Electrical safety protection
1. Grounding protection: The welding machine should be placed indoors and should have reliable grounding or zero connection.
2. Leakage protection: When used in a humid environment or metal structure, a leakage protector should be installed.
3. Overload protection: It has an overload protection function. When the equipment load exceeds the rated value, the power supply is automatically cut off.
Operation safety protection
1. Emergency stop function: It is equipped with an emergency stop button. Once an emergency occurs, the operator can quickly press the button to stop the welding process immediately.
2. Automatic detection and alarm: It has the function of automatically detecting open and short circuit faults of the welding circuit, temperature sensor faults, etc., and can send out an alarm signal when an abnormality is detected.
3. Operation error prompt: It can automatically detect operation errors and prompt through the screen to avoid safety accidents caused by misoperation.
4. Protective device: When the welding equipment is used outdoors, a machine shed should be set up to prevent rain and moisture, and keep it ventilated and dry.
Environmental adaptability protection
1. Temperature compensation function: Automatically adjust welding parameters according to ambient temperature to ensure the best welding effect at different ambient temperatures.
2. Waterproof and moisture-proof design: Although the electric fusion welding machine itself does not have waterproof performance, the design takes moisture-proof requirements into consideration to adapt to harsh conditions in the field.
Other safety protections
1. Fan protection: The built-in fan is used for heat dissipation to prevent the equipment from overheating. If the fan does not turn, the equipment will automatically stop working.
2. Data storage and traceability: Important parameter data during the welding process are recorded and stored in real time, which is convenient for later traceability and analysis to ensure welding quality.
3. Automatic protection function: It has automatic voltage stabilization and power supply voltage over-limit protection functions.
4. High-temperature component protection: The maximum temperature of the heating plate can reach 250℃. Operators should use handles when extracting the heating plate to avoid direct contact with high-temperature components.
5. Welding surface cleaning: Before welding, the oxide layer on the outer surface of the pipe molten zone and the inner wall of the pipe fitting must be completely removed, otherwise it will affect the welding quality and cause safety hazards.
6. Cooling protection: After welding, the joint should be in a natural state during the cooling process, and it should be ensured that no external force is applied during the cooling process. The joint part and the pipes on both sides should not be moved or rotated.
7. Install the centralizer: When welding large-diameter pipes and pipe fittings, it is advisable to install centralizers, tensioners, hand winches and other tension devices to prevent the displacement of the pipe interface during welding.
8. High temperature weather protection: When the temperature exceeds 30℃ and the electrofusion pipe welding occurs with grouting, the subsequent welding time should be reduced by 10%.
9. Power cord requirements: The socket line of the welding machine is more than 4 square meters, and the power cord of at least 6 square meters is required for a length of more than 50 meters.
10. Pressure test protection: In high temperature weather, the pressure test work should be arranged as early as possible in the morning and evening. After the pipeline to be tested is installed, the pipe body should be covered with soil to expose the connection for observation, so as to reduce the tensile damage to the pipes and fittings caused by thermal expansion and contraction.
