The electric welder provides the possibility of achieving a good finish in metal joining jobs, with better results than those carried out by other methods. Soldering accessories can be found in supermarkets, hardware stores, and other similar stores since it is widely used and highly commercialized in the market. Electric soldering is used to join materials, especially metal, by the heat generated by electrical energy.
Normally it is recommended to use a low-power soldering iron with precision tweezer (to grasp the object) so that the electrical circuits are not damaged. As for the types of welders, they depend on the characteristics of the work to be done. There are various types of electric welders.
Types of Electric Welders
The welding equipment has some generators (known as groups), to be able to regulate the intensity of the voltage with which it is planned to work. You can learn more about it on ratemywelder.com.
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 pieces of equipment. One of the parts to be welded is connected to the ground, while the electrode carries a positive charge.
Submerged Arc Welder: This type of welder uses wire instead of electrodes (MIG-semiautomatic), an inert gas to join the parts. The piece with which it is welded is immersed in the middle of a continuous stream of granulated material called flux, which completely covers the arc. Its main function is to protect the weld from oxidation.
Bare Electrode Arc Welder in Controlled Atmosphere: This last method uses an arc system together with a gas that protects the part from oxidation. It can be carried out with consumable Tungsten electrodes, or TIG, which can be with or without contribution. The gas that is used the most is argon since it is very specific for certain welds.
Electric temperature welders:
Electric soldering iron: The electric soldering tin, tin used to join two metal parts. It melts at a very low temperature, around 250 ° C, and when the tin cools it takes shape, thus joining the two parts. The tin soldering iron is made up of a copper tip (through which heat is transmitted) and an electrical resistance, which generates the temperature to heat the two parts to be assembled by soldering and melting the tin. There are two types of electric soldering irons for melting tin: slow electric soldering iron and fast electric soldering iron.
The slow electric welder is the most usual. It is made up of a bronze tip, an electrical resistance, plastic or wooden handle, and a cable for its electrical connection. It reaches 400 to 450 ° C. It takes a few minutes to achieve this temperature, while the fast electric soldering iron can 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 soldier’s area. Its consumption is around 100 watts.
