1. The housing of the butt welding machine must be grounded. The purpose of grounding is to prevent the butt welder from accidentally hitting the shell and hurting people with electricity. It is indispensable under any circumstances. The grounding body of the butt welding machine can widely use the natural grounding electrode, but it must be strictly prohibited to use the pipeline of combustible and explosive materials as the natural grounding body. If the resistance of the natural grounding electrode exceeds 4Ω, it is best to use an artificial grounding body, otherwise, it is likely to cause an electric shock accident or even a fire.
2. The insulation of the welding tongs of the butt welding machine must be reliable, and it is strictly forbidden to use the welding tongs without shell in the production requirements of the butt welding machine to prevent accidents.
3. The staff must wear gloves when replacing the welding rod. If the clothes are soaked with sweat, they are not allowed to lean on metal objects to prevent electric shock.
4. The construction personnel must turn off the power switch when repairing the butt welder, and the switch must have an obvious disconnection gap. Finally, use an electric pen to check to ensure that the power has been cut off before starting the repair.
5. When the butt welding machine is moving, the power must be cut off, and it is not allowed to move the butt welding machine by pulling the cable.
6. If there is a sudden power failure when the butt welder is working, the power supply should be cut off immediately to prevent sudden electric shock.
