Filling with flux (applies to A6 TFD1 och A6 TFD2)
1. Close the flux valve on the flux container.
2. Remove the separator from the flux recovery unit, if fitted. Fill with flux.
NOTE! The flux must be dry. Whenever possible avoid using agglomerated flux
outdoors or in a damp environment.
3. Adjust the height of the flux nozzle above the weld, to give the correct coverage
of flux. The flux cover should be sufficient to prevent the arc burning through.

the production work piece.
NOTE! Never make a test weld on a production work piece.
