OPERATING INSTRUCTIONS
ASSEMBLY
Assemble the mask as shown in fig.1 opposite
POWER SUPPLY
Power supply is provided by solar cells controlled with micro circuitry which automatically
turns the helmet on and off without having to touch a switch or button.
DARKNESS SELECTION
When you strike an arc, the observation window darkens immediately and at this moment
the operator needs to adjust the darkness shade by turning the knob to the optimum shade
for the current work being undertaken. (see page 6.)
Fitting Fitting
All heads are different shapes and sizes, therefore it is important to adjust the headband to
fit and set at the correct observation angle. To do this, firstly adjust the skull strap (8) to
the correct position to locate the sweat band (7) comfortably on your forehead. Secondly,
adjust the tightness by depressing and turning the tightness adjuster (10) to suit - do not
over tighten as this will cause headaches. Finally, loosen the locking nuts (13) to enable
you to pivot the mask to the desired viewing angle on the positioning plate (9) then tighten
the locking nuts again.
CHANGING THE PROTECTION PLATES
This welding helmet must always be installed with an inner and outer protection plate
before welding. These may need replacing at some point.
To replace the lens/protection plates:
Firstly, remove the fixing screws (5) and the frame (1).
To remove the inner protection plate (2), lever out with a finger nail from the recess in the
centre above the plate and to replace, locate one side behind the corner tabs then flex in
the middle in order to locate behind the tabs on the other side.
To remove the outer protection plate (6), first you must remove the filter lens assembly (3)
as above, then from the inside press the outer protection plate in the middle to remove. To
replace, insert the new one, locate one side behind the side tabs on the outside then flex in
the middle in order to locate behind the tabs on the other side.
CLEANING
This welding helmet should be cleaned regularly with a fine soft brush to remove dust and
particles. If absolutely necessary, you may clean with soapy water after removing the filter
lens assembly completely.
To do this, pull the shade adjusting knob off it’s spline, remove the 10mm locking nut then
remove the lens from between protection plates as described above. Do not immerse in
water.
