1. Applications:
NB-7018 welding electrode is the high iron high-quality product that possesses high welding efficiency due to the low amount of hydrogen. It excels in welding steels with high tensile strength.
2. Usage instructions:
NB-7018 product is suitable for welding structural steel with tensile strength higher than 560N/mm2 such as building ships, bridges, pressure pipes, heavy machinery, pressure tanks, mining tools, etc...
3. Warning:
- Fumes and gases can be hazardous to your health.
- Arc rays can injure eyes and burn skin.
- Electrick shock can be lethal.
- Wear proper eyes, ears and body protection.
- Do not touch live electrical parts.
