DETAILS
Mild steel rutile stick electrode designed for use with small AC welders with low OCV
Features
- High level of deoxidizers for welding on light rust or mill scale
- Smooth arc, low spatter, and clean weld bead appearance
- Excellent wire feedability and stable arc transfer
- High deposition efficiency and deep penetration
- Compatible with CO₂ or Ar/CO₂ shielding gas
Typical Applications
- General carbon steel fabrication
- Automotive manufacturing and body repair
- Structural steel and frame construction
- Pressure vessel and pipe welding
- Sheet metal fabrication
Welding Positions
- PA / PB / PC / PD / PE / PF / PG
WARNING
- Rust, oil, moisture, and other contaminants must be removed from the weld zone before welding.
- The mechanical properties of all-weld metal are determined by heat input; lower heat input is generally preferred to higher heat input.
