A calm heart and a steady hand
Operating instructions:
1, argon arc welding must be operated by the switch.
2. Check whether the equipment and tools are good before work.
3. Check the welding power supply, whether there is a grounding wire in the control system, and add lubricating oil to the transmission part. Rotation must be normal, argon gas, water must be smooth. In case of water leakage, immediate notice should be given for repair.
4. Check whether the welding torch is normal and the ground wire is reliable.
5. Check whether the high-frequency arc initiating system and welding system are normal, whether the wire and cable joints are reliable, and whether the adjusting mechanism and wire feeding mechanism are intact for automatic wire electrode argon arc welding.
6. Choose polarity according to the material of the workpiece and connect the welding circuit. The general material is connected with DC, and the reverse connection method or AC power supply is used for aluminum and aluminum alloy.
7. Check whether the welding groove is qualified. The groove surface shall not have oil pollution and rust, etc., and the oil and rust shall be removed within 200mm on both sides of the weld.
8, for the use of birthgear to check its reliability, welding parts need to be preheated to check the preheating equipment, temperature measuring instrument.
9, argon arc welding control button shall not be far away from the arc, so that in the event of failure can be closed at any time.
10, the use of high frequency arc must often check whether there is leakage.
11, equipment failure should be power outage maintenance, operators shall not repair by themselves.
12, in the vicinity of the arc is not allowed to naked and naked storm other parts, not in the arc near smoking, eating, so as not to ozone, smoke inhalation body.
13. Wear a mask and gloves when grinding thorium tungsten pole, and abide by the operation rules of grinder. Cerium tungsten is best (less radioactive). The grinder must be equipped with a draught device.
14. Operators should wear electrostatic dust mask at any time. Minimize 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 cylinders are not allowed to be smashed, and the vertical placement must be supported and more than 3 meters away from the open flame.
17. When argon arc welding is carried out inside the container, special mask should be worn to reduce the inhalation of harmful smoke. There should be supervision and cooperation outside the container.
18. Thorium-tungsten rods should be stored in lead boxes to avoid injury caused by the radioactive dose exceeding the safety regulation when a large number of thorium-tungsten rods are concentrated together.
