• ADJUSTING VIEW ANGLE POSITION
Please see Fig. 2
• SELECTING SHADE LEVEL
Select the shade level you require according to the welding process
you will use by referring to the "Shade Guide Table" below for
settings. Turn the shade control knob on the side of the helmet to
the shade number required.
• SELECTING THE GRIND OPTION
When the shade knob is turned to the "grind" position, the shade
function is turned off allowing a clear view to grind a weld with the
helmet providing face protection. Ensure that the shade function is
turned back on before welding again (see Fig. 3).
• SENSITIVITY
The sensitivity can be set to "H" (high) or "L" (low) by using the
infinitely dial knob on the back of the shade cartridge. The "Mid-
High" setting is the normal setting for everyday use. The maximum
sensitivity level is appropriate for low welding current work, TIG, or
special applications. Where the operation of the helmet is disturbed
by excess ambient light, or another welding machine close by,
use the "low" setting (see Fig. 4a). As a simple rule for optimum
performance, it is recommended to set sensitivity to the maximum
at the beginning and then gradually reduce it, until the filter reacts
only to the welding light flash and displays no annoying spurious
triggering due to ambient light conditions (direct sun, intensive
artificial light, neighbouring welder's arcs, etc.).
• SELECTING DELAY TIME
When welding ceases, the viewing window automatically changes
from dark back to light but with a pre-set delay to compensate for
any bright afterglow on the workpiece. The delay time/response
can be set to "S" (short: 0.1 sec.) or "L" (long: 1.0 sec.). Use the
infinitely dial knob on the back of the shade cartridge as needed
(see Fig. 4b). It is recommended to use a shorter delay with spot
welding applications and a longer delay with applications using
higher currents. Longer delays can also be used for low current TIG
welding in order to avoid the filter opening when the light path to the
sensors is temporarily obstructed by a hand, torch, etc.
Definition of the abbreviations found on the filter
"L" on the Sensitivity switch means Low
