post a picture and model...

the way i see it, in the worst case it is open loop regulated iron using simple triac circuit. that is the only type of regulator that does use mains frequency for firing angle. and if so, the scale on temperature adjustment will be compressed slightly but i do not see how this could damage anything.

btw. your soldering iron is safe but the question is worded in a way that does not exclude risk of damage.

for example if change of destruction was 99% then "can i use it without damage" would still be yes... it is possible....even if possibility of success is just 1%. just saying...

Consider that a soldering iron is a RESISTIVE LOAD, and thus the impedance does not depend on the supply frequency. So it will work the same, 50 Hz or 60 Hz.
The safety rule is the same: "Only grasp by the handle end!!"

Welcome to AAC.

Damage can occur if the heat dwell time is excessive. You can overheat a component or even damage a PCB. Even a low temp iron can cause damage if not handled properly.

If you look at data sheets some will tell you what temperature to solder them at AND how long you can dwell with the heat. Exceeding that time can cause damage. You can touch the tip of a soldering iron for an instant and not sustain any damage. But if you keep your finger there too long you'll blister and burn your flesh.

I DID learn that trick a bunch of years ago, clearing the tip of the soldering pen with my thumb. And to NEVER clear it between thumb and first finger.!!
