Shieding Gas	80%Ar + 20%CO2

 

Characteristics：

(1) This product is the 800MPa grade high strength steel wire, it has very good mechanical properties. 

(2) With the mixed shielding gas,this wire can be used to welding the important corresponding level structures.

 

Precautions：

1. Pay attention to the gas purity and mixture ratio. 

2. Keep the gas flow rate between 15 ~ 25 L / Min. 

3. The extension length keep between 15 to 20mm  

4. Clear the oil, rust, moisture, dust and other debris of the welded parts. 

5. Keep the welding hood clean and unobstructed.
