Astro Power 130 Heat selector switch details

[32Tudor]

My heat selector switch began binding and didn't want to turn off. I took some pictures as I took it apart and found nothing wrong with it. I lubricated it as I reassembled it and it operates great. I saw the thread about a heat switch, looking for cam positions. It was back in 2016 and unfortunately did not answer my question. I find myself in a similar situation. I took pictures of my switch, but lost track of the position of the selector shaft, which made my cam position pictures questionable. There are three jumpers and I have them connecting #7 to center (unlabeled) to #2 and then #8 to center (unlabeled). If I could find a wiring diagram and get a few pictures of someone's working switch (on the outside), I could figure out if I have my cams in the right positions.

Hi
Here you have the same MIG, you can see the jumpers (one is missing) but it should be the same.

Thread 'Astro Power Powermig 130'

Feb 23, 2016

I have an Astro Powermig 130, made in Italy. My 5 position OFF + 4 power control switch got stuck while operating and I could not switch it back to Off. I took a couple pictures and then started to take the cam switch apart. Some of the pieces fell out, of course. Unfortunately, I took the cams out without taking pictures and am having trouble making sure they are in the correct position. I have contacted Bremas, as it is their switch but they don't have an exact match. I bought this at a yard sale so it has no data to support it and I can't find any information on-line. If anyone can help...
