   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.
