Certificates:
CE
Application
- Shipbuilding
- Pressure Vessel
- Energy Industry
- Heavy Machinery
DETAILS
Mild steel rutile stick electrode designed for use with small AC welders with low OCV
Features
- Copper-free surface for reduced copper fumes and a cleaner working environment
- Extended contact tip life and significantly reduced tip clogging
- Exceptional wire feedability for stable high-speed and long-distance feeding
- Smooth arc performance with extremely low spatter
- Excellent arc re-striking and high resistance to surface flash rust
Typical Applications
- Robotic and automated welding lines
- Automotive and heavy machinery manufacturing
- Structural steel and bridge construction
- Pressure vessel and pipe fabrication
- High-efficiency carbon steel welding projects
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.
