ER70S-6 Spools Carbon Steel Welding Wire Blue Demon

ER70S-6 is a mild steel welding wire that contains
higher levels of manganese and silicon than other
standard grades of MIG wire to produce high quality
welds when used on dirty, oily, or rusty steel. The high
silicon content increases the fluidity of the weld pool,
thus creating a smoother bead appearance and resulting
in minimal post-weld grinding. This wire is engineered
to provide porosity-free, x-ray quality welds at
the highest tensile strength (as welded) of all the plain
carbon steel wires. This product requires a shielding
gas: CO2 and/or CO2 mix.

Typical Applications
• General shop applications with poor fit-up
or rusty, oily plates
• Steel castings or forging salvage
• Home projects • Tanks
• Sheet metal • Construction work
