Cleaning Instructions - 3M Speedglas 9100 Bedienungsanleitung

SENSITIVITY
The sensitivity setting of the weld arc detection system can be
adjusted to accommodate a variety of welding methods and
workplace conditions. In order to see the current sensitivity
setting, momentarily press the SENS button. To select another
setting, press the SENS button repeatedly until the indicator
shows the desired setting, as indicated on the indicators.
Locked in light state (shade 3) at all times.
Position
Used for grinding (Not for Speedglas 9100
XXi).
Position 1 Least sensitive setting. Used if there is
interference from other welders' arcs in the
vicinity.
Position 2 Normal position. Used for most types of
welding indoors and outdoors.
Position for welding with low current or with
Position 3
stable welding arcs. (eg TIG welding)
Position 4 Suitable for very low current welding, use of
inverter type TIG welding machines.
Position 5 Most sensitive setting. Used for TIG welding
where part of the arc is obscured from view.
Position Locked in selected dark state. Same
function as a passive welding filter.
POSITION GRIND MODE (LOCKED LIGHT
STATE)
This setting could be used for grinding or other non-welding
activities.
SPEEDGLAS 9100V/9100X/9100XX
When the welding filter is locked in the light state (shade
3) the LED under the symbol will flash every 8 seconds to
alert the user. The welding filter must be unlocked before
arc welding is performed by choosing a sensitivity setting
for welding. When the welding filter turns OFF (after 1 hour
inactivity), it will automatically leave the locked state and go
to sensitivity setting 2.
SPEEDGLAS 9100XXi
To activate the grind mode, press and release (do not hold
down) the right side button of the silver front (see fig D:2).
The LED beside the grind symbol will flash every 5 seconds
to alert the user. To leave the grind mode, press and release
the button again. When the welding filter turns OFF, it will
automatically go to welding mode. Note that the welding
filter will turn off after 5 minutes of non-motion.
MEMORY FUNCTION (SPEEDGLAS 9100XXi)
This welding filter has a memory function that enables the
user to switch between two different weld settings.
When the first weld setting has been made, you have the
possibility to programme a second setting. By holding down
the right side button of the silver front (see fig D:2) for 2-3
seconds (The marked LED, on the illustration above, will
2
indicate (flashing) that you are in the second weld setting)
you can manually set the second program.
To switch between the two different settings, hold down the
right side button of the silver front 2-3 seconds. The LED will
indicate (flashing) the change of weld settings.
POSITION 1-5
If the filter does not darken during welding as desired, increase
the sensitivity until the welding filter switches reliably. Should
the sensitivity be set too high, the filter may remain in the dark
state after welding is complete due to ambient light. In this
case, adjust the sensitivity downward to a setting where the
welding filter both darkens and lightens as desired.
POSITION LOCKED
DARK STATE
When the welding filter is locked in the dark state and
the welding filter turns OFF (after 1 hour inactivity), it will
automatically reset to sensitivity setting 2. The shade
number to be used in the locked dark state, is selected by
the SHADE/ON button.
DELAY
The delay function should be used to set the recovery delay
of the welding filter from dark to light according to welding
method and current. See table fig. (E:3). The scale for the
from dark to light delay function is placed below the indicators.
COMFORT MODE FOR TACK WELDING.
(SPEEDGLAS 9100V/9100X/9100XX)
This setting may help reduce eye fatigue resulting from
the eye constantly adjusting to differing light levels during
tack welding. Tack welding mode uses an intermediate light
state (shade 5). If an arc is not struck within 2 seconds
the welding filter will switch back to its normal light state
(shade 3).
Note that the Sensitivity and Delay function are using the
same indicators on the display.
IN USE
To check that the electronics and buttons are working,
press the buttons and the indicators will flash. The batteries
should be replaced when the low battery indicator flashes or
indicators do not flash when the buttons are pressed.
The welding filter is equipped with three optical sensors
(see fig A:1). They react independently causing the filter to
darken when a welding arc is struck. The sensors on the
welding filter must be kept clean and uncovered at all times
for optimal function.
The recommended operating temperature range for the
product is -5°C to +55°C.
Flashing light sources (e.g. safety strobe lights) can
trigger the welding filter when no welding is occurring. This
interference can occur from long distances and/or from
reflected light. Welding areas should be shielded from such
interference.

CLEANING INSTRUCTIONS

Clean the welding filter and protection/cover plates with a
lint-free tissue or cloth.
To avoid damage to the product do not use solvents for
cleaning. Do not immerse in water or spray directly with
liquids.
