3 Sensitivity Control
The sensitivity control is used to make the lens more
responsive to differing light levels experienced in various
welding processes. We recommend a Mid-Range setting
for most applications. See Adjusting Sensitivity and
Recommended Sensitivity Settings sections following.
It may be necessary to adjust helmet sensitivity to
accommodate different lighting conditions or if lens is
flashing On and Off.
Adjust helmet sensitivity as follows: adjust helmet
sensitivity in lighting conditions helmet will be used in.
1. Turn sensitivity control to lowest setting.
2. Press On/Off Button to turn helmet On. Helmet lens will
darken twice and then clear.
3. Face the helmet in the direction of use, exposing it to
the surrounding light conditions.
4. Gradually turn sensitivity setting clockwise until the lens
darkens, then turn sensitivity control inside the mask
until slightly past setting where lens clears. Helmet is
ready for use. Slight readjustment may be necessary for
certain applications or if lens is flashing on and off.

4 Lens Delay Control
The lens delay control is used to slow the lens-switching
time to the clear state after welding.
The delay is particulary useful in eliminating bright after-
rays present in higher amperage applications where the
molten puddle remains bright momentarily after welding.
Adjusts from (10 second-Min. to 1.0 second-Max).
5 Low Battery Indicator
The auto-darking lens AUTOMATIC V4 - 9/13 contains 2
AAA/LR03/1,5V batteries. The low battery indicator lights
when 2-3 days of battery life remain.
Procedure for replacing cartridge and
cover plate.
• Do not use the AUTOMATIC V4 - 9/13 helmet without the
inside and outside lens covers properly installed.
Welding spatter will damage the autodarkening lens
voiding the warranty.
You should change cover plate when it is broken, is
scratched and is dirtied from spatter.
1. Outside: Place the helmet on a flat surface. Grasp the
front lens holder with one hand while pushing the inside
retaining clips of the lens outward. Do one side at a
time, gently pulling the front lens holder away from the
helmet as each tab is released from its retaining clip.
Once released, the outside cover lens can be replaced.
2. Inside: remove the inside lens cover by following the
procedure in step 1. With the auto-darkening lens
removed from the helmet, remove the inside cover lens
by prying the lens up at the thumbnail opening located
at the top centre of the auto-darkening lens. Replace
the lens by gently bowing it in the center and inserting
it, one end a time, into the retaining clips located on the
outside of the auto-darkening lens assembly.

3. Reinstalling auto-darkening lens assembly: gently place
autodarkening lens in front of the helmet (be careful not
to drop lens). Install front lens cover with gasket. Grasp
front lens holder and slowly insert the six retaining
pieces into front of the helmet. (Make certain you gently
squeeze the outside edges of the front lens holder while
inserting tabs into helmet). From the inside of the
helmet, gently push the retaining tabs in to secure the
font lens holder in place.

Troubleshooting

Symptom
Not switching: auto-lens stays
light and will not darken when
welding
Sections of the auto-lens are
not going dark, distinct lines
separate the light and dark
areas.
Switching or flickering: the
auto-lens darkens then ligh-
tens while the welding arc is
present.
Inconsistent or lighter auto-
lens shading in the dark state,
noticeable on the outside
edges and corners.
Warranty
Your AUTOMATIC V4 - 9/13 helmet warranty is for 24
months against workmanship and defects. For warranty

The warranty does not cover improper handling, abuse or
use in any other application other than recommended. In
the case of a warranty claim, contact your WELDTEAM
distributor who will process your claim. Please present
your original sales receipt for warranty verification.

Solution
Stop welding immediately. Clean lens
cover and sensors of any obstructions.
Make sure the sensors are facing the
arc, angles of 45° or more may not
allow the arc light to reach the sensors.
Stop welding immediately: the autolens
may be cracked which can be caused
by the impact of dropping the helmet.
Weld spatter on the auto-lens may also
cause cracking. (The lens may need to
be replaced, most cracked lenses are
not covered by warranty).
Make sure that the arc sensors are not
being blocked from direct access to the
arc light. Check the lens cover for dirt
and spatter that may be blocking the
arc sensors.
Referred to as an angle of view effect,
auto-darkening lenses have an optimum
viewing angle, perpendicular 90° to the
surface of the auto-lens.
