Soldering gun: operating principle, how to choose, precautions

The basic rule of soldering is based on the fact that the maximum temperature is reached at the tip of the soldering iron, which can melt the solder and heat up the connected elements. Over time, in order to reduce the heating time of the device, thereby saving energy, energy-saving models were invented - soldering guns, which received the scientific name pulsed soldering irons.

Product Description

The most important element of the soldering gun is the rod, which is in direct contact with the molten parts, so it is called a sting. It is fixed in a metal tube around which there is a heating element. The whole structure is located in the housing, which has a handle with which the device is held in the hand.

So that the heating element does not melt the body, it is wrapped with insulating material - mica or fiberglass.

On the reverse side there is a hole for the wire, it is through it that an electric current passes to power the device. The holder is most often made of wood or heat-resistant plastic. In the photo - a factory-made soldering gun.

Principle of operation

The soldering gun has a very simple operating principle. When you turn on the product in a normal outlet, the current passes to the heating element, thereby emitting a large amount of heat that is transferred to the sting, heating it to 350 degrees Celsius.

Areas of use

In the modern world, a soldering gun is widely used. Depending on the power, it is used in different areas:

• a low-power device (up to 40 W) is used for soldering electronics;
• in their work, electricians and electricians daily use a solder product;
• used in production, in workshops, at home, to connect electrical and piping;
• in factories according to the invention of microcircuits;
• soldering machines with a power of 100 watts or more are used for tinning large parts.

Product Selection Criteria

There are a lot of models of soldering guns on the modern market - from the simplest and cheapest devices to expensive designs. It is imperative to know what parts will need to be soldered:

1. In everyday life, they usually use the traditional model - 25-40 watts to lengthen the wire or repair the antenna connector.
2. To work with large parts (radiators, resistors), it is recommended to use products with a power of more than 100 watts.
3. In the selection should pay attention to the shape and material of the tip. Copper stings are preferred, as they are easier to clean.
4. Product dimensions are also an important point. It is worth considering that large models will be difficult to hold for a long time in the hand.
5. If the device will be used for soldering chips, it is better to choose a gun with a power of up to 20 watts. Their kit, as a rule, includes a set of thin stings. It is better if the model is with a temperature control function.

Precautionary measures

Before starting use, you should prepare a workplace, as well as clearly observe the rules for using the product:

1. Before turning on, you need to check the sting. It must be clean, dry and free from corrosion.
2. It is forbidden to lower the working device into water - this threatens with electric shock. In addition, the product will be irretrievably broken, which will lead to new expenses.
3. A blow gun is a fire hazard. Disconnect the device from the power outlet at the end of work.
4. It is necessary to ensure that the heated sting does not come into contact with its wire and others.
5. Put the product only on the stand, as the gun may roll.
6. Keep the working tool only by the handle.
7. At the end of work, turn off the device, allow to cool and ventilate the room.

Consumers who have already used it leave positive feedback. A soldering gun is a modern device, it is much more convenient than a traditional soldering iron.
