As a common soldering tool, the soldering iron is widely used in the field of electronic production and maintenance. However, during long-term use, the soldering iron may encounter some malfunctions. The following will introduce some common malfunctions of soldering irons and their identification and treatment methods in detail.

I. Common Malfunction One: The soldering iron does not heat up or does not heat up enough.

Identification Method:
– After plugging in the power, the soldering iron tip does not heat up significantly.
– When soldering, the solder is not easy to melt.

Possible Reasons:
1.The power cord or plug is damaged.
2.The soldering iron core is aging or damaged.
3.The temperature controller malfunctions and cannot correctly control the temperature.

Treatment Methods:
– Check the power cord and plug to ensure good connection and no damage.
– Replace the soldering iron core to ensure its normal operation.
– Repair or replace the temperature controller.

II. Common Malfunction Two: Excessive oxidation or erosion of the soldering iron tip.

Identification Method:
– Black oxides or erosion marks appear on the surface of the soldering iron tip.
– The heat conduction performance of the soldering iron tip decreases, and the soldering effect is not good.

Possible Reasons:
– Used at high temperatures for a long time without proper maintenance.
– Low-quality solder or flux is used.

Treatment Methods:
– Regularly clean and polish the soldering iron tip to remove oxides.
– Choose a suitable temperature and soldering time during use to avoid long-term heating at high temperatures.
– Use high-quality solder and flux.

III. Common Malfunction Three: The soldering iron leaks electricity.

Identification Method:
– There is a slight sensation of electric shock during use.
– The insulating part of the soldering iron is damaged or aged.

Possible Reasons:
– The insulating material inside the power cord or soldering iron is aging or damaged.
– The soldering iron is poorly grounded.

Treatment Methods:
– Immediately stop using it, check the power cord and the insulating part of the soldering iron, and replace them if necessary.
– Ensure that the soldering iron is well grounded to reduce the risk of electric leakage.

IV. Common Malfunction Four: The temperature controller is malfunctioning.

Identification Method:
– The temperature of the soldering iron cannot be stably controlled.
– The temperature is too high or too low to meet the soldering requirements.

Possible Reasons:
– The internal components of the temperature controller are aging or damaged.
– There is a deviation between the temperature set by the temperature controller and the actual temperature.

Treatment Methods:
– Replace the temperature controller.
– Recalibrate the temperature controller to ensure its accuracy.

V. Common Malfunction Five: The soldering iron tip does not stick to the solder.

Identification Method:
– The solder cannot be evenly applied on the soldering iron tip.
– The solder is easy to fall off during soldering.

Possible Reasons:
– The surface of the soldering iron tip is not clean, with oxides or impurities.
– The temperature of the soldering iron tip is too high or too low.

Treatment Methods:
– Clean the impurities and oxides on the surface of the soldering iron tip.
– Adjust the temperature of the soldering iron tip to a suitable soldering temperature.

VI. Summary

The soldering iron may encounter various malfunctions during use, which not only affects the soldering quality but also poses a threat to the operator’s safety. Therefore, users should regularly inspect and maintain the soldering iron to ensure it is in good working condition. Meanwhile, for malfunctions that cannot be handled independently, users should contact professionals for repair in a timely manner to avoid potential safety hazards.
