MC-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
• Smooth, spray-type arc transfer and low spatter level.
• High deposition efficiency.
• Good resistance to porosity on mill scale.
• Excellent "fast follow" characteristics.
• Robust low temperature impact properties.
• Manufactured under a quality system certified to ISO 9001
requirements.
Welding Positions
Typical Applications
• Mining equipment
• Heavy equipment
• Offshore
• General structural fabrication
Shielding Gas
75-95% Argon / Balance CO
2
Flow Rate: 30-45 CFH
Higher argon percentage will lower the amount of generated welding
fume. A 15-25% CO
2
range may be used for improved arc
characteristics when welding in the short circuiting mode.
