• Use this headshield for face and eye protection against harmful rays, sparks and spatter from welding and cutting.
• Never place this product on a hot surface.
• In the event of failure, the headshield remains protection against UV and IR radiation.
• Do not make any modifications to this product. Protection can be seriously impaired if modifications are made.
• When necessary, use identical replacement parts. This will ensure that the safety of the product is maintained.

Preparation & Use

Adjusting the Headband to Fit

1. The headband should be adjusted both in diameter and height to fit the wearer's head. To do this, press the adjustment knob on the back of the headband and turn the nut either left or right to expand or contract the headband.
2. The top headband can be adjusted by bending the strap and positioning the peg in the appropriate hole.
3. When the headband adjusting nuts are tight, the angle of tilt can be quickly and repeatably adjusted using the adjusting tab, by placing it on the chosen peg on the headband.

Using the Headshield

1. Remove the protective film from the lens cartridge. Remove the outer screen as on pages 5 & 6 to remove it from the forward surface. The lens will be set to Light DIN 4 state, & you will be able to see the workpiece. The lens will automatically darken when an arc is struck.
2. Test the lens by striking an arc on the workpiece for the first time. Check also that the outer screen and lens are clean and clear at all times.
3. Change the shade setting as required using the shade adjustment knob as described below. Refer to the table on page 5.

Select the Shade Setting

WARNING: DO NOT USE FOR WELDING OUTSIDE THE RANGE OF DIN 9-13. INJURY TO THE EYES & LOSS OF EYESIGHT MAY BE CAUSED.

On striking an arc, the light created will activate the solar cell and the window will automatically darken to a preset level. The lithium battery will provide the necessary energy to operate the headshield when there is no arc light. Because the cartridge assembly is a sealed unit, the battery cannot be replaced. You can adjust this shade level using the shade adjustment knob on the side of the headshield, corresponding to the type of welding process.

• There are five levels available; 9, 10, 11, 12 and 13. Check the table to determine which you should select.

1. Set the shade selector to the required setting.
2. During the welding operation the lens will automatically darken to the pre-set shade. On removal of the arc, the lens will return to the light state.
3. Adjust the 'Sensitivity' and 'Delay' using the switches inside the headshield.

Select the Grinding Setting

The headshield has a 'Grinding' setting, on the selector knob. When set to 'Grind' the auto darkening function is disabled. The headshield then provides eye and face protection for sparks and airborne particles created during grinding operations.

[Warning Symbol] WARNING: IT IS ESSENTIAL THAT AFTER USING THE HEADSHIELD IN GRINDING MODE, IT SHOULD BE RETURNED TO THE CORRECT SETTING BEFORE WELDING. FAILURE TO DO THIS COULD LEAD TO EYE INJURY.

Shade Selection Table

Shade numbers according to BS 379, DIN 4647-1 and EN 169.

Care & Maintenance

Damaged components must be replaced immediately to avoid risk of eye and face injuries. Periodically inspect the filter cartridge and lenses. Cracked, pitted or scratched lenses reduce vision and seriously reduce the level of protection and should be replaced with genuine, certified spare parts.

The outer screen can be removed for replacement and cleaning of the front lens.

For GWH5: Lift the front cover lens from the bottom edge with one finger and spring it away from the side retaining clips. When refitting, bend it until it can be sprung back under the side retaining clips, first on one side, then the other.

For GWH4 and GWH6: Press the textured buttons on each side of the headshield and ease the lens forward, unclipping it from the buttons. Reverse the process to replace or re-fit. Due to the small size of the components, the lithium battery cannot be replaced.

The cartridge can be wiped with a household glass cleaner when dirty. Apply the cleaner with a clean cloth or paper towel. DO NOT USE ALCOHOL TO CLEAN. DO NOT APPLY CLEANER DIRECTLY TO THE CARTRIDGE.

Clean all lenses with a soft tissue and suitable lens cleaning fluid. Do not use solvents. Never use tools or other sharp objects to remove material from the lens or screen. This may cause damage which may cause incorrect function and invalidate the warranty. Store the unit in its box or similar safe place.
