Classification
| AWS class | ER 70S-6 |
|---|---|
| EN ISO class | G 42 4 C/M G3Si1 WIG: EN |
| Other standards | ISO 20172: Gruppe 1.1 · TÜV Kennblatt 1000: Gruppe 1 |
Purpose
- General-purpose solid MIG wire and TIG rod for carbon and low-alloy steel (AWS ER 70S-6, EN ISO G 42 4 C/M G3Si1) — the most widely used reference in the Dratec range.
Why it works
Higher silicon content than FERVEO STL SG1 improves weld-pool deoxidation in MAG welding with CO2 or mixed gas, in all positions — the reference composition for general work outside the galvanized-sheet niche.
Fields of application
- General carbon and low-alloy steel, MAG welding in all positions with CO2 or mixed gas.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.

Advantages
- Available as both MIG wire and TIG rod under the same reference.
- Good weld-pool deoxidation with CO2 or mixed gas, in all positions.
Limitations
- For higher Mn-Si content in the same MIG process, see FERVEO STL SG3.
