What are the maintenance methods of electric soldering iron
1. The maintenance method that the soldering iron does not heat up after being powered on
(1) When the soldering iron is energized, the tip of the soldering iron is not hot. Generally, the power cord is disconnected or the core wire of the soldering iron is broken. In this case, use the R×lkn block of the multimeter to measure both ends of the power plug. If it does not move, it means that there is an open circuit fault.
(2) First check whether the lead wire of the plug itself is open circuit phenomenon, if not, you can remove the bakelite handle, and then use a multimeter to measure the two lead wires of the soldering iron core, if the pointer of the multimeter still does not move, it means that the soldering iron core is damaged, and the soldering iron should be replaced Heart.
(3) The resistance between the two leads of the 35W internal heating soldering iron core is 1. Around Skfl, if the measured resistance value is normal, it means that the soldering iron core is good, and the fault occurs in the power lead and the plug itself, and most of the faults are lead wire open circuit. It is necessary to replace the soldering iron core, insert a new soldering iron core of the same specification into the connecting rod, fix the lead wire on the fixing screw, and tighten the terminal. short circuit.
2. The maintenance method of live iron head
(1) The reason for the electrified fault of the soldering iron tip is that, in addition to the wrong connection of the power line to the grounding line terminal, there is another reason, that is, when the power line falls off from the terminal of the soldering iron core, it touches the screw of the grounding line again. As a result, the tip of the soldering iron is charged.
(2) This kind of failure may easily cause electric shock accidents and damage components. In order to prevent the power cord from falling off, it is necessary to regularly check whether the crimping screws on the handle of the electric soldering iron are loose or missing. Prepared in time.
