Maybe I missed it somewhere but am not having much luck getting burn back settings correct. Can someone please give general advise on where to start? Also, getting a small ball on the end of the MIG wire. .035" Lincoln, welding 1/4" diameter cold roll bar, 21 volts and 450 IPM as suggested by Kevin Caron as a starting point. Thanks for your help to an old (72) noobie.
