R tech told me the opposite today. They said lower the percentage the more cleaning. Will have to have another play tomoz night. Will look forward too seeing how good it can work though double boost to give me some hope the machine is capable once set right.
AC BalanceThis sets the % of electrode positive used during AC welding to provide a cleaning actionas alloys have a oxide layer that has a higher melting temperature than the base metal andthis needs to be lifted off.So you can control the amount of cleaning or penetration.Too much cleaning will cause the tungsten to wobble and split, Too little cleaning can resultin a dirty dull weld.So as you increase the % the more cleaning will happen however less penetration will beachieved.For most situations a setting of 30 - 40% will give you a good clean weld finish, If you goabove 50% you will find the tungsten will overheat and the end can fall of into weld pool.If you find you are getting tungsten wobble using 30-40% balance then you may need to goup a tungsten size.
