Hello sorry if this is the wrong place, i'm pretty new here. recently i got a 30w solder iron and found this instructable to make it adjustable https://www.instructables.com/id/How-to-Create-an-Adjustable-Soldering-Iron/ I know it won't be as good as buying a real adjustable iron but this is cheaper and will work. I have a little potentiometer that i got from a lamp but unlike most it only has 2 terminals and a space for a third. i did some experimenting and it seems to work fine, the 2 terminals are a middle and one to the right then a space to the left i hooked a wire in the space and it basically worked in reverse to when it clicked off it turned the (in this case) motor. so my real question is how do i wire this up, can i just wire the "hot" wire threw the pot and will it work to make my iron semi adjustable the only info i have on the pot is that on the top it says B500k i can take a picture of it if needed.
