If we talk about the main methods of welding, then welding works with the use of solder, which melts and joins metal parts, differ. And without solder, when the weld is formed by melting the metal of those products that need to be welded. For welding in a domestic environment, the latter type is used, which can be divided into two main types. This is gas and arc welding.
For gas welding, gas types such as propane, acetylene and oxygen are used. In most cases, acetylene welding is used because this gas is not as explosive as liquefied oxygen. Propane is inferior to acetylene in its temperature characteristics, which is why the formation of the weld is longer and less durable. For gas welding, it is necessary to purchase a gas cylinder with a reducer that matches the type of gas, welding, surfacing or hardening torches and rubber hoses of the required length to connect the torch to the cylinder. Working with gas is always explosive and fire hazardous. Therefore, it is best to opt for high-quality equipment from such companies as Donmet, Vniyavtogenmash, Don or BAMZ, the quality of which corresponds to GOST and has proven itself over many years of work.
Electric welding machines are preferable to gas ones, as they give a better quality seam and less warp on the parts being welded. Electric welding is considered a safer way to weld parts compared to gas welding. This is because when using an electric inverter, there is only a danger of electric shock, not a fire or explosion of the gas cylinder. Purchasing a high-quality inverter eliminates the possibility of electric shock. Therefore, if you need to carry out welding work many times, it is best to buy a new inverter so as not to risk your health and electrical wiring when buying a used one.
If you need to carry out welding work in very small volumes, you can rent an inverter, but only in a reliable and proven organization. Now the most popular on the market are several foreign brands of inverter equipment. These are Kemmpi and Fubag, ProfHelper, Telwin and Brima. Among the lines of offered inverters, you can easily choose a device that will meet the necessary requests and parameters, and also will not leave your wallet empty.
