5.2 Sensitivity and Delay Adjustment
Section 5 - Variable Shade, Sensitivity, and Delay Adjustment
Lens Delay Adjustment (#2)
The lens delay adjustment is used to
control how fast the lens switches
back to the light state after welding.
The delay is very helpful in higher
amperage applications where the
molten puddle remains bright
momentarily after welding. Adjusts
from Minimum 0.3 seconds to Maxi-
mum of 0.8 seconds.
Recommended Sensitivity Settings
Stick Electrode MAX
Short Circuiting MIG Midway between MIN & MAX
Pulsed and Spray MIG MAX
Gas Tungsten Arc TIG MAX
Plasma Arc Cutting/Welding Midway between MIN & MAX
Sensitivity Adjustment (#1)
The sensitivity adjustment will
make the lens more or less
responsive to dierent welding
processes.
It may be necessary to
adjust sensitivity based
on dierent light con-
ditions or if the lens is
ashing/ickering.
How to adjust sensitivity for dierent work-
place light conditions:
1. Turn sensitivity control to “MAX” setting.
2. Face the helmet towards surrounding work light
conditions. If the lens does not darken, you are
ready to weld. If the lens does darken, then move
on to step 3.
3. Gradually turn sensitivity setting lower until the
lens is no longer darkened by the work lighting,
you are ready to weld.
5.1 Variable Shade Knob
Use the control knob on the outside of the helmet to
adjust the lens shade in the dark state. Use the table
below to select the proper shade control setting based
on your welding process. Start at shade 13 and adjust
lighter to suit the welding application and your personal
preference. The knob should rotate easily.

WARNING:
If the sensitivity setting is
too low, then the lens will
not activate/darken or may
icker/ash during welding.
Stop welding immediately
and increase the sensitivity.
