VIKING PAPR 3350 WELDING HELMET
Cartridge oPeration/Features
Variable Shade Control
The shade can be adjusted from shade 5 to 8 and 9 to 13 based
upon welding process or application (refer to lens shade selection
chart on page 20). Shade is adjusted by setting the shade range
switch to the proper range, then use the shade dual scale dial to
set the desired shade. The shade range switch and dual scale dial
are located on the Auto-Darkening Lens as shown in figure 11.
Test
Press and hold test to preview shade selection before welding.

Sensitivity
Shade Range Switch
Adjust the light sensitivity by turning the SENSITIVITY knob to the
left or right as shown in the figure below. Turning the knob all the
way to the left is the HI setting. When helmet is used in the
presence of excess ambient light or with another welding machine
close by, improved helmet performance can be obtained with a
lower setting by turning the knob to the right to reduce the
sensitivity. Grind mode can be selected by rotating the sensitivity
knob all the way to the right until an audible click is heard.
Grind mode is intended for grinding only not for
welding.
Delay Knob
This control is designed to protect the welder's eyes from the
strong residual rays after welding. Changing the DELAY knob will
vary the dark to light time between 0.1 second (S) to 1.0 second
(L).
The L setting is recommended for high amperage applications
where the weld puddle is still very bright after the welding arc has
ceased and for situations where the Lens may be temporarily
blocked from seeing the welding arc.
Shade Dual Scale Dial
Power
This Auto-Darkening Lens is powered by a replaceable battery and
solar power. The battery is located at the bottom corner of the
Auto-Darkening Lens. Replace battery when LOW BATTERY light
is lit. See the specification chart on page 17 for type of battery
required. See Auto-Darkening Lens shown in figure 11 for battery
proper charge orientation for installing into Auto-Darkening Lens.
Battery compartment door release slides down and rotates open
as shown.
