Screw on welding pen 737A

So I recently saw this welding pen in a youtube video


Which you screw onto these stationary welders. Do you guys think it will work with my welder? I have a Sunkko 787A

You screw it on where the normal welding pins are, like shown in the youtube video.

However his home breakers were tripping, which will not be for me as I have tried to putting the welder to 90, and it still did not trip the breaker.

I think it would work. You just have to make sure the connection between the terminals and the wire is solid.
