Different Types of Electric Welders
The electric welder provides the possibility of achieving a good finish in metal joining work, with better results than those performed by other methods. This tool can be found in supermarkets, hardware stores, and other similar stores, as it is widely used and highly marketed in the market. Electric welders are used to joining materials, especially metals, through the heat generated by electrical energy.
It usually is recommended to use a low power soldering iron so that the electrical circuits are not damaged. As for the types of welders, they depend on the characteristics of the work to be carried out. There are several types of electric welders.
Types of Electric Welder
The welding equipment has generators (known as groups), to be able to regulate the intensity of the voltage with which it is planned to work.
It is one of the most common welders. In achieving welding tasks, rods called electrodes are used, through which the current passes and the arc is generated, melting the electrode. It is one of the most economical equipment. One of the parts to weld is connected to earth, while the wire carries the positive charge.
Submerged Arc Welder
This type of welder uses wire instead of electrodes (MIG-semi-automatic), an 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 a granulated material called flux, which completely covers the arc. Its primary function is to protect the weld from oxidation.
Arc Welder with Naked Electrode in Controlled Atmosphere: This last method uses an arc system together with a gas that protects the part from oxidation. It can be done with consumable Tungsten or TIG electrodes, which can be with or without filler. The gas most commonly used is argon, as it is precise to certain welds.
Tin Electric Welder
Tin electric welders use the tin to join two metallic parts. It melts at a very low temperature, about 250°C. When the tin cools, it takes on the body, thus joining the two parts. The tin solder consists of a copper tip (which transmits heat) 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 welders to melt tin: slow and fast electric welder. The slow electric welder is the most usual. It is composed of: a bronze tip, an electric resistance, a plastic or wooden handle and the cable for its electrical connection. It reaches 400 to 450°C.
In achieving this temperature, it takes a few minutes. The fast electric welder, on the other hand, manages to reach 450° - 500° C in only a few seconds. They are pistol-shaped and work by pulling a trigger. It usually comes with a lamp that illuminates the soldier's area. Their consumption is around 100 watts.
