Soldering iron maintenance methods
1, the soldering iron is not hot after power maintenance method
(1) when the soldering iron is energized, found that the soldering iron head is not hot, generally is the power cord off, or the heart of the branding iron line broken, encountered such a situation, the multimeter can be used to measure the two ends of the power supply plug R × lkn block, if the multimeter pointer does not move, that is, the fault of the broken circuit.
(2) first check the plug itself whether the lead is disconnected, if not, then you can remove the gum wood handle, and then use the multimeter to measure the two leads of the iron heart, if the multimeter pointer is still not moving, indicating that the iron heart is damaged, you should replace the iron heart.
(3) 35W endothermic soldering iron heart between the two leads of the resistance value of 1. Skfl or so, if the measured resistance value is normal, it means that the iron heart is good, the failure occurs in the power supply lead, and the plug itself, most of the fault is the lead break. Need to replace the iron heart, will be new with the specifications of the iron heart inserted into the connecting rod, the lead is fixed in the fixing screws, and tighten the terminals, at the same time, to note that the iron heart to the iron lead to cut off the excess, in order to prevent the two leads short-circuit.
2, the iron head charged maintenance method
(1) The reason for the soldering iron head charged fault, in addition to the power cord is wrongly connected to the grounding wire terminal, there is another reason, that is, when the power cord from the soldering iron heart terminal off, and then touched the grounding wire screw, resulting in the soldering iron head charged.
(2) this kind of failure, easy to cause electric shock accident, and will damage the components, in order to prevent the power cord off, need to regularly check the soldering iron handle on the pressure line screw whether there is loose and lost, such as loose, or lost, to match in time.
