- For All,
I have obtained all the parts needed to make a
cheap stick weldernator. However, my 2 HP motor
turns CCW and the alternator is to turn CW.
Any thoughts an how to connect them?
How do I reverse the motor's direction of spin?
It's been suggested to use a chain and sprocket
or worm drive rather than belts to drive the alternator
to reduce slippage loss. Any thoughts on how to do this?
Also, I fixed my MIG and the pipe Cole-ish drill press is
welded and almost complete. Pics and tests to come.

A 6 millihenry choke is an inductor (figure wire would around a steel
core) which makes the arc much more stable. When the current starts to
drop, the inductor puts more voltage across the arc to keep it going.

not constant current or constant voltage.
