4.5 Refilling with flux powder (Submerged arc welding)
1. Close the flux valve ( 1 ) on the flux hopper.
2. Remove the cyclone on the flux recovery unit, if fitted.
3. Fill with flux powder.
NOTE! The flux powder must be dry.
4. Position the flux tube so that it does not become
kinked.
5. Adjust the height of the flux nozzle above the weld so
that the correct amount of flux is delivered.
Flux coverage should be sufficient so that penetration
of the arc does not occur.
