I have two thermadyne cutter of 51 and 151,if the fuse can interconvert using in working.
By fuse are you referring to a fuse inside of the unit itself? Or are you referring to something in the consumables that might be interchangeable between the two units?
If you could email me a picture or a more specific description of the problem I'd be happy to help.
