smps schematic drawn for welding, now testing.

Hi there


I have change a constant current inverter for welding in a constant voltage version and
I can als use constant current if i am right here, I have use a part of a normal supply
and recalculate the way things are do right with welding, output elco,s need there
for use as constant voltage, I have not used insolated feedback, I can do with a opto
coupler but I do not now what happens then, because welding is something else then
a ordinairy smps supply.

I can remove with a relais the output capacitors and disconnect voltage feedback
getting a mma welder with high openloop voltage.

thanks for the advise if you see some what can be changed for the better.


regards
