Interesting... i fail to see why you need two different steps to regulate the
current of a pole pig. Say i get these oven elements do as you say: put a
them in parallel with a tap switch on each of them. then i will put this
arrangement in series with the leads of the arc welder. this whole
will be hooked in series with the primary of the pig. ok.... If the resistive
ballasts regulate the current in steps then what or why do i need an arc
hooked in series with it. What happens if i turn the dial of the arc welder
the ballasts in place set to 22 ohms? What happens if i just take the arc
out of the circuit?
