I am for sure no electrical/electronic genius, but I think the only way that works is if the bulb and the iron have the same wattage rating (which equals the same resistance). Double the resistance for half the current flow...If you series a 120v incandescent bulb with the iron it will cut the heat in half - 60 volt drop on each device.
You might need a true RMS meter to accurately read the output voltage from the dimmer..
When I searched how to measure voltage I found a lot of videos all showing the same approach.
The attached image shows what I found, is this the correct way to measure for out going voltage
or do I need a different way to measure ampereage in order to reduce a 30 watt soldering iron to 15 amp's?.
