Power Requirements

The voltage requirement of your Pro-Wedge is 220-240 Volts AC only.
Note:
The above operating voltage range refers to actual voltage at point of welder plug-in.
In other words, the voltage under load at the welder end of the extension cord. To measure voltage
under load, connect the welder to the extension cord and generator that will be used. 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 welders power cord just enough to expose the prongs. Using a digital voltmeter,
measure the voltage under load between the hot and neutral prongs.
This procedure should only be performed by a qualified electrician.
