I recently read that an AC welder can be converted to a DC welder, and
all thats needed are either two or four very high amp diodes. The
welder puts out up to 240amps. I never measured the voltage, but I
think it's around 25 to 30. (I'll have to check). Two diodes will
make a half wave rectifier, but if my memory is right, I'll only get
half the voltage, whereas using 4 diodes as a bridge rect. I will get
the full voltage output.
Now, my question is this. How do I figure the amperage of the diodes
that I would need (for both methods), so I have at least 250amp
capacity. I'd guess 300 would be better to cope with heating. Of all
the years I puttered with electronics, I was never good at math. My
guess is that each diode should be 150A to achieve 300A. But I might
be wrong.
Can someone please help.
Also, where could I get something like this?
Thanks
