Hi,

I recently got a soldering Iron in view if soldering SMD devices. Its fine as a needle. However, I think there is a problem.

Its a 12V, 7.5 W Ac/Dc soldering iron. Came with no power supply. I'm using a 12V 1.5 Amp power source. when i touched the tip accidentally i got very mild shock. i measured the voltage between power supply ground and soldering tip. It measures ~10 V . Does it mean the soldering iron is bad? if i try to solder an IC with this, will that voltage destroy the IC ?

Please let me know.

It should be fine as the PSU ground should not be referenced to the circuit you are soldering.

I dout you really got a shock, you can only just about feel a tingle at 60V, prob just sharp tip or too hot.

hi,

i also got a very mild shock when i touched the soldering iron. i was tinning the tip. Soldering iron gave the mild shock when the tip was in contact. Now how can i explain that :!:

Well if you really did get a shock then check the volts between the PSU + and - and a earth, maybe your power supply is faulty.
But the soldering iron should be fine, 12V wont give you a shock.

when checking the PSU to earth remember to try both AC and DC
