Electrical contact protection for welding circuits
Electrical contact protection in welding circuits limits the open-circuit voltage to prevent fatal shocks. This is done through built-in voltage reduction devices.
Physical-Chemical Mechanism of Action
The open-circuit voltage in welding circuits can be dangerous, especially in damp environments. Electrical contact protection devices reduce this voltage to safe levels through built-in reduction components.
Metallurgical Relevance & Welding Risks
Excessively high open-circuit voltage can cause fatal shocks, especially if the weld comes into contact with wet ground or other conductive materials. This increases the risk of serious injury and fatal accidents.
Workshop Practice & Action Guidelines
Use welding machines with built-in electrical contact protection. Ensure the reduction device is correctly activated and functioning. Regularly check voltage readings and perform necessary maintenance.
