Careless handling of a soldering iron ends in household injury, damage to furniture and clothing. If you don’t follow basic safety precautions, you could end up breaking an electrical appliance that needed repair, or making a shoddy, horrendous seam. Anyone who is going to weld should know what to avoid when an electrical device with a hot tip is in his hands. This article talks about the main mistakes made by the owners of soldering irons of old and new models.

Knocking on the table and swinging the soldering iron

Modern soldering tools have ceramic heating elements, so if hit hard they will crack and fail. Mechanical shocks can be detrimental to a modern instrument.

If you feel like brushing the soldering tip, stop. The molten fragment can enter the eye, on the skin or fall where it is then picked up by children or animals. A drop of hot flux can damage the surface of furniture, burn clothes or the floor.

Use a soldering iron to strip the PVC wires

To save a few minutes on the removal of PVC insulation, some budding craftsmen prefer to solder it with a soldering iron.

Never repeat these mistakes, otherwise you risk damaging the cores of the cables and sticking plastic between them that cannot be removed. To avoid problems in the future when tinning the wire, use a professional wire stripper or a regular sharp knife and pliers.

Weld under voltage

You should never start repairing electrical devices without making sure they are completely de-energized. Before turning on the soldering iron and starting to work, carefully inspect the device being repaired. According to the type of power supply:

  • unplug the power cord;
  • remove batteries and accumulators;
  • de-energize the non-removable battery to “zero”.

Pay attention to the presence of batteries. Even though the device is powered by 220W, it may contain batteries.

If the puncture reaches the current-carrying part, a short circuit will occur, which will ultimately destroy the repaired device and disable the soldering iron.

Do not tin the tip before working with a new soldering iron

A new electric soldering iron with a clean, shiny tip won’t do. In order for the tip to be soldered with high quality, it must be tinned with an even layer of solder. Therefore, before you start welding, prepare the device for work.

Owners of older models also need to tinker with a sting. Experienced craftsmen prefer copper tips, which are undermined with a file or sandpaper. After such treatment, the sting must be treated with solder.

Always work at the highest temperature

Most modern soldering irons have a temperature control feature. Many users believe that the higher its value, the better. They are delusional.

Exceeding the temperature regime threatens too rapid wear of the tip and the tool.

To set the temperature correctly, you need to familiarize yourself with the characteristics of soldering and set the value, focusing on each specific case.

To increase the life of the soldering iron, it is recommended to adjust the settings more often, adding an additional 50 degrees C to the degrees of solder fusion.

The smooth operation of the soldering iron allows you to enjoy the self-repair of electrical appliances, do not hurt yourself or others, do not spoil clothes, furniture, and extend the service life of the soldering iron. ‘tool.
