The operating procedures are as follows:

1, argon arc welding must be operated by special personnel switch.

 2. Check whether the equipment and tools are good before work.

 3. Check the welding power supply, whether the control system has ground wire, and add lubricating oil to the transmission part. For normal rotation, argon and water must be unblocked. In case of water leakage, call for immediate repair.

 4. Check whether the welding gun is normal and the ground wire is reliable.

 5. Check whether the high-frequency arc starting system and welding system are normal, whether the wire and cable joints are reliable, and whether the adjusting mechanism and wire feeding mechanism are in good condition for automatic electrode argon arc welding.

6, according to the material of the workpiece to choose polarity, good welding circuit, general material with DC positive connection, aluminum and aluminum alloy with reverse connection or AC power supply.

7, check whether the welding groove is qualified, the surface of the groove shall not have oil, rust, etc., on both sides of the weld within 200mm to remove oil and rust.

8, for the use of fetal gear to check its reliability, the welding parts need to preheat also check the preheating equipment, temperature measuring instrument.

9. The control button of argon arc welding shall not be far away from the arc, so that it can be closed at any time in case of failure.

10, the use of high frequency arc must often check whether there is leakage.

11, equipment failure should be power off maintenance, operators shall not repair themselves.

12, in the vicinity of the arc is not allowed to naked and naked storm other parts, not allowed to smoke and eat near the arc, so as to avoid ozone, smoke inhalation in the body.

13. Wear mask and gloves when grinding thorium tungsten electrode, and abide by the operating rules of grinder. The best choice is cerium tungsten pole (less radioactive). The grinder must be equipped with a suction device.

14. Operators should wear electrostatic dust masks at all times. Minimize the high frequency electrical action time during operation. Continuous work shall not exceed 6 hours.

15, argon arc welding work site must be air circulation. Ventilation and detoxification equipment should be activated during work. When the ventilation device fails, it should stop working.

16. Argon gas bottle is not allowed to be smashed, and must be placed with a support, and away from the open flame more than 3 meters.

17. When argon arc welding is carried out inside the container, a special mask should be worn to reduce the inhalation of harmful smoke. The vessel should be monitored and coordinated by a person outside.

18. Thorium tungsten rods should be stored in lead boxes to avoid injury due to the concentration of a large number of thorium tungsten rods, the radioactive dose beyond the safety regulations.
