Question:

The argon arc welding machine ground wire will leak, what's the matter, looking for a long time can not find the reason, have been it several times

The argon arc welding machine ground wire will leak, what's the matter, looking for a long time can not find the reason, have been it several times

Answer:

Reason:High frequency electricity, pay attention to cleaning the dirt at the interface, arc when the tungsten is not too far away from the workpiece.High frequency electricity:The high frequency current is the current relative to the power frequency 50HZ alternating current. For example, the carrier current in a communication signal is a high frequency current. In some cases, in order to change the speed of the motor, it is necessary to use a converter to change the power frequency current into a relatively high frequency current, also called a high-frequency current. High frequency currents sometimes have an obvious radiation effect and can even cause harm to humans. Of course, some less powerful high-frequency currents do no harm to the human body. One important characteristic of high frequency currents is the skin effect, such as a solid conductor, which usually runs on its surface instead of the entire conductor. In comparison with the power frequency current, a characteristic of the high-frequency current is that the fatality rate will decrease after the electric shock, and the higher the frequency, the lower the fatality rate. The alternating current above 20000 Hz is a high frequency current.
Your earth is not grounded, instructions should have positive ground requirements, if the ground, to see whether the welding poor insulation, ignition by high voltage pulse breakdown voltage protection gas ignition, about three thousand, is the General Electric will be pitted, not life-threatening
Your welding gun is not insulated well
