STAYER WELDING AS-XL Manual De Instrucciones página 14

The level of protection against radiations IR/UV is
permanently set at 13 degrees.
The filter includes 2 superficial removable transparent high
weight molecular polymer protectors which are resistant
to particle sticking, and excessive use.
The unit is power via integrated solar cells in a way that
the user does not have to change batteries or turn on nor
off the unit.

4. USER INSTUCTIONS
4.1. Adjusting the mask to the user.
Adjustments may vary do to different sizes of users head.
To correctly adjust the equipment to individual users,
follow the proceeding instructions.
1. Adjust the height of the head: Adjust the upper band of
the harness (8), adjust the length of the band so that
it sits on the head in a way that the eyes are at the
height of the filter with the mask perpendicular to the
horizon and the harness is parallel to the horizon.
2. Adjustment of the perimeter to the head: Adjust the
adjustment knob (10) by pushing and turning until the
harness sits comfortably without too much slack or too
much pressure.
3. Adjust the angle of vision: Loosen screws (13), Lift and
turn the work angle adjustment deck (9) in a way that
the upper part of the mask is in its working position
(stopper of the harness resting in the stopper of the
deck (9) ) an angle of 10º to 15º towards the face of
the user.
4.2. Adjusting protection angle
The equipment has a three-position range selector:
1. Shadow range DIN 5-9.
2. Shadow range DIN 9-13.
3. Shadowless grinding.
ENGLISH
14
Work generally within range 9-13 except for low light
intensity work such as low intensity TIG or soft flame
welding.
Grinding mode: the filter does not darken in this mode,
avoiding loss of vision when used as protection against
grinding spattering with sparks.
Adjust knob (4) using the following table based in UNE EN
379:2009-07.
These tables are valid for mid class work conditions where
the distance between the operators eyes and the base of
the molten metal is approximately 50 cm and the middle
brightness is around 100 lx.
The use of a degree of protection higher does
not necessarily proportion more protection
and obligates the user to close in on the
radiant source and breath harmful fumes.
It's possible to use filters with one more
degree of protection when working in open
air where there is a strong natural illumination.
4.3. Adjusting sensibility
This regulation, labeled "SENSIVITY" (nº 15) calibrates
the minimum light intensity needed for darkening the filter.
Adjustment is continuous form minimum to maximum
but three standard position (min, medium and max) are
explained.
1. Min. (LO) Used when is used close to another welders
arcs. The purpose is to avoid not desired darkening
of the filter when other welders have established their
welding arc. Complementary to this use case is the
situation of high amperage welding.
2. Medium. This is the standard and initially recommended
position for medium amperages and / or sunlight
conditions.
3. Max. (HI) For use in covered and alone welding with
no interference with another welder's arcs.
Complementary is the situation of low amperage
welding in no sunlight presence. Staring to sunlight
can fire darkening when filter is at maximum sensibility.
It is recommended to start adjustment at mid position
adjusting until the adequate adjustment is obtained.
4.4 Adjusting wait time
This regulation is named "DELAY" (nº 16) and sets the time
elapsed between the end of welding arc and the return to
clear state of the welding filter. Two limit use cases are
described, Min and Max positions. Rank 0.2-1 second.
1. Max. (1 second) For using at high amperage welding
with very bright welding pool. In this case is desirable
a slight cool of pool before enable eye to see.
