b-1 OPERATION b-1

Read and understand this entire section before oper- ating your SF2400 Stationary Fan System.

Only qualified personnel should operate this equip- ment.

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.

------------------------------------------------------------------------

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.

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.

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.
