CORE SERIES WELDING HELMET
OPERATING MANUAL
Sensitivity Control
The responsiveness to different light levels in various welding processes can be adjusted in
the range from low to high.
Set the
Sensitivity Dial (3) to your preferred level. Turn the dial counter-clockwise
arrow-rotate-left
to
decrease sensitivity, and rotate it clockwise
arrow-rotate-right
to increase sensitivity.
Low Sensitivity
• Suitable for high amperage welding and welding in bright light conditions (lamp light
or sunlight).
High Sensitivity
• Suitable for low amperage welding and use in poor light conditions.
• Suitable for use with steady arc process such as TIG welding.
• Under normal use, a higher sensitivity setting is recommended.
Delay Control
The length of time delay for the ADF to return to the light state after welding can be
adjusted in the range from fast to slow (0.1-0.9s). The time delay is for the protection of the
welder’s eyes from strong residual rays after welding.
Set the
Delay Dial (4) to your preferred level. Turn the dial counter-clockwise
arrow-rotate-left
to
decrease delay time, and rotate it clockwise
arrow-rotate-right
to increase delay time.
Low Delay
• The time the ADF takes to lighten after welding becomes shorter. The shortest time is
about 0.1s depending on the welding point temperature and shade setting. This setting is
ideal for tack welding or production welding with short welds.
High Delay
• The time the ADF takes to lighten after welding becomes longer. The longest time is
about 0.8s depending on the welding point temperature and shade setting. This setting is
ideal for welding at high amperage where there is an afterglow from the weld.
Grind Mode
Press the Grind Mode Button (6) to initiate grind mode. Upon activation, the Grind Mode
Indicator (2) light will begin to blink. To deactivate grind mode and revert back to weld
mode, simply press the Grind Mode Button (6) again.
Note: Do not weld in the grind mode, the ADF will not darken.
Low Battery Indicator
When the backup battery is low, the Low Battery Indicator (1) will begin to blink. Replace
the battery when it is low, otherwise the ADF switching time will become slower, and shade
accuracy will be compromised.
