I think that is in part because 6010 doesn't run on all the machines 
that could fly through 6013 and 7018.  Only in recent years have I see 
mif price import machines able to run 60610 reliably, and some of them 
have shown mixed results from one machine to the next of the same model. 
  I can't speak to older transformer machines.  My Lincoln cracker box 
barely ran 7018 well.  My only other transformer machine is the Miller 
MIG box.  WEll I do have an ancient Hobart (Real Hobart, not Miller 
Hobart) generator welder, but my dad parked it decades ago when it 
melted its starting battery.  I haven't got around to trouble shooting it.

Thanks for the info.  While the odds are never zero I am unlikely to run 
6010 any time soon.  There is always that chance.  I will have some 
questions about mid thickness overhead welding soon.

Same to you.
