motor control using welder parts

Post by RACEPUMPER »

Has anyone controlled vac motors with the amp switching gear from a welder? I have a 180 amp mig welder that I can use parts from.
Any thoughts?

Sell the welder and buy some parts from Bruce.
There is no other way of using any of it.
Also known as the infamous "Warpspeed" on some other Forums.

Is a good Idea,but the welder have a steps control,and you can have the problem to cannot find the perfectly depression,because it stay between 2 steps....A infinite position control(potentiometer) are obligatory.
But a system can be to used is the same of very old stick welder:a wheel with a long screw control the air gap of electrical internal "transformer"(sorry I don't know the right word).
