AUXILIARY POWER CONNECTIONS
The Precision TIG machines provide a standard NEMA
5-15R duplex receptacle, located on the upper case
back on the torch side of the machine:
• The bottom outlet of this duplex receptacle provides
switched 115VAC power for the Under-Cooler, or
Water Solenoid accessory. This Cooler receptacle
turns on when the arc starts and remains on for about
8 minutes after the arc goes out (with the Fan-As-
Needed machine cooling fan, see Maintenance
Section), so the Cooler’s fan and water pump will not
run continuously in idle, but will run while welding.
• The top outlet of this duplex receptacle provides at
least 8 amps at 115VAC, whenever the Precision TIG
Power switch is ON. This auxiliary circuit is intended
for running 115VAC accessories or small power tools.
Note: Some types of equipment, especially pumps
and large motors, have starting currents which are
significantly higher than their running current. These
higher starting currents may cause the circuit breaker
to open. (See next paragraph)
• Both the receptacle circuits are protected from shorts
and overloads by a 15 amp circuit breaker, located
above the receptacle. If the breaker trips, its button
pops out exposing a red ring. When the circuit break-
er cools, the button can be reset by pressing it back
in.
Note: When the breaker trips, not only will the auxil-
iary and cooler power be interrupted, but so will the
power to the shielding gas solenoid and machine
cooling fan.
The Precision TIG Export models also provide a
grounded 220vac Euro type Schuko receptacle and a
5 amp circuit breaker, located on the upper case back
on the reconnect side of the machine, intended for use
with a 220vac water cooler.
REMOTE CONTROL (If Used)
The Foot Amptrol or other Remote accessory, is
installed by routing the plug of its control cable up
through the left cable strain relief hole provided in the
base (see Figure A.2), then connecting the 6-pin plug
to the mating Remote receptacle behind the stud panel
cover. (See Operation Section B-2 for mating plug
wiring.)
Note: If the Precision TIG is equipped with an Under-
Cooler or Under-Storage unit, the Foot Pedal (or other
remote control accessory) and coiled control cable, or
excess cable length, may be conveniently stored in the
drawer while remaining connected.
