What problems are present in most electric soldering irons?
1. After being turned on, the electric soldering iron does not heat up.
When a soldering iron is turned on but does not immediately begin to heat up, an open circuit fault is present. There are various locations at the soldering iron plug where this flaw could develop. All three components of the soldering iron are damaged: the power cord, the lead wire, and the soldering iron core.
2. The soldering iron's tip does not consume tin.
Do not consume the soldering iron tip. Tin Pu observes that the freshly purchased soldering iron tip is used without trimming, preventing the soldering iron tip from being tinned. It is necessary to fix the burnt-to-death soldering iron tip that has been in use for a long time because it is not tinned.
3. A charge is applied to the soldering iron.
For welders, using an electric soldering iron poses a severe risk of electric shock mishaps. Therefore, the power supply should be shut off right away for inspection once it is discovered that the electric soldering iron is electrified. The electric soldering iron is electrified for a number of reasons. The electric soldering iron's power cord is attached to the grounding wire's terminal; when the power cord separates from the soldering iron core's terminal, it touches the grounding wire's screw, tangles the soldering iron's electric power lead wire, and causes leakage; the power ground itself conducts electricity.
4. The soldering iron's tip has a pit in it.
Long-term usage of the electric soldering iron causes the soldering iron tip to develop pits or oxidized corrosion layers, which alter the soldering iron tip's blade surface's shape. In this situation, the oxide coating and pits can be removed with a file, the item can be reshaped, tinned, and then utilized again.
(2) Before measuring the two lead wires 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 internal heating 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.
Live iron head upkeep strategy (1) In addition to the power line's improper connection to the grounding line terminal, another factor that contributes to the soldering iron tip becoming electrified is the power line's repeated contact with the grounding line's screw when it detaches from the soldering iron core's terminal. 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.
