I try to find welding transformer design-calculation but so far no luck. Any help is welcome. I send for standard EI transformer calculation up to 1KW.
Old-school welders use a variable-core scheme where
the "iron" is moved into the solenoid to set an output
current level. Similar to a mag-amp. I expect any science
behind this, is pretty old and not common in research
papers.
New welders are just big DC-DC converters with peculiar
control scheme(s).
Thank for good tips. So far I search practical transformer calculation in short circuit mode. I think this is used for making transformer for welding. Correct me if I am wrong.
Any advice or idea is welcome.
