New rotary wheel
I've been on vacation for a week and am back to work now.
Mark suggested that if I'm not going to increase the size of my rotary gap
wheel that I should only go up to 12 electrodes. Since I almost had it
finished I thought I would go ahead and try it with the 16 electrode
configuration as planned.
I tried it at lower power first, with the welder set at its lowest setting.
Best performance was obtained with the speed up about the same rate that I
used to run the rotary with 8 electrodes. Then I cranked the welder up to
full power and fired the coil again. We now have major thick blue bolts that
hit everything in sight - and frequently. I was very surprised to look down
at the meter and see the primary pig current way up - swinging back and forth
between 35 and 45 amps!! The highest I could get before was 23 amps.
This thing is producing major power. I can't tell how long the discharges
are because my basement is too small. It is kind of scary to sit at the
controls about 12 feet from the coil and not flinch when the discharges start
coming my way. They mostly want to hit the floor joists, heat ducts, water
pipes and the wire strike shields that I have all over the ceiling.
Setting this thing up in the garage (outside) is going to be a lot of work
but I guess it's time to get started.
