Fitting
Before donning the welding helmet, connect the hose to the visor and power unit and fit the waist belt with the buckle at the front. Check that air is coming out of
the front of the inner air channel. Ensure the sensors on the ADF are clean and unobscured. Make sure that the ADF holder is fitted tightly and that the fastener
on the ADF is closed.
Don the welding helmet and adjust the crown strap to achieve a comfortable fit with the headband above the ears. Adjust the head harness to the correct size
using the rear ratchet knob. Flip the welding helmet down and pull the face seal under the chin ensuring a snug fit around the face.
Tighten the drawstring.
For optimum viewing, the angle of the headband inside the welding helmet can be adjusted.
Head/Face seal removal/replacement
The head /face seal is fixed to the welding helmet by means of Velcro, to replace:
1. With the helmet placed on a flat surface, detach the hose assembly from the Air channel by holding the air channel firmly and twisting the bayonet fitting
anti-clockwise.
2. Detach the old Head/face seal from the Velcro.
3. Attach the head/face seal Velcro to the helmet Velcro, starting from the centre point follow the contours of the helmet ensuring that the joint is flat, even
and without creases.
Sweatband/head comfort pad removal/replacement
Both Sweatband and head comfort pad can be replaced very easily.
To replace Sweatband:
1. Remove 2 x ¼ turn bolts from air channel.
2. Remove old sweatband.
3. Locate the 4 x punched holes of the replacement sweatband over the 4 x headband retaining lugs.
4. Locate 2 x ¼ turn bolts into air channel and secure.
5. Fold sweatband over headband and locate on lugs.
To replace head comfort pad:
1. Remove the old comfort pad, clean Velcro surface of any residue debris.
2. Refit new comfort pad, locate centrally on the headband and press Velcro firmly into place.
Cleaning
Wipe with a damp (not wet) soft cloth soaked with warm soapy water to clean the welding helmet, face seal and hose. Take care when cleaning outer/inner
lenses as they may scratch. Dry by wiping with a soft dry cloth and allow to air dry.
Do not allow water to enter the air channel. WARNING: Do not clean
with commercial solvents or organic compounds.

To replace the ADF lens, simply move the switch at the bottom to the unlock position and pull slowly away from the helmet. The Battery and external switchgear
need to be removed, by carefully pushing out the retaining clip at the top, releasing the locating slot at the bottom of the battery pack.
Weld/Grind Setting
Depending on whether you would like to weld or grind, set the weld/grind mode switch to the corresponding position.
Shade setting
In weld mode, select the shade in accordance with EN 379 (see table below).
To set the light sensitivity/delay:
a. Set the control dial for light sensitivity to position HI (maximum light sensitivity).
b. Slowly turn the control dial for light sensitivity counterclockwise until the ADF is no longer getting darker. The LO setting is suitable for high amperage
welding and welding in bright conditions. The HI setting is suitable for low amperage welding, poor light conditions and TIG welding. We recommend using
a higher sensitivity setting with this ADF.
c. Set the delay from dark to light (0.1s MIN to 0.9s MAX) as required. The MIN setting is ideal for tack welding or production welding with short welds.
The MAX setting is ideal for high amperage welding where there is an afterglow from the weld.
The power supply
The power supply for the R23AWH 9/13 ADF is provided by solar cells and one replaceable CR2450 lithium battery. Turning the ADF on or off is automatically
controlled.
Low battery warning light
The low battery warning light will flash when the battery is low.
Grind flash
The grind light will flash when using grind function.
WARNING: To avoid any harm to eyes, do not conduct welding while on grinding mode
