5.5 Changing the feed roller
5.5.1 Single wire
1. Release the knob (3).
2. Release the hand wheel (2).
3. Change the feed roller (1).
The feed rollers are marked with their
respective wire sizes.
5.5.1.1 Knurled rollers for flux-cored wire
• Change both the feed roller (1) and pressure roller (5) for the wire size to be used.
NOTE!
A special stub shaft is required for the pressure roller (ordering no. 0212901101).
• Tighten the pressure screw (4) with moderate pressure to ensure that the flux-cored
wire does not deform.
5.6 Refilling with flux powder
1. Close the flux valve (1) on the flux hopper.
2. Remove the optional cyclone on the flux recovery
unit, if installed.
3. Fill with flux powder.
NOTE!
The flux powder must be dry. Use
preheated flux powder only when the
flux hopper is designed for its use.
4. Position the flux tube without twisting it.
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 to ensure that
arc penetration does not occur.
