The basic rule of soldering is based on the fact that the tip of the soldering iron reaches the maximum temperature that can melt the solder and heat the elements to be joined. Over time, in order to reduce the heating time of the device, thereby saving electricity, energy-saving models were invented - soldering guns, which received the scientific name of impulse soldering irons.
Instrument description
The most important element of a soldering gun is the rod, which is in direct contact with the parts to be melted, which is why it is called the tip. It is fixed in a metal tube, around which there is a heating element. This whole design is in a case with 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 forwires, it is through it that the electric current passes to power the device. The holder is most often made of wood or heat-resistant plastic. The photo shows a factory-made soldering gun.
Working principle
The soldering gun has a very simple principle of operation. When the product is plugged into a regular socket, the current flows to the heating element, thereby releasing a large amount of heat, which is transferred to the tip, heating it up to 350 degrees Celsius.
Applications
In the modern world, the soldering gun has found wide application. Depending on the power, it is used in different areas:
- device of low power (up to 40 W) is used for soldering electronics;
- electromechanics and electricians use a soldering product in their daily work;
- used in manufacturing, workshops, at home to connect electrical and pipelines;
- in microchip factories;
- soldering machines with a power of 100 W or more are used for tinning large parts.
Criteria for product selection
There are a lot of models of soldering guns on the modern market - from the simplest and cheapest devices to expensive designs. It is paramount to know which parts will need to be soldered:
- In everyday life, they usually use the traditional 25-40W model to extend the wire or fix the antenna connector.
- To work withlarge mass parts (radiators, resistors), it is recommended to use products with a power of more than 100 W.
- In choosing, you should pay attention to the shape and material of the tip. Copper tips are preferred as they are easier to clean.
- Product dimensions are also an important point. It should be borne in mind that large models will be difficult to hold for a long time in the hand.
- 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 temperature control function.
Precautions
Before starting use, you should prepare the workplace, and strictly follow the rules for using the product:
- Before switching on, you need to check the sting. It must be clean, dry and free from corrosion.
- Do not immerse the operating appliance in water - this threatens with electric shock. In addition, the product will be irreparably broken, which will lead to new expenses.
- A soldering gun is a fire hazard. You should unplug the device from the outlet at the end of work.
- It is necessary to ensure that the heated tip does not come into contact with its wire and others.
- Place the product only on the stand, as the gun may roll.
- Hold the working tool only by the handle.
- At the end of work, turn off the device, let it cool down and ventilate the room.
Consumers whohave already used it, leave positive feedback. The soldering gun is a modern device, it is much more convenient than a traditional soldering iron.
