Electrical Plug Connection
a. The Pro-Wedge 3XL is supplied with a power cord permanently connected to the front of
the welder through a right-angle strain relief. Depending on the intended country of use
the plug at the other end of the power cord will vary but in all cases must be rated for the
voltage and current requirements of the welder. It is highly recommended to use a twist-
lock or twist-to-connect type plug with a permanent ground connection. Refer to the
welder serial plate affixed to the inside side of the Side Frame near the Upper Nip Arm
for the voltage and current requirements of the welder. Connect the power cord and plug
to an appropriate electrical outlet supplying the proper ~(AC) power.
connection should only be made to a circuit with a maximum 20A breaker rating.
b. Verify basic operation of the Pro-Wedge 3XL before proceeding with the remainder of
the installation. The welder utilizes a rocker power switch on the main controller panel
of the welder. Toggle the switch left to turn the welder ON. Toggle the switch right to
turn the welder OFF. Toggle the main power switch to the ON position.
c. The various control LED/LCD displays should turn on. This procedure verifies the Pro-
Wedge 3XL is receiving suitable power and the controller is functioning properly. If the
welder powers-up 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.
d. The operating voltage requirement for the Pro-Wedge 3XL is 220-240 Volts AC only.
This operating voltage range refers to the actual voltage as measured at the welder power
cord input plug after any extension cords while operating the welder under load. The
following procedure should only be performed by a qualified electrician.
measure the voltage under load connect the welder to any extension cord(s) used and the
generator supplying power. Start the generator and turn both welder power switches to
the ON position. While the Number 1 indicator light on the temperature controller is
illuminated and the wedge is heating, separate the plug at the end of the welder power
cord just enough to expose the prongs but 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.
