AWS A5.18 ER70S-6:

TOKO ER70S-6 is a wire with higher levels of Deoxidizers welding of steels with moderate amounts of scale or rust. (Mn & Si) compared to other carbon steel wires. This wire is suitable for welding of steels with moderate amounts of scale or rust. For Mig welding use Carbon Dioxide or Argon + Co2 or Argon + 2% Oxygen as shielding gases.

ER70S-6, a general purpose welding wire for fabrication of mild steel. Contains more deoxidizers than ER70S-3. The additional deoxidizers also provide better wetting, giving a flatter bead shape and the capability of faster travel speeds. Usually used with 75/25 (argon/CO2) shielding gas or with higher contents of argon, such as 90/10. Can also be used with 100% CO2.

Copper-plated and layer wound. Especially well suited for sheet metal applications or structural plate steels that have moderate amounts of rust oil or mill scale on them Common uses include construction work, farm implement fabrications, general shop applications with poor fit-up or rusty, oily plates, tanks, steel castings or forgings.

Typical applications:

• Repairs on a variety of mild and low alloy steel.

• Small diameter pipe and tubing

• Sheet metal applications

• Root pass pipe welding

Key Features:

1. High levels of manganese and silicon deoxidizers tolerate medium to heavy mill scale surfaces

2. More puddle fluidity,excellent wetting action

3. Storage period: Vacuum packaging less than 1 Year, other packaging less than half year.
