Here we go again on this plasma cutting machine
First the chopper boards when on this machine now the plasma power supply controller boards
( Bad IGBT module when bad and what else I do not know at this point in time—> bought new chopper units I will try to repair them later when I have some time)
This machine is about 10 years old and all kinds of problems are coming out this unit granted the machine gets a lot of use
The IGTB module went bad also a 10k ohm resistor is open no reading at all
It has two capacitors that 3MFD that with my Blue ESR meter shows 0.00 ohms ( with them removed from the board )
With my Radio Shack meter shows 3uf —> so my question are these two capacitors bad
Below are some pictures of the board the two capacitors in question
I am also going to list the parts from Digi-Key that I think they are if I do not have the right parts please let me know thanks
Here is the resistor

Here are the capacitors

Transient Voltage Suppression Diodes —> is there a way to check this type diode

It also has one of these also

I am also going to recap the board
The one thing nice about the manual for this plasma unit it gives you resistance checks to find out if this board is giving you problems or not
