Repair method of electric soldering iron
1. The maintenance method that the soldering iron does not heat up after being powered on
(1) It is discovered that the soldering iron head is not hot when it is powered on. Typically, either the soldering iron's core wire or the power cable have broken. If it stays still, an open circuit fault has occurred.
(2) Before measuring the two leads of the soldering iron core, see if the lead wire of the plug itself exhibits an open circuit phenomenon. If not, remove the bakelite handle. If the multimeter's pointer still does not move, the soldering iron's core is damaged, and a new soldering iron should be purchased.
(3) The 35W internally heated soldering iron core has a resistance of 1 between its two leads. If the measured resistance value for Skfl is normal, the soldering iron's core is in good condition, the fault lies in the power lead or the plug, and the majority of faults are lead wire open circuits. A new soldering iron core of the same specification must be inserted into the connecting rod to replace the old one. The lead wire must then be secured to the fixing screw, and the terminal must be tightened. brief a circuit.
2. The maintenance method of live iron head
(1) The soldering iron tip's electrified fault is caused by two things: first, the power line's incorrect connection to the grounding line terminal; second, when the power line detaches from the soldering iron core's terminal and comes into contact with the grounding line's screw once more. The soldering iron's tip is consequently charged.
(2) Components may be harmed and electric shock incidents are easily caused by this form of failure. Checking the crimping screws on the handle of the electric soldering iron frequently is required to avoid the power wire from coming unattached. timely preparation.
