Buy a new electric iron yellow 907, for the first time in the case of electricity, I put it on the iron frame, (iron frame for all metal) when I touched the iron cage bottom, appear obvious shock feeling, but the speed is very fast. The iron iron heating power line plug is double in addition, thin head iron clip, I wonder if this is a grounding, but when I got an electric shock from the iron grip is not grounded. I did not dare to go to trial ground state will get a shock.I would like to ask whether this is the soldering iron leakage, if you want to check, then how to check?
The plug of the soldering iron is two poles, and it is usually not leak, especially the new soldering iron produced by the Dachang, which is unlikely to leak. You can use a multimeter to measure the metal part of the two poles to the outside of the iron, and see what the resistance is. In addition, the thin wire head is an iron clip, which is used for grounding, because the soldering iron shall be grounded when soldering the integrated circuit so as to prevent the static electricity from damaging the integrated circuit. You'll never get an electric shock after grounding, but you'd better find out if there is any insulation problem, because if you don't do it professionally, you will rarely use this ground clamp.
Multimeter 10K file power line and shell, the resistance should be infinite
The iron plug is polar, usually is not leakage amount, especially the new iron production of large leakage is unlikely. You can use a multimeter to measure the poles of iron were the leakage of the metal part, see resistance value is how much, in general should be megohm. In addition the thin line the head is the iron clamp is used for grounding, because welding integrated circuit should be a soldering iron head part of the ground, to prevent electrostatic damage. Integrated circuit grounding must not be a shock, but you'd better find no insulation problem, because if not professional welding, rarely use this grounding clip.
