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 (included with the Precision TIG Welding Package), 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.
