The motor, electric appliance, air compressor, etc. on the welding equipment should be carried out according to the relevant regulations, and have a complete protective shell. There should be a protective cover at the one or two junction.
The electric welding machine used in the field should be equipped with rain proof, moistureproof, sunscreen and fire protection equipment.
In welding, the welding and matching personnel must take safety measures to prevent accidents such as electric shock, high altitude falling, gas poisoning and fire.
It is strictly prohibited to weld and cut the pressure pipes, vessels equipped with inflammable and explosive materials and force members in operation.
When welding copper, aluminum, zinc, tin, lead and other non-ferrous metals, it must be carried out in a well ventilated place, and the welder should wear a respirator or a respirator.
The following measures must be taken when welding the container. There must be inlet and outlet and ventilation equipment on the container. The lighting voltage in the container should not exceed 12V. When welding, there must be someone on-site monitoring, and it is forbidden to weld in the painted paint or plastic container.
When welding preheated weldments, the radiant heat from the baffle isolating weldment should be set.
When welding or cutting at high altitude, a safety belt must be hung. Fireproof measures and special guardianship should be taken around and below the weldment.
When the wire is passed through the road, it must be high or buried inside the protective tube, such as through the track, it must pass through the track.
The ground and handlebars shall not be attached to inflammable, explosive and heat source articles. The grounding wires must not be connected to pipelines, machine tools and building metal frames or tracks, and the grounding resistance is not greater than 4 ohms.
There is no surface electric welding on rainy days. When working in a damp area, the operator should stand in the place of insulation and wear insulating shoes.
When used for a long time, the electric welding machine must be checked that the insulation resistance should not be less than 0.5M Omega. The connection part must not have corrosion and damp phenomenon.
With the hand line welding tongs should be firmly connected, no arm clamping pliers.
When cleaning slag, the face should avoid the clear weld.
During the load operation, the welder should often check the temperature rise of the welding machine, such as over a class a 60 C, B level 80 C, must stop running and cooling.
In the 10m range of the welding site, inflammable materials such as oxygen gas cylinder, acetylene generator and wood shall not be stacked.
After the operation, cleaning up the site, the fire extinction, cut off the power supply, the lock gates box, eliminating solder heat, can leave.
