The electric welder It provides the possibility of achieving a good finish in metal joining works, with better results than those carried out using other methods. This tool can be found in supermarkets, hardware stores and other similar stores, since it is widely used and highly commercialized in the market. The electric welders They are used to join materials, especially metallic ones, by means of the heat generated by electrical energy.
It is usually recommended to use a welder of low power, so that the electrical circuits are not damaged. As for the types of weldersdepend on the characteristics of the work to be done. There are various types of electric welders.
Types of Electric Welders
Welding equipment has generators (known as groups), to be able to regulate the intensity of the voltage with which it is planned to work.
Electric arc welders:
- Electrode welder: It is one of the most common welders. To achieve welding, rods called electrodes are used, through which the current passes and the arc is generated, melting the electrode. It is one of the cheapest equipment. One of the parts to be welded is connected to ground, while the electrode carries the positive charge.

- Submerged Arc Welder: This type of welders uses wire instead of electrodes (MIG-semi-automatic), and inert gas (CO2, atal, arcal, etc.) to join the parts. The piece with which it is welded is submerged in the middle of a continuous stream of granulated material called flux, which completely covers the arc. Its main function is to protect the solder from oxidation.
- Arc Welder with Bare Electrode in Controlled Atmosphere: This last method uses an arc system together with a gas that protects the piece from oxidation. It can be done with consumable Tungsten electrodes, or TIG, which can be with or without input. The gas that is most used is argon, since it is very specific for certain welding.
Temperature electric soldering irons:
- Electric tin soldering iron: The electric tin soldering ironsThey use tin to join two metal parts. It melts at a very low temperature, around 250°C, and when the tin cools it takes shape, thus uniting the two parts. The tin welderIt is formed by a copper tip (through which the heat is transmitted) and an electrical resistance, which generates the temperature to heat the two parts that are to be assembled by soldering and melting the tin. There are two types of electric welders to melt tin: slow electric welder Y fast electric welder. The slow electric welderis the most usual. It is made up of: a bronze tip, an electrical resistance, a plastic or wooden handle and the cable for its electrical connection. It reaches 400 to 450°C. To achieve this temperature, it takes a few minutes. fast electric welderinstead, it manages to reach 450° – 500° C in just a few seconds. They are shaped like a pistol and work by pulling a trigger. They are generally provided with a lamp, which illuminates the welding area. Its consumption is around 100 watts.
Maintaining safety standards is always the main thing for this type of work.
