b. Verify basic operation of the Pro-X5 before proceeding with the remainder of the
installation. Make sure all three rocker switches, two on the rear and one on the front of
the controller housing (see figures 5.1 and 5.2), are in the "O" (OFF) position. Install the
power cord plug into an appropriate electrical outlet supplying the proper ~(AC) power.
In all cases, connection should only be made to a circuit with a maximum 15A breaker
rating. Turn the main power rocker switch located on the front of the controller housing to
the "I" (ON) position. The temperature controller displays should illuminate.
c. Turn both rocker switches located on the rear side of the controller housing (see Figure
5.1) to the "I" (ON) position. This will turn on the Pre-Heat blower and heater and the
Plastic Heat heaters. The green and red LED's located below the Pre-Heat and Plastic Heat
controllers will illuminate. Use caution as the Pre-Heat exhaust air can be very hot. This
procedure verifies the Pro-X5 is receiving suitable power and the welder is functioning
properly. If the temperature controller displays and LED's illuminate as described you are
now ready to operate the welder. If the welder does not power-up as described, please
contact DEMTECH Services, Inc. or your authorized DEMTECH service center. Turn all
three rocker switches to the "O" (OFF) position and disconnect the AC power cord.
d. The operating voltage requirement for the Pro-X5 is 220-240 Volts AC only. This
operating voltage range refers to the actual voltage as measured at the welder power cord
plug after any extension cords while operating the welder under load. The following
procedure should only be performed by a qualified electrician. To measure the voltage
under load connect the welder to any extension cord(s) to be used and the proper AC source
which may be an in-field generator supplying the power. If applicable, start the generator
then turn all three rocker switches to the "I" (ON) position. While both the green and red
LED's located below the temperature controllers are illuminated, indicating that the Plastic
Heat and Pre-Heat heaters are active and after the cold start protection temperature has
been reached, power the drill motor by utilizing the trigger switch. Next, carefully separate
the plug at the end of the welder power cord just enough to expose the prongs without
disconnecting the power. Using a digital volt meter, measure the voltage under load
between the prongs. The measured value must be between 220 and 240 Volts AC.
