According to the safety regulations and standards of China, the leakage protector is a compulsory safety equipment and must be used in some cases. For example, in industrial and construction sites, equipment using three-phase power supply must be equipped with leakage protectors to ensure the safety of personnel and equipment.
When connecting the leakage protector, pay attention to the following points:
The rated current of leakage protector should match the rated current of welding machine.
The leakage protector should be able to withstand the starting current of the welding machine to avoid triggering the leakage protector by mistake.
The earth leakage protector should be correctly wired, and it needs regular inspection and maintenance to ensure its normal operation.
In a word, connecting the leakage protector can improve the safety performance of the welding machine, but before connecting, it is necessary to carefully understand the use requirements of the leakage protector and the characteristics of the welding machine to ensure correct installation and avoid faults.
