like i said welding .063 with my miller dynasty 200 working grate but now i need to weld a run that is over 6 foot long and cant get it to not warp please help
Reply:i have to TIG at least a dozen or so automotive steel panels every year....and they have to be PERFECT.....so here's what i'd try..after all your taks are done , try running anywhere from 2-6 inches , wait 9 seconds or the lowest u can on your Post-Flow , then IMEDIATELY air-quench 40-80 psi for 10-20 seconds , do over again and again.i know i could do it , just play with the #'s. hope this helps. thermal arc 252i - millermatic 350P - miller XMT, cp300ts, 30a 22a feeders, buttload of other millers, handfull of lincolns, couple of esabs - Hypertherm 1250 G3 |
