1. The operator of the PE pipe welding machine must be specially trained by the relevant department and pass the examination before taking up the post. Use by non-operators is strictly prohibited.
2. The electrical and control parts of the PE pipe welding machine are not waterproof, and water should not be allowed to enter the electrical and control parts of the PE pipe welding machine during operation and use. In case of construction in rainy weather, protective measures should be taken for the electrical and control parts of the PE pipe welding machine.
3. When the PE pipe welding machine is welding below zero, appropriate protective measures must be taken to ensure that the welding surface has sufficient temperature.
4. All items in contact with the welding surface must be clean. The welding surface must be clean and dry before welding. The parts that need to be welded must not have damage, impurities, or dirt (such as dirt, grease, chips, etc.).
5. To ensure the continuity of the welding process, sufficient natural cooling should be carried out after the welding is completed to eliminate its internal stress.
6. For piping components with dn≤63mm or wall thickness e<6mm, it is not allowed to use hot-melt butt welding.
7. When the pipe components of different SDR series are welded to each other, it is recommended to use electrofusion connection or adopt appropriate processing methods to make the welded joints have the same wall thickness.
8. When using a PE pipe welding machine for welding, each weld should have a detailed original welding record. The original welding record should at least include weather conditions, ambient temperature, welder code, weld number, pipe specification type, welding pressure, and drag pressure , Pressurization time, heating plate temperature, switching time, heat absorption time, cooling time, etc.
9. It is strictly forbidden to increase or decrease the fuse in the fuse of the PE pipe welding machine.
10. During use, the operating conditions of the PE pipe welding machine should be observed at any time. If there is abnormal noise or overheating, it should be stopped immediately.
11. The PE pipe welding machine should be kept clean at all times to prevent dust accumulation and circuit failure.
