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

Step 13 Regulated Power Supply

This old faithful ex R.A.A.F. unit will live beyond my years. So many features and made in Australia. This is the desired peak operating stats that reached 310 degrees centigrade. It took me under 15 seconds to reach this temperature from a cold start. Far better than waiting several minutes for a stock standard soldering iron to heat up. I note that at 16 volts, peak temp was at 270 odd degrees centigrade. At 18 volts, peak temp was 310 degrees centigrade. So I can figure out the maths as far as predicting temperature ranges exiting the nozzle at assorted voltages and amperage. The linear distance between theses ranges is of course determined by gauge of element wire, it's length and also the CFM of air flow through the nozzle.
