[0002] Welding is a welding method that achieves atomic bonding between two weldments by heating, pressurizing or both. Welding can be seen everywhere in our daily life, and the price of welding machines is becoming more and more popular; in electric welding When the device is just switched on, the arc is often unstable, and the current is also unstable at this time, which may cause the phenomenon of excessive current. Excessive current may cause the electrical parts in the welding device to burn out, and the size of the welding current The sudden change will also directly affect the stability of the arc, welding quality and weld formation

The invention discloses an electric welding device with electric protection. The device includes an electric protection circuit, a magnetic coil, a welding gun, and an electric conductor. The weldinggun, and the electric conductor are connected with a second connecting part of the magnetic coil separately, the electric protection circuit is connected with a first connecting part of the magnetic coil, and the electric protection circuit is used to slow down the power supply speed of a power source to the magnetic coil. According to the device, the structure is simple, wires with magnetism areutilized to make a coil, a magnetic core is omitted, the weight is comparatively light, the carrying and use are convenient, meanwhile the electric protection circuit is arranged and can be used to slow down the power supply speed, and over-large making current is prevented after the power source is switched on, so that electric parts in the electric welding device are prevented from being burnedout, and the service life of the electric welding device is prolonged.
