Portable Inverter Aluminum AC DC HF Pulse TIG MMA

1. Argon arc welding must be operated by a special person.

2. Check the equipment and tools before work.

3. Check the welding power supply, whether the control system has a grounding wire, and add lubricating oil to the transmission part. The rotation must be normal, and the argon and water sources must be unblocked. In case of water leakage, notify the repairer immediately.

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

5. Check whether the high-frequency arc ignition system and welding system are normal, and whether the wire and cable joints are reliable. For automatic wire argon arc welding, check whether the adjustment mechanism and wire feeding mechanism are intact.

6. Select the polarity according to the material of the workpiece, and connect the welding circuit. For general materials, use DC positive connection, and use reverse connection or AC power supply for aluminum and aluminum alloys.

7. Check whether the welding groove is qualified. There must be no oil, rust, etc. on the surface of the groove. Oil and rust should be removed within 200mm on both sides of the weld.

8. Check the reliability of the tire mold, and check the preheating equipment and temperature measuring instrument for the weldment that needs to be preheated.

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

10. When using high-frequency arc ignition, it is necessary to check frequently for leakage.

11. If the equipment fails, the power should be cut off for maintenance, and the operators are not allowed to repair it by themselves.

12. It is not allowed to be naked or exposed to other parts near the arc, and it is not allowed to smoke or eat near the arc, so as to avoid inhalation of ozone and smoke into the body.

13. Masks and gloves must be worn when grinding thoriated tungsten electrodes, and the operating procedures of the grinder must be followed. It is best to use cerium tungsten electrode (lower radiation dose). The grinder must be equipped with an exhaust device.

14. Operators should wear electrostatic dust masks at all times. Minimize the action time of high-frequency electricity as much as possible during operation. Continuous work shall not exceed 6 hours.

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

16. Argon gas cylinders are not allowed to be smashed. There must be a support for standing upright, and they must be kept away from open flames for more than 3 meters.

17. When performing argon arc welding inside the container, a special mask should be worn to reduce the inhalation of harmful fumes. There should be personnel monitoring and cooperation outside the container.

18. The thoriated tungsten rods should be stored in a lead box to avoid injury due to the radioactive dose exceeding the safety regulations when a large number of thoriated tungsten rods are gathered together.
