Note: 1, other specifications of welding wire can refer to the above specifications, according to the need to change. 2. When welding, exceeding the above specifications will affect the performance of the welding wire and the mechanical properties of the deposited metal.

Note

1. In order to ensure the performance of the welding wire, the rust, oil and water on the surface of the workpiece should be cleaned up before welding.

2, when welding, the extension length of the welding wire should be paid special attention to, although too long can improve the welding coating rate, but will worsen the welding process and weld performance. Such as spatter increase, rough shape, etc. Suggestion: When the current is less than 250A, the extension length of the welding wire is about (10~18) mm; When the current is greater than 250A, the extension length of the welding wire is about (20~25) mm.

3. When welding, when the wind speed is greater than or equal to 1.8m/s or high level welding, windproof measures should be adopted, and fans should not be used to blow the welding place directly.

4, the protection gas flow is best controlled between (15~20) L/min.

5. The splash welding slag in the conductive nozzle and guide cylinder should be removed at any time, especially when welding with high current, the conductive nozzle and guide cylinder should be kept clean at any time.

6, after opening the package, the welding wire directly exposed to the air should avoid contact with water, paint, oil, etc., so as not to affect the use of the welding wire.

7, the diameter of the welding wire should be consistent with the specifications of the conductive nozzle, too large to cause poor conduction, affect the formation of the weld, and will make the splash increase.

8, too large or too small welding line energy will seriously affect the overall performance of the weld, should pay special attention to.

9, the above recommendations are for reference only, the user should be based on their own use of the welding process assessment before use, in order to be more in line with their own reality.
