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.
Only qualified personnel should operate this equip- ment.
ADDITIONAL SAFETY PRECAUTIONS
Always operate this equipment with the filter installed and covers in place as these provide maximum protec- tion from moving parts and insure proper vacuum oper- ation and cooling air flow.
OPERATING INSTRUCTIONS
The 1GX vacuum can be operated in either the “On” or “Auto” mode by selecting the desired operation at the rocker switch on the motor housing. In the “On” posi- tion, the vacuum will be on continuously. In the “Auto” position, the “Auto On” light will be illuminated but the vacuum will only come on when the sensor detects welding current in the cable.
NOTE:The work cable must be routed through the cable holder on the motor housing in order for the “Auto” feature to work.
“Auto” operation of the vacuum will reduce shop noise when there is no welding being done. It will also increase the life of the vacuum motor and brushes dra- matically since, in semiautomatic welding, the unit will probably be off more than 50% of the time.
When utilizing the “Auto” feature, the operator should adjust the delay knob for the application. This knob will allow the vacuum to continue operating from 5 to 25 seconds after welding stops. The longer delay time should be used when:
•There is a series of very quick tack welds, so the vacuum doesn’t keep stopping and start- ing.
•In applications that cause the gun to run hot, the delay will help the gun cool off more quick- ly between welds.
•In very smoky conditions, the delay will help clear out more residual fumes.
