3. The 208/230 volt 50/60 Hz model POWER MIG is
shipped with a 7 ft.(2.1m). input cable and plug
connected to the welder.
4. Using the instructions in Figure A.2, have a quali-
fied 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. See
“Technical Specifications” at the beginning of this
chapter for proper wire sizes. For long runs over
100 feet, larger copper wires 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 when the welder
plug is inserted into a grounded receptacle.

OUTPUT POLARITY CONNECTIONS
The welder, as shipped from the factory, is connected
for electrode positive (+) polarity. This is the normal
polarity for GMA welding.
If negative (–) polarity is required, interchange the
connection of the two cables located in the wire drive
compartment near the front panel. The electrode
cable, which is attached to the wire drive, is to be con-
nected to the negative (–) labeled terminal and the
work lead, which is attached to the work clamp, is to
be connected to the positive (+) labeled terminal.
