Old style rectifiers.
I have an old 300 amp Arco arc and TIG welder. It does a fine job stick welding; however, the high frequency section is not working. I downloaded a manual that has a small troubleshooting section. First thing it says is to test the diodes and rectifiers. I need some help on how exactly I test the rectifiers. They are the old metal style. Which terminals are the anode and cathode? The welder has 2 small and 2 large rectifiers as shown in the pictures attached.
Thanks for your time
