Has anyone had an ESAB EMP 285ic that displays a critical error 003 on start up on the User Interface Screen and won’t do anything? Error 003 on start up locks the welder. This is a different 285ic welder and with a different problem. I have a pile of these bad welders.
I’m looking for advice on what to trouble shoot in the Main Power Board. Using the Service Manual, I went through all of the checks and everything points to the main power board. I haven’t found a cheep power board so I want to fix what I have.
Error 003 points to the DC Bus (400V) fault droop under load, PFC (Power Factor Corrector) not supplying 400V to inverter. But on start up, there is no load to droop and no heat for heat sensors to find.
I moved the Main Power Board to another 285ic welder and the error 003 problem moved with it.
Advice please on what to check or replace on the Main Power Board.
