(1) This product is the 700MPa 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 low alloy structures, and widely used in the welding of scraper chainand hydraulic supports in mining machinery.
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.
