Safety precautions

(1) Ventilation measures for argon arc welding shall be provided with a good ventilation system for the discharge of harmful gases and soot.In addition to the ventilation of the workshop, it is possible to install several axial fan to the outside air in the place where the welding workload is large and the welding machine is concentrated. Besides, local ventilation can be used to remove the harmful gas around the arc, for example, using the bright arc exhaust hood, smoke exhaust welding gun, portable fan and so on.

(2) The radiation dose should as low as possible.When the thorium tungsten and cerium tungsten electrode are processed, the seal type or the wind type grinding wheel should be used. The operator should wear masks, gloves and other personal protective equipment, wash the face after processing. Thorium tungsten and cerium tungsten should be kept in an aluminum box.

(3) The measures taken to prevent and weaken high-frequency electromagnetic fields are as follows:

1) the workpiece is well grounded, the welding gun cable and ground wire shall be shielded with metal braided wire

2) appropriate reduction of frequency;

3) try not to use high-frequency oscillator as an arc device, reduce the time of high frequency electricity work.

(4) in the case of argon arc welding for other personal protective measures, it is advisable to wear non-cotton work clothes (such as acid resistance, oak silk, etc.) due to the strong effect of ozone and ultraviolet rays.If welding in the container without local ventilation, the personal protective measures can be taken by air supply helmet, air mask or respirator can be used.
