SAFETY INSTRUCTIONS
Do not attempt to use this equipment until you have
thoroughly read all operating and maintenance man-
uals supplied with your equipment and any related
welding machine it will be used with. They include
important safety precautions, operating and mainte-
nance instructions and parts lists.
WARNING
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts such
as output terminals or internal wiring.
•Insulate yourself from the work and
ground.
•Always wear dry insulating gloves.
------------------------------------------------------------------------
WELDING SPARKS can cause fire or
explosion.
•Keep flammable material away.
•Do not weld upon containers which
have held combustibles.
------------------------------------------------------------------------
ARC RAYS can burn.
•Wear eye, ear and body protection.
------------------------------------------------------------------------
FUMES AND GASES
can be dangerous.
• Although the removal of the particu-
late matter from welding smoke may
reduce the ventilation requirement,
concentrations of the clear exhausted
fumes and gases may still be haz-
ardous to health. Avoid breathing
concentrations of these fumes and
gases. Use adequate ventilation
when welding. See ANSI Z49.1,
"Safety in Welding and Cutting", pub-
lished by the American Welding
Society.
------------------------------------------------------------------------
OPERATION
Only qualified personnel should operate this equip-
ment.
ADDITIONAL SAFETY PRECAUTIONS
Always operate this equipment with the filter and arm
installed and all covers in place as these provide max-
imum protection from moving parts and insure proper
vacuum operation and cooling air flow.
OPERATING INSTRUCTIONS
To use the Automatic Start/Stop Arc Sensor, leave the
0/I switch on the hood (See Figure 5) in the 0 (off)
position (If using a Mobiflex 200-M, the Start/Stop
switch must be in the "Start" position). When an arc is
sensed, the sensor will turn on the connected extrac-
tion system automatically. When the arc is no longer
detected, the sensor will shut the system down after
20 seconds.
Refer to Figure 5:
A. Switch with Lamp Symbol - Operates Lamp.
B. Switch with 0/I- Operates connected extraction fan
For optimum fume-capture, position hood within 10-15
inches (250-400mm) of the arc.
