Heat selector switch question

[Mandingo]

Hi, I have a used Powermate Professional tote mig model 117-027 I bought off of craigslist a week ago. It works fine on the fill and 2 selection, but when I switch to 3 or 4 settings, nothing? Any suggestions?
Thanks in advance

You'll need to take a look inside.

You'll need to take a look inside.

actually, i've opened it up and checked the switch to see if it was dirty or damaged, and it appears to be ok, its in a sealed casing. Is there a fuse or something I should be looking for?

I TOO purchased a powermate tote-mig 117-027 from a guy off of craigslist and only the fill and the #2 heat settings (fill-2-3-4) work ! is this a defect? does anyone know how this could have happened and /or how to fix it? i couldnt find a fuse or anything visually wrong . please help!

What is a Powermate Professional tote mig? I see there must be more than one but cant say I ever seen one.
