Greetings All,
I'm just curious, How does the electronics on my Miller 180SD Tig machine Actually control the amperage?
In my 'good old days' I took apart an old A/C Stick Buzz Box. Its internals were fairly simple. When you cranked the Amperage range selection handle, it appeared to mechanically move parts of the large transformer. Thus I assumed the old buzz box was nothing more than a huge variable transformer.
I guess my question is, since I know the Miller 180 is a transformer based machine, how exactly are they controlling the transformer output?
I've built a 2KW "TOY" Induction heater, so I'm pretty familiar with general analog / digital electronics,
Thanks.
Take Care, James Lerch
