1, welding man-machine material ring, operation skills first.

2, the combination of hand and brain is the most important, and should not be impetuous.

3. Stiffness of the right hand is a taboo, and both internal rotation and external rotation are time-varying.

4, vertical and horizontal three directions, keep in mind the three-point welding.

5. According to the specification, the components before welding should be made of high-quality and dry covered electrode.

6, skilled ignition arc, scratch impact optional.

7. After the arc combustion, the heart is in no hurry, and preheating the parent metal is quite critical.

8. Wait until the temperature rises, and then implement short arc welding.

9, molten pool molten hole to see clearly, not blindly.

10, stop the arc when the temperature is high, and continue welding when the temperature is low.

Safety precautions for welders:

1, welders must undergo professional training and pass the examination before they can take up their posts. Non-welders are forbidden to engage in welding operations.

2. Wear safety protection articles such as welding overalls, insulating shoes, welding gloves and protective masks during operation. Fasten your seat belt when working at height.

3. Flammable and explosive articles shall not be piled up within10m of the welding operation site.

4, rain, snow, wind level 6 and above windy weather shall not engage in outdoor operations. After rain and snow, water and snow should be removed before operation.

5. Before operation, check the welding machine and tools, such as the insulation of welding tongs and welding cables, the protective grounding of the welding machine shell and various connection points of the welding machine. Before operation.

6, it is strictly prohibited in the inflammable and explosive gas diffusion zone, pressure pipes and containers filled with inflammable and explosive articles for welding or cutting on the mechanical parts of the running heart.

7. When the welding site is wet or the clothes of the welder are wet after sweating, it is forbidden to lean on the charged steel plate or workpiece. Welders should work on dry insulating boards or rubber mats, and personnel should wear insulating shoes or stand on insulating boards.

8. When welding, it is forbidden to suspend the temporary grounding wire head, which must be fixed, compacted and wrapped with tape.

9. When troubleshooting, replace the welder connector, connect the secondary circuit, carry the welder and replace the safety device. When you finish or leave the site temporarily, please cut off the power.
