MetalshieldMC-715

Mild Steel Metal-Cored Wire (AWS E70C-6M H8)

Metalshield MC-715 is designed for virtually slag free deposits in single or multiple pass welding applications. Its design achieves robust low temperature impacts and can be used in semiautomatic and automatic applications. Excellent for welding over scale or surface contaminants.

Advantage Lincoln

Welding Positions

Smooth, spray-type arc transfer and low spatter level.

 

 

 

 

 

High deposition efficiency.

 

 

 

 

 

Good resistance to porosity on mill scale.

Typical Applications

Mining equipment

Heavy equipment

Offshore

General structural fabrication

Shielding Gas

75-95% Argon / Balance CO2

Flow Rate: 30-45 CFH

Higher argon percentage will lower the amount of generated welding fume. A 15-25% CO2 range may be used for improved arc characteristics when welding in the short circuiting mode.
