1. Before using the butt welding machine, check that the extra voltage and the power supply voltage winding are together (380 v or 380 v), and check that the terminal connection is correct. If it is the first time to put into operation or stop using the bright light butt welding machine for a long period of time, the center of the winding insulation resistance should be measured with a 500 v megohmmeter and Ω should not be less than 0.5 meters before use.

2. Nuts, copper lugs and cables on the primary and secondary sides of the butt welder must be firmly connected. If the contact is not good, bolts, nuts and ring lugs can be used. Therefore, after a period of operation, the welding machine will come into contact with the fine emery cloth to clean the bolt connection on the surface of the oxide layer.

3. The welding rod and the welding part of the butt welding machine should avoid long-term short circuit and avoid burning the welding machine.

4. The working place of the butt welder should be dry and well ventilated. Move the welding machine, cut off the power supply, and do not use the method of dragging the cable to move the welding machine and other welding.

5. If you need to work with multiple butt welders at the same time, it should use the three-phase welding machine evenly, and the three-phase load balance.

6. It is necessary to ground the shell of the welding machine, use a wire to connect to the main ground and continue to be alone. Multiple connections with the grounding device, the welding machine series adopt a parallel method, which is prevented. When the welding operation is not over, instead of removing the ground wire randomly.

7. The butt welding machine cannot be operated under high humidity (relative humidity above 90%), high temperature (over 40°C), and no ventilation, and stay away from flammable and explosive. The welding machine is placed steadily, and severe vibration and hitting should not be avoided to avoid damage to the reactor performance and make the welding machine unable to operate normally. The welder should be clean and dry, and low-pressure dry compressed air should be used for regular finishing operations.

8. If the butt welder is overheated, the welding arc, the winding current cannot be adjusted, the excessive vibration or noise fails on the machine, it should be stopped, the cause should be found, and the treatment should be maintained.
