As an important part of the development of modern industrial machinery, more and more people use the welding machine. It has many advantages, such as no welding wire, simple operation, high productivity, small heat affected zone, etc. there are also many matters needing attention in the use process. Today, the editor in chief of tian will introduce the matters needing attention in the use of the welding machine~
1. After welding, the gate shall be cut off and the power shall be cut off, the ground wire shall be separated from the connecting wire, and the spark of molten slag shall be extinguished before leaving the site.
2. It is strictly prohibited to replace the ground wire with metal objects such as metal pipe, metal foot, track and structural reinforcement.
3. When loading and unloading acetylene gas cylinders or petroleum cylinders, pay attention to handle them with care, and do not throw, touch, slide, roll and other violent vibrations.
4. The surface temperature of acetylene cylinder shall not exceed 40 ℃.
5. When using oxygen cylinders and electric welding in the same place, pay attention to the insulation at the bottom of the cylinder to prevent the cylinder from being charged.
6. When the electric welding machine is used outdoors, a waterproof and moisture-proof mechanical shed shall be set and equipped with fire-fighting equipment.
7. Electric welding tongs cannot be used after being immersed in water and cooled after overheating.
8. The length of the power line measured by the welder at one time shall not exceed 5m.
9. The length of secondary measuring line and ground wire of welding machine shall not exceed 30m.
10. The handle cable of the welding machine shall adopt the flexible cable of multi strand thin copper wire with rubber sleeve.
11. The no-load voltage of AC welding machine shall not exceed 80V.
12. The distance between oxygen cylinder and acetylene cylinder shall not be less than 5m.
13. When carbon dioxide gas shielded welding is carried out, the carbon dioxide gas shall be preheated for 15 minutes before operation.
These precautions can be better used only according to the correct operation method and correct use process.
