Read and understand this entire section before oper-
ating your SF2400 Stationary Fan System.
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.
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.
------------------------------------------------------------------------
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
Use the wall-mounted starter/overload switch or the
hood-mounted remote switch (if a lamp kit is installed)
to turn on the SF2400 Stationary Fan.
Position hood within 10-15 inches (250-400 mm) of
the arc.
If using a Lamp Kit:
• The switch on the hood with a lamp symbol
operates the work lamp in the hood.
• The 0/1 switch operates the SF2400 Fan.
If using an Auto Start/Stop Arc Sensor:
Leave the 0/1 switch in the 0 (off) position. The arc
sensor will automatically switch the fan on when it
senses an arc. Standard run-out time is approximately
20 sec. The work lamp operates independently of this
sensor.
If using a Statiflex 200-M filter unit:
DO NOT USE FOR CUTTING OR GOUGING OPER-
ATIONS. The Statiflex filter unit is recommended for
light duty or intermittent use. Although it can be used
in production applications, this may require very fre-
quent maintenance or replacement of the filter car-
tridge. Use of the Statiflex 200-M disposable filter sys-
tem is cost effective if consumable use at the station
is less than 1500 lbs. per year of solid wire or 1100
lbs. per year of flux-shielded consumables.
STATIFLEX FILTER MAINTENANCE INDICATOR
With use, the filter will fill up with collected fume.
When using the machine, regularly check the mainte-
nace indicator on the front panel of the machine. The
indicator will move gradually from white to red as the
filter becomes saturated, letting you know ahead of
time how close the filter is to clogging.
When the maintenance indicator shows that the filter
is clogged, it is time to replace the filter.
