DIY Hot Air Soldering Iron using 12-18volts DC at 2-3 amps

Step 2 The fan

Part of the fan assembly from the paint stripper blowers. 17VDC fan shown here. I removed the bridge rectifier and capacitor and used this type of fan, as it was all I had to deliver air into the soldering iron. This proved to be a lucky situation later, as I had the right amount of air flow passing through and in direct contact with the heating element.
