APPLICATION: It is applicable for the welding of carbon steel and low-alloy steel structure used for ship, bridge, architecture, vehicle and machine building.

Caution:
1. Direct current electrode positive(DCEP)welding(the welding wire is connected to positive pole)
2. Use CO2 as shielding gas and the degree of purity is required to be above 99.8%. The flow rate is 20-25L/min.
3. As for multiple pass welding, maintain the interlayer temperature to be approximately 150-200
4. In order to avoid the air hole, oil dirt and corrosion surface of base metal should be cleaned off before the welding.
5. Preservation of welding wire: Measures of damp proofing have been adopted before it is put into use, Use it as soon as possible after unpacking, Never put the remaining wire in the air for long time without coverage.
6. Because the welding wire is softer than the solid one, do not make the pressure roller of wire feeder too tight.
