first tig aluminum practice

admin

well i finally got to get some time with the sycro250 i got awhile back time to start the journey. i have practiced some and have got to where i can keep the tungsten out of the puddle most of the time and am getting better at dipping filler. my biggest problem is moveing steadily and pedal control working on travel speed to try and have a uniform size instead of an ever wideing bead heres my first attempt really since i got this machine several months back couple beads were 3/32 pure and couple were 3/32 lanth ..090 5052 al  4043 filler sorry my cammera skills arent the best         350P 30A spool gun cut master 51  syncro 250 other stuff " take a dog off the street and make him prosper and he will not bite you sad the same cannot be said for man" i didnt use punctuation just to piss you off
Reply:They look good. You need a bit more heat control, but I've seen a lot of aftermarket parts out there with worse beads. The only 'bad' habit I see is not doing a double-dip at the end to prevent cratering. If you start doing that at the end of every bead, even practice, it becomes second nature. Is your synchro capable of balance adjustment? If so, run less cleaning (higher balance # on miller welders). IIRC, on clean aluminum, you want your etched zone around the bead to be about 1/8" wider than the weld bead. I'd practice on thicker aluminum to start off with, it's more forgiving, and gives you more time to adjust heat input before falling out on you. But not a bad start, not by any means.Miller: 200dx, Bobcat 225, Passport, Powermax 45, Milwaukee: Dry Saw, MagDrill, grinders
