The power supply
2.
The power of M23AWH 9/13 helmet is provided by solar cells with one lithium battery. Turning on or off is automatic controlled
by circuit. You can use this helmet at any time you need and take it away after working without operating any key. Using this
helmet is fully free like glass filter helmet.
Darkness selection
3.
Striking the arc, the observing window darkens immediately. At this moment, according to the technical requirement, the operator
adjusts the darkness knob 13 in the direction as shown by the arrow to select the optimum darkness.
Move the knob 17 leftward to choose shade from 5-9 and rightward to choose shade from 9-13.
Please refer to page 8 for shade recommendations.
Delay time selection
4.
By moving the DELAY selector knob 22 on the rear of the cartridge, the time taken for the lens to lighten after welding can be
altered from 0• 1-0.9 second.
Turn to MIN: The time the lens lighten after welding changes to be shorter. The shortest time is about 0.1 second depending
upon welding point temperature and shade set. This setting is ideal for track welding or production welding with short welds.
Turn to MAX: The time the lens lighten after welding changes to be longer. The longest time is about 0.9second depending
upon welding point temperature and shade set. This setting is ideal for welding at high amperage where there is an after glow
from the weld.
Sensitivity selection.
5.
By moving the SENSITIVITY selector knob 21 on the rear of the cartridge, the sensitivity to ambient light changes can be altered.
Turn to LO: The photosensitivity changes to be lower.
Suitable for high amperage welding and welding in bright light conditions (lamp light or sun light).
Turn to HI: The photosensitivity changes to be higher.
Suitable for low amperage welding and using in pool light conditions.
Suitable for using with steady arc process such as TIG welding.
If the helmet can be used normally, we suggest using this helmet with a bit high sensitivity.
Because the shape of man's head varies from person to person. The work position and the observing angle is different, operator
