I have a harbor freight special and the 1st 2 spools a ran thru it were utter crap welds for the most part. Very hard to judge speed for me. Yesterday I picked up a spool of Radnor while from airgas and all I can say is WOW.
Welds are laying out flatter and smoother. Once you remove the flux with a brush the welds are so clean and shinny I hate to mess with them. Not bad for a 14 dollar 2 pound spool.
