Welding machine electric shock protection device
Thread Content
Here, I would like to ask: when a welding machine is used in a humid environment or in a confined space, and if a leakage protector is installed at the power cable connection point of the welding machine, can this prevent construction workers from facing the risk of electric shock? What is the main reason? Also, I’m curious about the effectiveness of electric welder shock protection devices – could you recommend any reputable brands that have proven to be good?
In the case of electric shock on the AC side, a circuit breaker can provide protection by cutting off the power supply; however, it is likely to be ineffective in preventing electric shock during DC welding
If the welder’s casing leaks electricity, the circuit breaker will activate. I mainly want to know whether an electric shock accident can occur during welding, for example, when a person touches or comes into contact with the welded parts or the welding torch due to sweating, humidity, and other reasons
Then you must be referring to the DC side. As long as no illegal operations are carried out, there should be no problems, because the voltage on the AC side is relative to ground, not to the grounding point. As long as you don’t place your hand between the welding torch and the grounding point, there should be no issues
During use, the welder’s enclosure is required to have a good grounding point. .
