The operating procedures are as follows:

1, argon arc welding must be operated by a special switch.
2. Check whether the equipment and tools are good before work.
3. Check the welding power supply, whether the control system has a grounding line, and add lubricating oil to the transmission part. For normal rotation, argon and water must be unblocked. If there is water leakage, you should immediately notify the repair.
4. Check whether the welding torch is normal and the ground wire is reliable.
5, check the high frequency arc starting system, welding system is normal, wire, cable joint is reliable, for automatic wire argon arc welding, but also check the adjustment mechanism, wire feeding mechanism is intact.

6, according to the material of the workpiece to choose polarity, connect the welding circuit, the general material with DC direct 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 to remove oil and rust within 200mm.
8, for the use of fetal to check its reliability, the welding parts need to preheat but also check the preheating equipment, temperature measuring instrument.
9, argon arc welding control button shall not be far 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 outage maintenance, operators must 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, when grinding thorium tungsten electrode must wear a mask, gloves, and comply with the grinder operating rules. It is best to choose cerium tungsten electrode (less radiation). The grinder must be equipped with an air extraction device.
14, the operator should always wear electrostatic dust mask. Minimize the high frequency electrical action time during operation. The 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, the argon cylinder is not allowed to crash, standing must have 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 fumes. There should be a person outside the container to monitor and cooperate.
18, thorium tungsten rod should be stored in the lead box, to avoid due to a large number of thorium tungsten rod concentrated together, the radioactive dose exceeds the safety regulations and cause injury.
