PRIMACORE ® MW-71
PRIMACORE® MW-71 is a basic-rutile, flux-cored welding wire designed for all-position welding of mild steel in applications requiring moderate levels
of strength and good impact toughness. PRIMACORE® MW-71 provides great arc stability and smooth bead appearance, even on out-of-position welds.
It should be used with 75-80% Argon/Balance CO2 gas.
