    I have a miller gas powered welder that quit welding. Removed the cover and it has a circuit board that has a bad diode on it. I got new diodes but there is one capacitor on the board that I cannot find new, the manual says it is ceramic 0.01 uf 500 volt dc, the capacitor has zu5, .01m, 500 v printed on it. can anyone tell me the correct capacitor to use?

    Any ceramic 0.01 μF capacitor with a rating of 500V DC or more will suffice. They are common as muck and cheap as chips.

    You may get away with some other type depending on the circuit. Best to avoid polarised (electrolytic) unless specifically specified.

    FWIW, "Z5U" designates how the cap responds to temperature, in this case +22%, - 56% in the range -10 to 85°C
