MAINTENANCE
SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
•Only qualified personnel should perform this maintenance.
•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.
•Do not touch electrically hot parts.
WARNING
4.If the TIG Module is used in locations where there are large amounts of conductive metal or salt particles in the air, it is recommended that the inside rear assembly of the TIG Module be cleaned out with clean, dry, low pressure compressed air on a regular basis (monthly, for example). To do so, first be sure that the input power has been removed from the TIG Module. Remove the case wraparound. This exposes the spark gap, high voltage transformer, high frequency transformer, and other components. Clean this area with compressed air.
To avoid receiving a high frequency shock, keep the
TIG torch and cables in good condition.
PERIODIC MAINTENANCE
Very little maintenance is required to keep your TIG Module in top operating condition. No specific schedule can be set for performing the following items; factors such as hours of usage and the machine environment should be considered when establishing a maintenance schedule.
1.Periodically blow off dust and dirt which may accumulate on the outside of the TIG Module.
2.Inspect the welding and control cables for fraying, cuts and bare spots.
3.Inspect the spark gap at regular intervals to maintain the recommended spark gap setting. Use the following procedure:
The spark gap is set at the factory for a gap of 0.015(.38mm) inches. This setting is proper for most applications.
To adjust the spark, first be sure that the Ranger welder is off, and that the input cable is disconnected from the Input Receptacle on the back of the TIG Module. Remove the outer case wraparound, and find the spark gap assembly located at the top right hand side of the internal compartment. Check the spark gap setting with a feeler gauge. If adjustment is required, loosen one of the Allen head screws which secure the spark gap electrodes in place. Set the gap, and tighten the screw. Reinstall the case wraparound.
