service and maintenance to the unit. Never pull or carry welder by the power cord or electrical connection.
Always keep slack in extension cord while in operation to avoid damage to the power connection. Keep hands
and other body parts clear of heating wedge and elements when hot. Do not operate near flammable materials.
Do not apply flammable liquids to seam area. Allow unit to cool down for at least 5 minutes before putting back
into shipping/storage case. Protect unit from exposure to direct rainfall or standing water. Never attempt to weld
in standing water.
Intended Use
For additional product information please refer to the product data sheet. The WGW 300 has been manufactured

Power Requirements
The voltage requirement of your WGW 300 hot wedge welder depends on voltage specified when ordered. WGW
300 will operate properly at 208VAC to 240VAC.
Note:
The above operating voltage ranges refer 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.
Generator Recommendation
If using house power from a building circuit, please contact the manufacturer for advice on plug and cord
