Weld Mode-Used for most welding applications. In this mode the shade function is turned on. When it
optically senses a welding arc, please select a suitable shade level,delay time and sensitivity as required.
5.2 Selecting Delay Time
The Delay Time knob will vary from dark to light time,it can be set at MAX (1.0 second) or MIN
(0.1second) by using the in nitely dial knob.(See Fig.6)
MA X 1.0 second-Longer delay is for most welding applications, specially for high amperage (current)
applications.
MIN (0.1 s ec ond)-Shorter delay is for Spot welding applications
Longer delay can also be used for TIG Welding in order to prevent the lter opening when the light path
to the sensors is temporarily obstructed by a hand, torch, etc.

5.3 Selecting Sensitivity
The sensitivity can be set at "HI"(High) or "LO"(Low) by using the in nitely dial knob. (See Fig.7)
As a simple rule for optimum performance, it is recommended to set sensitivity at the High at the
beginning and then gradually reduce it, until the lter reacts only to the welding light ashes and
without annoying spurious triggering due to ambient light conditions (direct sun, intensive arti cial
light, neighboring welder 's arcs etc.).
"HI" (High)- Most for welding applications but specially for low welding current work.
"LO" (L ow)- Only in some speci c surrounding lighting conditions in order to avoid unwanted
triggering.
