SAFETY PRECAUTIONS
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.
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.
MAINTENANCE
– 32 –
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.
To avoid receiving a high frequency shock, keep the
TIG torch and cables in good condition.
