(1) ensure the working environment with good ventilation

Because CO2 is CO2 gas shielded arc Welding Electrodes as a protective gas, at high temperatures have a lot of CO2 gas will decompose to produce CO and produce large amounts of smoke. CO easily and human blood protein binding, causing the body hypoxia. When the air in only a small amount of CO, will make people feel unwell, headache, and when the CO concentration exceeds a certain range will cause people difficulty in breathing, coma, severe and even cause death. If the gas concentration of CO2 in the air over a certain range, can also cause the reaction. This requires that welding work environment should have good ventilation, can not ventilate the local space welding should be worn to supply fresh oxygen mask and oxygen bottle.

(2) paid to the choice of capacity appropriate power supply, power switch, fuses and auxiliary equipment to meet the high load rate has continued to work requirements.

(3) adopt the necessary measures to prevent electric shock protection devices with good isolation and automatic power-off devices; welding equipment must be ground or zero protection and regular inspection and maintenance.

(4) with the necessary fire safety measures. As the metal spatter fire is more dangerous than other welding methods, demanding welding jobs around to take in the reliable isolation, shielding, or measures to prevent flying sparks; welders to maintain a good working protective equipment to prevent the body burns.

(5) The CO2 gas shielded arc welding Submerged arc stronger than normal, ultraviolet radiation is more intense, darker the filter should be used.

(6) electric heater using CO2 gas, the voltage should be less than 36V, shell have to be grounded.

(7) The high-pressure liquid CO2 is dressed in a cylinder, to prevent direct heat CO2 cylinders, gas cylinders can not be near sources of heat, but also to prevent excessive vibration.

(8) to strengthen personal protection. Woman wearing a mask, gloves, put on work clothes, work shoes.

(9) when the conductive wire into the mouth, the fingers on the gun does not allow the end to check the wire sent the case; do not allow the gun to protect your ear to test the gas flow.

(10) using the torch water cooling system should be insulated to prevent the destruction of electric shock.

(11) after the Mig Welding Rod work, turn off the power and gas sources, and carefully check around the workplace and protection facilities, only after confirming that no fire hazard to leave.
