   I forgot to mention   
      
   * almost no slag - just a bit of glassy substance - so no slag choking   
     the weld area (the "fast freeze" is a corollary of this - no slag?)   
     as you tack-weld   
      
   Running 6010 open-arc isn't impossibly hard on the welding machine.   
   The voltage when running is higher than with other rods.  Why would be a   
   problem for a really feeble inverter - 20 years ago some low-end ones   
   would only run 6013.   
   If run it much like a 6013, with a bit of arc length, is "just" "nice".   
   Never thought to do that with first learning keyholing.
