When on the stand the mains fed to the iron is half wave only for economiser
mode (1/2 power), the iron rest on a suitably mounted stand micro switch that
is connected to one of the bridge diodes. When the iron is picked up, full wave
is restored for (normal power).
An added non locking press button switch mounted in the iron handle, this
boosts the power by connecting a 350V 10uF with a 22R in series (47uF/10R for
60W) housed in the stand (iron not earthed 3 core cable! Or use 4 core rubber
flex with an earth) resulting in approx 300V peak DC from the mains being used
for high power. This is approx 2x the normal power, hence the non locking press
switch!
Make sure all mains connections & switches are safe (properly shrouded heat-
shrink) to avoid shocks etc.
A neon (with series 220k) across iron can be used to indicate the power status.
