Metalshield
Mild Steel Metal-Cored Wire
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

• 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.
Typical Applications
• Mining equipment
• Heavy equipment
• Offshore
• General structural fabrication
