4.1 REPLACEMENT OF WELDING FILTER LENS,
PROTECTION PLATE AND SAFETY PLATE
Replacement of welding filter lens and front-mounted protection
-lift up hatch of welding filter lens.
-(1) Release filter retaining spring with finger from hatch slot.
-(2) Remove welding filter lens (and eventual protection plate).

-(3)Front-mounted protection plate is removed by drawing it
-Replacement of the inner safety plate, attached to the welding
-Lift up hatch of welding filter lens.
-(4)Press safety plate out of its place.
Mount new safety plate by bending it so that its ends slide
between the cogging in the helmet. Release the plate at its place
by unbending it. Make sure that the plate is fully in the slot.4.2 USE OF VIEWING POSITION OF WELDING HELMET
The welding filter lens hatch has an intermediate position to
make welding start or e.g. short tack welds easier.
NOTE! Through the slit you can check the start point before
starting but you should adjust the welding helmet before arc
ignition such a way that the igniting arc can be seen through the
welding filter lens.
We recommend that the viewing position is used only temporarily
and with low welding currents. At higher currents the
radiation coming through the hatch openings may burn the skin
and reduce vision through the welding filter lens.
Never use the viewing position with auto darkening welding
filter. Diffused light hinders normal function of the filter.
Never watch the arc through the slit!
Height adjustment of band:
Adjust the headband height so that the band part circling the
head positioned relatively low, in which case the welding helmet
stays rigidly positioned on the head.
counterpart (D).Adjust the upper part of band to the desired
length by moving plastic strips in regard to each other. Press
the plastic strips against each other so that the plastic pins are
placed into holes of counterpart.
Tightening adjustment of band:
Adjust the band tightness suitable for your head by rotating
the adjusting wheel (G).
Adjustment of welding helmet angle:
Adjust the welding helmet angle in regard to your face so that
the lower edge of welding helmet is positioned near your chest
in the welding situation, in which case the welding helmet gives
the best protection. Bend the adjustment plate (A) inwards so
much that the plastic pin(B) of the welding helmet comes out
of the hole of the adjustment plate. Turn the adjustment plate
and release the plate so that the screw is placed to the desired
hole of the adjustment plate.Tightening adjustment of welding helmet:
Adjust the tightness of welding helmet in regard to band by
rotating the screw (E) and (F), adjust the tightness of helmet so
that the high raised helmet stays up, but goes down when you
nod your head. If the helmet strikes against your chest when
failing, the adjustment is too loose or the helmet angle has been
adjusted too near your face from the adjustment plate (A)
