Electrical trouble shooting

[grey]

This is an old red AC 225 s.
What should transformer windings be? I need just general ohm number.


Where can I find such useful information on this type machine? (I searched the lincoln site but only found user manual.)

[grey]

this is a tapped transformer with "stepped control"
I just looked at the Hobart bools here and they are "infinite control"

Still, I need to learn about my red machine.

You might talk to a local repair facility, or contact Lincoln.

1. See if the Lincoln site has a downloadable owners manual.

2. It's probably very few ohms (<10) with a multimeter as most of the "resistance" is across the arc and the rest is "impedance", which is the magnetic fields trying to oppose the 60 cycle reversals of current.

that is helpful. I got 0 ohms on what I call the primary and secondary. There are two more coils that I did not check yet.

owners manual says, "take it to supply house and let them fix it."

I just bought the thing. Before plugging it in I want to check everything I can.

Thanks again for the education. If you know any more please mention it.
