1. It is essential that when replacing the battery that it is mounted
the correct way up as per the illustration. (p. 4)
TROUBLE SHOOTING
1. Not Switching – Stop welding immediately if the auto lens stays
light and will not darken. Review the sensitivity recommenda-
tions and adjust sensitivity. Clean lens cover and sensors of any
obstructions. Note! Make sure the sensors are clean and facing
the arc; angles of 45° or more do not allow the arc light to
reach the sensors.
2. Not switching – If the auto lens stays dark after the weld arc is
extinguished, or the auto-lens stays dark when no arc is pre-
sent. Fine-tune the sensitivity setting by making small adjust-
ments to the control by turning it toward the ‘Lo’ setting. In
extreme light conditions, it may be necessary to reduce the
surrounding light levels.
During testing or use, in case of any malfunctioning, please
suspend using it and contact your local sales agent.
