SAFETY WARNINGS – READ BEFORE USING

WARNING

ARC Rays can injure eyes and burn skin

• Before welding, always inspect the helmet and filter lenses 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, 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 that require special ventilation such as stainless or hard facing (see instructions on the 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.

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 3) to a dark state (Shade 7-13) 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 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 cells 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 detergents.
• If the 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.

SPECIFICATIONS

(1) Headgear compliance with ANSI Z87.1 is without a sweatband installed.

OPERATING INSTRUCTIONS

Headgear Adjustment

HEAD SIZE ADJUSTMENT: HEADGEAR TIGHTNESS is adjusted by pushing in the Ratchet Knob and turning it 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 securely in place.
TILT: Tilt adjustment is located on the right side of the helmet. Loosen the right headgear 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 forward or back to the desired tilt position. The Stop will automatically engage again when released locking the helmet into position.
FORE / AFT ADJUSTMENT: Adjusts the distance between the user’s face and the lens. To adjust, loosen the outside tension knobs and slide forward or back to the 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 7 to 13 based on the welding process or application (refer to the Shade selection chart on page 6).
The variable shade control knob is mounted on the exterior of the helmet shell.
Grind mode can be selected by rotating the shade control knob counterclockwise till an audible click is heard.
Grind mode is intended for grinding only not for welding.

Sensitivity Knob
You can adjust the light sensor by turning the Sensitivity knob to the left or right as shown in the figure below. Generally, turning the knob all the way to the right, or the highest
setting, is selected for normal use. When the 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 seconds). This 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 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 the LOW BATTERY light is lit. See the specification chart on page 3 for the type of batteries required.

Variable shade control Knob

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED BEFORE WELDING.
The TEST button is for the user to verify the ADF cartridges darkening properly. If the cartridge is not darkening properly, replace batteries with fresh batteries and test again before use. While welding, the arc, and the solar cells will keep the ADF charged.

(1) As a rule of thumb, start with a shade that is too dark, then go to a lighter shade that gives a 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 in 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

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

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). Use only the replacement front cover lenses specified in this manual.
Replace the Inside Cover Lens: if it is damaged (cracked, soiled, or pitted). Place your fingernail in the recess above the cartridge view window and flex the lens upwards until it releases from the edges of the cartridge view window.
Change the Shade Cartridge (See figure 2)
Fitting New Cartridge: Take the new shade cartridge and pass the potentiometer 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.
Installing an Aftermarket Magnifying Lens: Unclip the wire loop (D) from retaining lugs (E) and move the hinge up. Place magnifying lens over ADF viewing area and retain with the wire loop.
