lowering temperature of a hot glue gun

    I'd like to lower the temperature of a cheap $5 hot glue gun in order to
    use bees wax.

    Would a simple dimmer used for lighting work?

    Yep, a triac type dimmer for incandescent lamps should work fine to control
    a resistive load like a hot glue gun. Of course the power rating of the glue
    gun cannot exceed the power rating of the dimmer.

    Re:
    The glue gun is typically just a resistive heating element device; so
    yes, a light dimmer should work well as a power/temperature control.

    I took several apart - there is a bimetallic switch inside with an
    adjustment screw to set the temperature. Even the cheap tiny guns
    have them.

    You could use a dimmer to do it, but that would negate the advantage
    provided by the thermostat - quick warm-up and fast recovery. The
    faster you use the adhesive the more current the gun uses to replenish
    the lost heat. Add a dimmer and you become the thermostat.

    It is probably a matter of time before they start using PTC wire to
    make the elements to lower the cost - just in case you tear into one
    and don't find a thermostat. If they can do it to make heat tape to
    keep pipes from freezing a glue gun should be next.

    I bought and disassembled several a few years ago with the idea of
    coating magnet wire with adhesive by feeding both wire and adhesive
    through the nozzle - all had a thermostat from the $29.95 gun to the
    $4.95 gun.
