Hi rivet head
I have sodick A320 and it is eroding away gradually my expensive hirschmann tooling the reason for this i have been told is due to secondary sparking from charged particals in the tank. Possible cures are:
1 Keep filters regularly changed
2 Older machines tended not to have EF11 or equiv Reverse polarity
3 lumps of zinc in the tank which tend to get attacked first.
Out of interest what machine is the fixturing for ??
What kind of fixturing do you make?? Might be interested ??
