5.4.1.1
Knurled rollers for flux-cored wire
• Change the feed roller (

) and pressure roller (
5
) as a pair for the wire size to be used.
NOTE!
A special stub shaft is required for the pressure roller (ordering no. 0212 901 101).
• Tighten the pressure screw (

wire does not deform.

Close the flux valve (

) on the flux hopper.
2.
Remove the optional cyclone on the flux recovery
unit, if fitted.
3.
Fill with flux powder.
NOTE!
The flux powder must be dry. Use
preheated flux powder only when the
flux hopper is designed for that.
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 so that
penetration of the arc does not occur.
