SAFETY WARNINGS – READ BEFORE USING
WARNING
ARC Rays can injure eyes and burn skin
• Before welding, always inspect helmet and filter lens to be sure they are fitted
properly, in good condition and not damaged.
• Check to see that the clear lens is clean and securely attached to the helmet.
• Always wear safety glasses or goggles under the welding helmet and protective
clothing to protect your skin from radiation, burns and spatter.
• Ensure that optical radiation from other welder’s arcs in the immediate area
does not enter in from behind the helmet and auto-darkening filter.
Note: Auto-darkening filters in Century®helmets are designed to protect the user against harm-
ful ultra-violet and infrared rays both in the dark and light states. No matter what shade the filter
is set to, the UV/IR protection is always present.
FUMES AND GASES can be dangerous to your health.
• Keep your head out of fumes.
• Use enough ventilation or exhaust at the arc or both to keep fumes and gases
from your breathing zone and general area.
• When welding with electrodes which require special ventilation such as
stainless or hard facing (see instructions on container or MSDS) or on
lead or cadmium plated steel and other metals or coatings which produce
highly toxic fumes, keep exposure as low as possible and within applicable OSHA PEL and ACGIH TLV limits using local exhaust or mechanical
ventilation. In confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are also required
when welding on galvanized steel.

This Auto-Darkening Welding Helmet will automatically change from a light state (shade 4) to a
dark state (Shade 9-13) when arc welding starts.
The filter automatically returns to a light state when the arc stops.
Shade control adjustments can be made while welding.
Match your welding application to the shade indicated on the shade chart. (See Page 4)
• Operating temperature: 23°F ~ 131°F (-5°C ~ 55°C).
• Do not use or open the auto-darkening filter if damaged by shock, vibration or pressure.
• Keep the sensors and solar cell clean. Clean the filter cartridge using a soapy water solution
and soft cloth which should be damp but not saturated.
This Auto-Darkening Welding Helmet is designed for use with GMAW, GTAW, MMAW, SMAW,
FCAW welding, or Plasma Arc and air carbon arc cutting.
The cartridge provides protection from harmful UV and IR radiation, in both dark and light states.
The cartridge contains two sensors to detect the light from the welding arc, resulting in the lens
darkening to a selected welding shade.
• Do not use solvents or abrasive cleaning detergent.
• If cover lens is spattered or covered with dirt, it should be replaced immediately.
• Do not use the helmet without inside and outside cover lenses properly installed.

Headgear Adjustment
Head Size Adjustment: Headband tightness is adjusted by pushing in the ratchet knob and
turning to adjust to desired comfort level. This knob is located at the back of the helmet. HEAD
GEAR CROWN ADJUSTMENT is made by adjusting crown strap for vertical placement on the
head and snapping the pin into the hole to lock securely in place.
Tilt: View angle is adjusted on both the left and right sides of helmet. Adjustment is made by
loosening outside tension knobs of headgear and releasing tilt lever from its current location and
moving it to another location. It is recommended this adjustment be completed one side at a
time. Retighten tension knobs when finished. The view angle adjustment needs to be set the
same for both tilt levers.
Fore/Aft Adjustment: Fore/Aft adjustment is the distance between the user’s face and lens. To
adjust, loosen the outside tension knobs to allow for headgear to be repositioned to a different
location. This should be done one side at a time and both sides should be located the same for
proper auto-darkening filter operation.
CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 9 to 13 based upon welding process or application (refer to
Shade selection chart on page 4). The variable shade control knob is mounted to shell for external
adjustment.
Solar Power
This helmet is powered by solar energy. As such, there is no battery that requires replacement.

As
a
rule
of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufficient view of the weld zone without going
below the
minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs
the
yellow or
sodium line the visible light of the (spectrum) operation
(2)
These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the
workpiece.
.
Data from ANSI Z49.1-2005
BEFORE WELDING. The helmet can be placed in sunlight to charge. Do
not store the helmet in a dark cabinet or other storage area for long periods.
While welding, the arc also charges the ADF cartridge.
SHADE GUIDE SETTINGS
If your helmet does not include any one of the shades referenced above, it is
recommended you use the next darker shade.

HELMET CARE AND MAINTENANCE
Figure 1
Figure 2Figure 3
Figure 1
Figure 2 Figure 3
Replacing Front Cover Lens: Replace the front cover lens if it is damaged
– cracked, soiled or pitted. Place your finger or thumb into recess (C) at the
bottom edge of the cover lens and flex the lens upwards until it releases from
the edges marked A and B. (Refer to figure 1).
Replace the Inside Cover Lens: if it is damaged (cracked, soiled or pitted).
Place your fingernail in recess above cartridge view window and flex lens
upwards until it releases from edges of cartridge view window.
Change the Shade Cartridge (See figure 2)
Fitting New Cartridge: Take the new shade cartridge and pass the poten-
tiometer cable under the wire loop before placing the cartridge into its retaining frame inside the helmet. Hinge down the wire loop and ensure the front
edge of the loop (D) is properly retained under the retaining lugs (E) as
shown in (figure 3).
Position the shade potentiometer to the inside of the helmet with the shaft
protruding through the hole. Secure potentiometer to shell. On the outside of
the helmet, push the shade control knob onto the shaft.
Cleaning: Clean helmet by wiping with a soft cloth. Clean cartridge surfaces
regularly. Do not use strong cleaning solutions. Clean sensors and solar cells
with soapy water solution and a clean cloth and wipe dry with a lint-free cloth.
Do NOT submerge shade cartridge in water or other solution.
Storage: Store in a clean, dry location.

TROUBLE SHOOTING GUIDE
Test your shade cartridge prior to welding by directing the front of the cartridge toward a bright source of light, then using your fingers rapidly cover
and uncover the sensors. The cartridge should darken momentarily as the
sensor is exposed. A torch striker can also be used.
