What should I pay attention to when replacing gas cylinders during welding?

Replacing gas cylinders during welding is a common operation, but it is also a risky job. Here are a few things to pay attention to when replacing gas cylinders:

Safety check: Before replacing gas cylinders, you must ensure that all equipment is in a safe state. This includes checking whether the welding gun or gas cutting torch head has cracks or wear, confirming that the electric welding and gas cutting equipment is working properly, and checking whether the leaks and gas pressures (such as O2, C2H2) on the equipment are within the safe range.

Release pressure: When replacing gas cylinders, you first need to release the existing gas pressure before removing the gas cylinder. This is to avoid accidents caused by excessive pressure.

Correct operation: When replacing gas cylinders, you need to get close to the equipment and use appropriate protective equipment to prevent gas injection from causing danger. At the same time, pay attention to the installation direction of the gas cylinder and ensure that the gas cylinder interface is correctly connected to the solenoid valve.

Environmental safety: When replacing gas cylinders, you need to ensure the safety of the operating environment. This includes avoiding fire sources, maintaining good ventilation, and avoiding direct sunlight.

Personal protection: When replacing gas cylinders, operators must wear appropriate personal protective equipment, such as goggles, masks, mouthpieces, earplugs, insulated shoes and gloves, etc., to prevent dangerous substances such as high temperature, high voltage, and radioactive substances from causing harm to the body.

Emergency treatment: During the replacement of gas cylinders, if leakage or other emergencies occur, appropriate emergency measures should be taken immediately, such as cutting off the power supply and gas source, opening the indoor exhaust facilities and opening doors and windows for heat dissipation.

In summary, when replacing gas cylinders during welding, attention should be paid to safety inspections, pressure release, correct operation, environmental safety, personal protection and emergency treatment. Only by strictly following these precautions can the process of replacing gas cylinders be ensured to be safe and smooth.
