1. The chassis of the butt welding machine must be grounded. The purpose of grounding is to prevent the butt welding machine from accidentally touching the shell and injuring people. It is indispensable under any circumstances. The grounding body of the butt welding machine can widely use the natural grounding electrode. However, it is strictly forbidden to use the pipeline of inflammable 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. The production requirements of the butt welding machine are strictly prohibited to use the electric welding tongs without a shell to prevent accidents.
3. The staff must wear gloves when changing 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 disconnect the power switch when repairing the butt welding machine, 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 maintenance.
5. When the butt welding machine is moving, the power supply 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 welding machine is working, the power supply should be cut off immediately to prevent electric shock caused by a sudden point.
