This is a little update on my TIG welder conversion. I am trying to
convert it to a multiprocess welder, CC stick, CC TIG, CV MIG, and
also plasma.
I have a PCTI SCR firing controller, and bought a Cubloc
microprocessor to control it. Readers of SED may have a little more
details, which I am not sure how deeply I should get into (maybe no
one is interested).
As of right now, after writing about 1000 lines in BASIC, and wiring
the microcontroller and relays into the welder, the following is
actually working:
1) Stick welding
2) TIG welding (gas, water, high frequency arc stabilization on
demand)
3) Arbitrary power supply mode where I can just dial in voltage and
current
I am quite happy in that the power supply can let me do all the things
that I could do before.
I already have BASIC code for pulsed TIG, but I have not yet tried
it. Just recalled that I had it, but it is ifdef'ed out for now.
Of interest is the fact that high frequency does not seem to damage
anything, even though the welder is open.
I hope to soon receive a Digimig wire feeder by L-tec/Linde. Perhaps I
could actually get it to work (it is kind of complicated, as I
learned). I have some MIG code, but likely it would need to be fully
replaced.
Also I do not have the foot pedal working yet.
