1. Before starting the installation, check with the local power
company if there are any questions about whether your power
supply is adequate for the voltage, amperes, phase, and
frequency specified on the welder rating plate. Also be sure
the planned installation will meet the U.S. National Electrical
Code and local code requirements.
2. Using the instructions in Figure B.2, have a qualified
electrician connect a receptacle (Customer Supplied) or cable
to the input power lines and the system ground per the U.S.
National Electrical Code and any applicable local codes. For
cords over 100 foot, larger copper conductors should be
used. Fuse the two hot lines with super lag type fuses as
shown in the following diagram. The center contact in the
receptacle is for the grounding connection. A green wire in
the input cable connects this contact to the frame of the
welder. This ensures proper grounding of the welder frame

Connect to a system grounding wire. See the United States
National Electrical Code and/or local codes for other details and
means for proper grounding. Connect to hot wires of a three-wire,
single phase system.
WARNING
This welding machine must be connected to a power source
in accordance with applicable electrical codes.
WARNING
Do not connect the machine to an input power supply with a
rated voltage that is greater than 125 volts.
Do not remove the power cord ground prong.
