At one my work stations where I put together small prototypes
I finally discovered why the desoldering vacuums wand needs to
be set higher in temp. I just wrote it off as a defective sensing
circuit in the station because I tried another wand on it. However,
the other day, I found out what was causing the defected reading and
throwing off the controller..
R.F. around it causes the thermo coupling circuit to register higher
readings and forces the controller to throttle back. My guess is it may
have something to do with the ring near the tip that handles the seebeck
circuit.
The R.F. source is a repeater in the 440Mhz range near by, just over
my head. Lately, it has been very active in our locality.
I will need to investigate more, the type of input it is using.
Something tells me it could be monolithic in nature and the front
end maybe rectifying the signal?
