Anodizing pitting problem

+++

The problem is material anodizing is pitting. Not all the time mind you. It has been stated that when both the welder (high frequency) and the rectifier are in use the problem occurs. But not all the time. Does this have to do with shielding or lack of. The solution. Or something else.

I don't think enough info has been provided for anybody to do anything but take a wild guess. But if the problem happens while welding, and not at any other time, it certainly does sound like the electronic noise of the welder may be upsetting the SCRs on the rectifier.
