SAFETY WARNINGS – READ BEFORE USING

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 Lincoln helmets are designed to protect the user against harmful

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.

WARNING

Refer to http://www.lincolnelectric.com/safety

for additional safety information.

HELMET INFORMATION

This Auto-Darkening Welding Helmet will automatically change from a light

state (shade DIN3.5) to a dark state (shade DIN9-13) when arc welding

starts.

The filter automatically returns to a light state when the arc stops.

Match your welding application to the shade indicated on the shade chart.

(See Page 6)

• Operating temperature: 14°F ~ 131°F (-10°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 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.

• Use only replacement parts specified in this manual.

• Do not use the helmet without inside and outside cover lenses properly

installed.

OPERATING INSTRUCTIONS

Headgear Adjustment

HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by pushing

in the Ratchet Knob and turning to adjust for the desired head size. This knob

is located at the back of the helmet. HEADGEAR CROWN ADJUSTMENT is

made by adjusting for comfort and snapping the pin into the hole to lock se-

curely in place.

TILT: Tilt adjustment is located on right side of helmet. Loosen the right head-

gear tension knob and push the top end of the adjustment lever outward until

the lever’s Stop Tab clears the notches. Then rotate the lever up or down to

the desired tilt position. The Stop will automatically engage again when re-

leased locking the helmet into position.

FORE / AFT ADJUSTMENT: Adjusts the distance between the user’s face

and lens. To adjust, loosen the outside tension knobs and slide forward or back

to desired position and retighten. NOTE: Make sure both sides are equally

positioned for proper 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 se-

lection chart on page 6). The variable shade control knob is located on the ADF cartridge as shown below.

Sensitivity Knob

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 right is the HIGH 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 left to reduce the sensitivity.

Delay Time Knob

This control is designed to protect the welder’s eyes from the strong residual rays after welding. Changing the

Delay Time knob will vary dark to light time between .1 second (minimum) to 1.0 second (maximum). Turning

the Delay Time knob to the left is maximum (1.0 second). This setting is recommended for high amperage ap-

plications where the weld puddle is still very bright after the welding arc has ceased and for situations where the

filter may be temporarily blocked from seeing the welding arc.

Power

This ADF cartridge is powered by replaceable batteries and solar power. Battery installation is required prior to

use. The batteries are located at the top of the ADF cartridge. Replace batteries when LOW BATTERY light is

lit. See the specification chart on page 3 for type of batteries required.

Weld/Grind Switch

Switch to be set to WELD for welding operation. After setting the switch to GRIND, a green LED on the

cartridge should blink every 3 seconds to indicate you are in Grind mode. GRIND setting is intended for grinding

only not for welding.

Test Button

Press and hold test to preview shade selection before welding. When released

the viewing window will automatically return to the light state (3.5 Shade).

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED BE-

is darkening properly. If cartridge is not darkening properly, replace batteries

with fresh batteries and test again before use. While welding, the arc and solar

cell will keep the ADF charged.

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.

(1) As arule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufcient 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 lter 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 lters may be used when the arc is hidden by the

workpiece.

CARTRIDGE AND LENS REPLACEMENT

Replacing Front Clear Cover Lens: Replace the front cover lens if it is damaged.

Remove ADF holder assembly per Figure 1. Remove front cover lens from helmet

assembly. Carefully remove gasket from cover lens. Install new cover lens into

gasket and assemble to helmet shell. Make sure to assemble cover lens and gas-

ket into helmet shell the same way as it was removed.

Replacing Inside Clear Lens: Replace the inside clear lens if it is damaged.

Remove ADF holder assembly per Figure 1. Remove shade cartridge from ADF

holder. 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: Remove ADF holder assembly from helmet shell.

See figure 1 for removal. Flex top end of the ADF holder to allow for ADF cartridge

to be removed from frame. Install new ADF cartridge into frame per figure 2 below.

Make sure that the ADF cartridge is inserted in ADF holder correctly as shown. In-

stall ADF holder assembly into helmet shell.

INSTALLING AN AFTERMARKET MAGNIFYING LENS:

Simply slide the magnifying lens into the short rail located on the sides of ADF

holder per Figure 3. Shade cartridge must be removed from ADF holder to install

magnifying lens.

Cleaning: Clean the helmet by wiping with a soft cloth. Clean cartridge sur-

faces 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.
