WELDING FUNCTIONS
Selecting the Operating Mode: Slide knob
to select between GRINDING or WELDING
(See Fig. 4)
Grinding Mode: This function is used for metal
grinding applications, not welding. In this mode
the autodarkening shade function is turned off.
The shade is fixed in the light state that allows
a clear view to grind. Before restarting welding,
set knob back to WELDING.
Welding Mode: This function is used for most
welding applications. In this mode, the shade
function is turned on. Select the correct shade
level, delay time and sensitivity as required
and before commencing welding.
Selecting Shade Level: Select the prescribed
shade level you require according to the
welding process you will use [see "SHADE
SELECTION CHART"]. For the WHAM30 model,
slide the knob to select between shades "5-8"
or "9-13" (Fig 4.) Use SHADE dial to select an
exact shade level (Fig 4.)
Selecting Delay Time: The Delay dial (Fig 4.
right) will vary the time to switch between
dark & light. It can be set between "MAX" (1.0
second) or "MIN" (0.1 second).
MAX (1.0 second): Longer delay is for most
welding applications, specially for high
amperage (current) applications. Longer delay
can also be used for TIG Welding in order to
prevent the filter opening when the light path
to the sensors is temporarily obstructed by a
hand, torch, etc.
