Temperature-regulated soldering iron does not heat up the reason
When the soldering iron is energized, found that the soldering iron head is not hot, generally the power cord is off or the core wire of the soldering iron is broken. Encounter this fault can be used multimeter Rxlk block measurement of power plug ends, if the multimeter pointer does not move, that there is a broken circuit fault.
First of all should check the plug itself leads have no broken phenomenon, if not, then you can remove the rubber wood handle, and then use the multimeter to measure the two leads of the soldering iron core, if the multimeter pointer is still not moving, that the soldering iron core is damaged, should be replaced with a soldering iron core. 35W endothermic soldering iron core between the two leads of the resistance value of the force of 1.SkQ or so, if the measured resistance is normal, then the iron iron is a good iron core, the fault occurs in the power supply leads and Plug itself, most of the fault for the lead break.
Replacement of the soldering iron core should be new with the specifications of the soldering iron core inserted into the connecting rod, the lead is fixed in the set screw, and tighten the terminals, at the same time, pay attention to the soldering iron core lead to the excess part of the cut off, in order to prevent the two leads from short-circuiting.
Troubleshooting power cord and plug. So when you encounter the soldering iron is not hot, use a multimeter to check the power plug and power cord first, and then check the soldering iron core after exclusion.
How to clean the head of the soldering iron
1, soldering iron head cleaning sponge with too much water, the temperature of the iron will fall rapidly, tin slag is not easy to fall off, not enough water when the sponge will be burned off. The principle of cleaning: when the right amount of water, soldering iron head contact instant, the water will boil fluctuation, to achieve the purpose of cleaning.
2, the soldering iron head must be uniformly left tin, so that tin will take part of the heat and ensure that the soldering iron head is not oxidized by the air, to extend the life of the soldering iron has the advantage. Do not leave a residual tin and turn off the power, the temperature slowly decline, thermal oxidation will occur to reduce the life of the iron!
Use soldering iron head cleaner
1、Clean soldering iron head is simple and convenient. Quite a few cleaner with anti-static function (does not come with a ground wire 0 mute design to save energy only 5W power consumption (with AC adapter))
2, to prevent solder splash, internal sealing design can avoid cleaning the soldering iron head when the solder splash everywhere, effectively reduce the production scrap rate; cleaning action of all internal sealing, to prevent solder splash.
3、Reduce the temperature drop of the soldering iron head cleaning brush without adding water to use, cleaning can reduce the temperature drop of the soldering nozzle, so that the soldering iron head often to maintain high working efficiency.
