Product in undamaged packaging can be used without re-drying. Re-dried flux must be stored at 300±45°F
(150±25°C) before use.

If the flux packaging has been opened and the flux has been exposed to moist conditions, re-drying is
recommended. The flux should be re-dried at a temperature of 570-660°F (300-350°C ) for a minimum of 2 hours. Re-drying should be made a maximum of three times.

The flux recycling system must be free from moisture and oil. Slag and mill scale must be removed from the recycled flux. At least one part of new flux must be added to three parts of recycled flux.

• Moderate-basicity flux

• High current-carrying capacity

• Excellent slag detachment

• Supplied in moisture-proof packaging

• Provides excellent balance between good weldability and mechanical properties

• Allows the use of high productivity parameters and multiple torch configurations

• Suitable for narrow-groove welding, reduces clean-up time for improved productivity

• Eliminates the need to re-dry unopened product
