I have a soldering station that has a strange problem.
When I press the button on the solder sucker it works just fine and vacuums up the solder but when I release the button there is a huge surge of current that blows the AC power input fuse. a 3 amp fuse.
The station works just fine except for this one issue.
The transformer is wired directly from the AC power and then it powers the rest of the system. The motor is wired to the output of the transformer and is controlled by a SCR. I have replaced all of the parts in the motor circuit on this board and I still get the problem.
Can I just put a Diode or resistor and a cap across the motor leads and have it suppress this kickback?
I figured I would ask before I did more damage.
Thanks,
Russ
