7. INSTRUCTIONS FOR USE
- Fully preparing the elements of labor safety before welding. Welding power source is stable.
- When the welding rod is moist, welding is vulnerable to smoke, splashed and unstable, weld is clarified, need to dry at 100oC – 150oC in 40 – 60 minutes before use.
- Removing all traces of oil, dust, dirt on the surface of the weld.
- Making sure the weld gap, bevelled edge of welding materials as prescribed to achieve strong weld.
- Selecting the welding line according to the instructions to obtain the deep weld, high working ability.
