MAG shielded welding wire

MAG welding wire is a type of silicon manganese alloy welding wire in two types with copper coating and without copper coating (ER70S-6, G3Si1) which is used for welding metal arcs with GMAW shielding gas.

MAG welding wire is a kind of silicon magnesium alloy in two types with and without copper coating that being used in welding metal arc with GMAW protective gas.

Welding current: +DC

Shielding gas: Pure CO2 or mix (80% Ar + 20% CO2)

Advantages:

• Great start
• Wireless feeding at high speeds
• Long feeding intervals
• Very stable arc at high current intensities
• Low vapor emission
• Reduce erosion on the wire contact surface inside the nozzle
• Proper protection of the wire against corrosion

Applications:

• Construction steels
• Fine-grained steels
• Pipe steel
• Boiler steels and pressure vessels
• High temperature steels
• Shipbuilding steels
• Casting steels
