Airco msm250 ac/dc

Hello fellas, just picked up this old airco machine. Thought it would be a good one for people who stop by to use. Anyhow I never used this style of pins that connect to the machine,seems like they must have a slight taper or at least the sockets might. But they don’t go the whole way in I want to say you might be able to see a 1/4” of the pin when it’s tight is this normal? Anyway it’s been fun cleaning it up and going over it. I can’t get over how heavy it is for such a small box it has to weigh a couple hundred pounds. Thanks for any insight

yes that is normal the plug and the recp. are tapered.

Ok so about 3/8” of the stud will not go in? I was thinking it would almost go up to the insulation on the handle. So this is perfectly normal?

It allows for the pin and/or socket to wear some and still go in until tight.
