An electric welding machine refers to an electrical device that provides a certain characteristic power source for welding. Its working principle is that when it comes into contact with the welded object and the welded object, a short circuit occurs, which generates a high-temperature arc and melts the welded object, causing them to fuse with each other. Welding machines are divided into household welding machines and industrial welding machines.

Home type welding machine: Designed for practical use in households, it mainly uses a mixed type of argon arc welding and cold welding. Its characteristics include low power and a power supply voltage of 220V.

Industrial welding machine: designed for industrial practicality, with high power and a general power supply voltage of 380V/220V. Wide welding range, can work continuously for more than ten hours without stopping. High reliability and powerful heat dissipation function ensure that the equipment can withstand high loads and harsh working conditions.
