Millermatic 180 Diode replacement

[cruizer]

"An RV1" sounds more like an isolator never the less does not comeup in either of the 180 models.

Do you not notice that we techs really like the serial#. It contains lots of needed information as sometimes, people think the machine is one thing, but really its something quite different.

Can anyone tell me what diode should be in the RV1 location of a Millermatic 180. Mine has burned up and I can't read it to tell what I need to replace it with.
