View Full Version : Hobart GF-250 Exciter Rectifier Help Needed

04-17-2013, 10:24 PM
The exciter rectifier on my Hobart GF-250 is shot. The rectifier consists of 4 diodes. I need to know the specs on the diodes so that I can buy replacement diodes. Anyone know? Tried to upload a picture but got an error.

Hobart part number is 430390 for this part.

A 25 amp bridge rectifier will work fine. They have all 4 diodes encapsulated in an epoxy blob.
