Detailed Information
Safety Warning & Inspection Guidelines
To ensure safety, regular inspections must be carried out by professionals. Regular inspection must be carried out after the power supply of the distribution box and the unit are turned off to avoid causing electric shock, burns and other personal injuries. Because of the capacitor discharge, it is necessary to cut off the power supply of the welder and wait for 5 minutes before inspection.
All maintenance and repair work must be done with the power completely disconnected. Please make sure the power is unplugged before opening the housing. When the welder is energized, keep your hands, hair and tools away from the live parts inside such as fan in case of personal injury or damaging the welder.
