging BY a Dummy 101
It all started when I had a big tig job coming up and I noticed I had only 600 psi left on my 336 cu ft (T) argon tank.
The job would need more than 600 psi so, being a cheapie, I thought of ways to use up the argon before swapping it out the next day.
Had some 1/8" alum sheet scraps and decided to tig up a pyramid.
Each side is 3" long.
Cleaned the alum with scotchbrite and acetoned the plates and 3/32" alum tig 5356 wire.90 amps advanced squarewave - 200 hz - 3/32" pointed 2% thoriated tungsten - 15 cu ft/hr argon.
Learning should be fun so here goes..........................
I have numbered the beads and added (comments my instructor would make.)
Please study them for faults - there will be a test and prize.
1 - First weld - ("ok at start but you forgot to back off on current as the alum got hot - you dummy - bead got wider and then look !!!!!!!!!")
2 - Second weld - ("I thought you learned from 1 but same thing happened - no burn thru but still too hot - wake up - dummy x 2 !!")
3 - Third weld - ("You took a break and let piece cool down enough to handle - ok looks a little better but don't get too smug.")
4 - Fourth weld ("Bead is better but now a little too cool hence the high bead. "You are really a dummy !")
5 - Fifth weld ("You let piece cool and ran another - keep trying and don't quit your day job")
OK - match the numbers to the letters and win a 2 week vacation - free airfare, hotel and meals - booze is on you.
First prize is Bikini Atoll.
Second prize is Tora Bora.
A - If you tig - every bead deserves your best effort.
If not, why the %&*%#@ are you here?.
B - Learn from (don't hide and show) your mistakes.
C - Get in a comfortable position before you tig -
you wouldn't sit on a cactus to watch the Super Bowl so why.......................?
D - Read the other member's posts and study the photos.
E - If you have questions - ask the forum members - the advice they offer is priceless and free.
A final question which started all this mess - "why don't you get a second cylinder"?
Duh - I have done just that.
PS - still have 100 psi argon left - guess I'll fill some balloons and roll them down the hill during tomorrow's soapbox derby race.
Lead balloons rock !

Interesting, what to do with it now.
Fix the bad spots, finish the welds down and make a nice smooth seamless paper weight.
If your into it or might save it for later,,, practice polishing it.
