SPECIAL INSTRUCTIONS:

  • Dry the flux at 3000C –3500C for 1 hour before use.
  • Avoid using high current to prevent harming of corrosion- resistibility in heat-affected zone. Heat-input in welding should be kept as low as possible.
  • Welding in groove should be done in 2 passes to ease slag removal
