first post. i have 3 Esab 300 avs suitcase feeders and only one works. I found the good unit had a replaced kal 25 resistor off the lead that comes into unit. When i swapped new resistors into the broken units they blew out the resistor.
Electical repair shopped determined it was a bad main board in both faulty units. I have the boards at another shop getting looked at with a possible repair fix.
Anyone familar with these units? any help would be appreciated!!
