Metal Dust/ filings will KILL any electronic!!!
My dad owns a metal Polishing Shop, and has burned through computers/ printers/ phones/ routers/ speakers/ etc. at an amazing rate. They're all magnets for the dust.
Aside from the electronics, a lot of the machinery he uses has to be cleaned out daily, as the metal dust gets into the motors and clutches, and soon enough, he'll have a dead machine.
I hate it when our salesman just put machines in place all "willy nilly", without first researching what kind of stress the machine will undergo. Especially fab shops, and welding shops!
If there is as much metal dust as you say, I would suspect it has worked it's way into the magnetic clutches, and it's going to be an ongoing problem for you. No easy fix here.
