Why is the welder not grounded to work properly?
Dec 21, 2018

The grounding of the welding machine is mainly to prevent the electric leakage of the welding machine and cause the electric shock accident of the welding personnel, in order to ensure safe production. When the welder is not grounded, if the welder has poor insulation and generates electric leakage, if a person touches the welder and has more than 0.05 amps of current passing through the human body, there is a danger to life. Therefore, the electric welder must be grounded before use, so that the equipment and the earth can form a loop. When the human body contacts the welder, the current will not pass through the human body, thus preventing the occurrence of an electric shock accident.


1、The electric welder uses the high-temperature arc generated by the positive and negative poles in an instantaneous short-circuit to melt the solder and the material to be welded on the electrode to combine the objects to be contacted. Its structure is very simple, it is a high-power transformer.

2、Electric welding machines are generally divided into two types according to the type of output power, one is AC power and the other is DC. They use the principle of inductance, the inductance will produce a huge voltage change when it is turned on and off, and the high-voltage arc generated by the positive and negative poles in the instant short circuit is used to melt the solder on the electrode to make them achieve atomic bonding. .

3、Advantages of electric welding machine: Electric welding machine uses electric energy to convert electric energy into heat energy instantaneously. Electricity is very common. Electric welding machine is suitable for working in dry environment. It does not require too much demand. It is compact in size, easy to operate, easy to use, and speed. Faster, the weld is strong after welding and so on. It is widely used in various fields. It is especially practical for parts with high strength. It can instantly connect the same metal material (you can also connect dissimilar metals, but the welding method is different). The joints, after the heat treatment of the welds, have the same strength as the base metal and are well sealed, which solves the problem of sealing and strength for the manufacture of storage gas and liquid containers.
