Every time tip makes contact, there was "click" inside.
The clicks you hear (and feel) are from the magnetic switch mechanism in the shaft moving back and forth due to being drawn to, and released from, the slug in the tip as the slug becomes magnetic and non-magnetic when it goes below and above (respectively) the rated temperature. This switch controls power to the heating element in the shaft that heats the tip. You have some types that I don't, so as I said, if nobody else wants them, I'll gladly pay the postage to mail them to me. -- Scott
