when i set my amps for my open root and hot pass with 6010/7010( may not be orthodox)
on a scrap piece strike an ark and bury rod
.
keep turning up amps until arc does not snuff but will walk across piece if you are running downhill leave it there... if running up, turn down 5 amps +/-
this does me good for a place to start i step in my hot pass with the crown knocked down and watch the wagon tracks between the puddle and end of rod
try it
also needs to be added that i run wider gap up than down if 1/8 rod i use a 3/32 gap and 1/8 gap running with up 6010 and a little closer with 7010 if it help cool
an old pipe liner taught me this and i swear by it
