Auto reset thermal fuse and standard fuse combo is a proven winner Some high horse trotting soldering station manufacturers and their corpotrolls may wanna take notes here but suggest strongly to rig up a SAFE, cheap (!) and easy way to pre-test the thermal fuse/s before install,
taking into account the ambient enclosure temperatures to be expected under most operating conditions
i.e. installing the wrong temp value that heats up and cuts out at random on a hot day will create more work for you to troubleshoot and fix,
with no fan to keep you cool
and pre testing can help verify you haven't installed a dud from a bad OHL production batch,
which lets you down, just when you really need it to work and cut out!
