Instruction
ER70S-6 welding wire is a manganese-silicon alloyed solid wire for GMAW of unalloyed steels, such as general structural, pressure vessel, ship building and for fine-grained carbon-manganese steels for the same purpose with a minimum yield strength of max 420 MPa. The electrode can be welded with Ar/20CO2 or with pure CO2 as the shielding gas. The AristoRod wires are suitable for operating at high currents with maintained disturbance free wire feeding giving a stable arc with a low amount of spatter.
Application
ER70S-6 welding wire is used to weld ship building steel and equivalent mild steel or 550Mpa grade mild alloy steel, such as vehicles, bridge-engineering, machine-engineering, steel structures, ship manufacture and trade container making for semi-auto or automatic gas shielded welding.

Notes:
1.Wire shall be stocked in dry.open the packs just when welding to avoid the wire rust.
2.Before welding please clean out the oil,rust,water etc from the work parts
