DEKA ER70S-6, 3Si1 wire is used for semi-automatic welding of carbon and low-alloy steels in shielding gases: 100% CO2, 80% Ar + 20% CO2. Micropolishing of the wire surface with a special chemical composition increases the conductivity of the wire, reduces the energy required for welding and improves the mechanical characteristics of welds.

The absence of shedding of copper coating in the feed mechanisms, along with a low friction coefficient, reduces downtime of welding equipment related to periodic cleaning of guide channels/hoses and increases the lifetime of the tip.

Chemical composition of ER70S-6, 3Si1, %:
- C ≤0,10
- Si 0,60 – 0,85
- Mn 1,40 – 1,70
- P ≤ 0,030
- S ≤ 0,025
- Ni ≤ 0,25
- Cr ≤ 0,20

The wire is manufactured in St. Petersburg, Russia, and offers several advantages over alternatives. It prevents the shedding of the copper coating in feed mechanisms, reducing the need for frequent cleaning and extending equipment life. Additionally, it avoids short circuits during high current operations and is cost-effective compared to copper-clad wires.

The chemical composition of DEKA ER70S-6, 3Si1 includes carbon (≤0.10%), silicon (0.60–0.85%), manganese (1.40–1.70%), phosphorus (≤0.030%), sulfur (≤0.025%), nickel (≤0.25%), and chromium (≤0.20%). This composition ensures durability and reliable performance.

Available in diameters of 0.8 mm, 1.0 mm, 1.2 mm, and 1.6 mm, the wire supports a broad range of welding applications and operates effectively across various temperatures. It is a versatile choice for users requiring high-quality welding wire.
