E70C-6M metal-cored welding wire combines
the efficiencies of solid (GMAW) wires with the
high productivity rates of flux-cored (FCAW)
wires - low fume generation rates, high
efficiencies, no slag to clean or remove -
with all the advantages cored wires have
over solid wires - no "cold lap" or lack of
sidewall fusion, pure spray achievement with
75-80% argon/balance carbon dioxide, faster
travel speeds for a given fillet size. E70C-6M
is well suited to applications where higher
manganese and silicon levels are essential,
such as in the presence of heavy mill scale or
mild contaminants, or when improved wetting
of the weld bead is desired. This product
excels in general purpose welding, but is
equally superior in higher demand situations
as in heavier sheet metal fabrication, structural
work, pipe welding and welding of hot
water heaters.
