CONNECT YOUR UNIT TO THE OUTLET.
Your unit has been shipped with a NEMA 6
-
50P welder plug. This is
the standard for 240V 1 Phase welders in North America. For single
phase 240V connection, select a NEMA 6
-
50 Receptacle for opera-
tion with this unit. (Other regions/countries vary). A neutral is not
used. For a dedicated circuit, the wire wires supplying power (the
conductors and ground) are black, white and green. A red wire,
which is traditionally the
“
hot
”
leg of power is not present in the three
wire 240V wire circuit of a welder. For welders, from the panel box,
the Black wire serves as L1(Hot), White serves as L2 (Hot) and Green
NOTICE:
There are special rules centered around wiring an outlet for service
with a welding machine. The National Electric Code under Article
630 has developed specific regulations for wiring electrical service
for welding equipment. These are different than for other types of
service such as a stove or dryer in a household or even in a com-
mercial application. You need to consult and/or employ a locally
licensed electrician before installing this unit to make sure all nation-
al and local codes are followed. If you are not qualified to make
these connections, don
’
t. Everlast is in no way liable for any damag-
es caused by improper connection of your welder. Your welder
should be on a dedicated branch circuit not far from an electrical
disconnect box. Importantly, it should not share circuits with other
shop or household items. Do not attempt to
“
adapt
”
existing circuits
because conductor (wire) colors are different for welders with 3 wire
operation than for a dryer or range with 4 wire operation. (Unless
adapting with an approved adapter when being powered with a
“
clean power
”
generator.) No neutral is used in a welder circuit. The
white wire is a conductor in a single phase welder service. The red
wire is not used.
The input power cable conforms to North American
standards for size, length, with consideration given to inrush amper-
age, rated amperage and duty cycle. Do not modify, or attempt to
rewire your unit.

serves as G (Ground). Red will not typically be used as a conductor
(on a dedicated welder circuit). There is no need for a neutral, so white
is used as the other
“
hot
”
conductor in this instance. It is recommend-
ed to either install the receptacle as close to the main panel as possible
or install a subpanel cutoff as close as possible to the outlet and weld-
er. Follow local code to determine best arrangement.
If you are using this unit in conjunction with a 240V air compressor,
you must supply a separate, dedicated circuit for both. Do not share or
piggy
-
back a circuit with this welder/cutter unit.
This welding unit is also designed to operate on 120V power. While
operating on 120V, the output will be reduced. To adapt the unit for
120V operation, the unit has been supplied with a 240V to 120V pigtail
adapter. When operation on 120V is required, simply plug this NEMA

50R to 5
-
15P adapter to any standard type wall outlet with either a
slow blow fuse, or delayed trip breaker protecting the circuit. The in-
rush current of this unit can exceed the limits of a typical 15A 120V
circuit when used at or near maximum output of this welder while oper-
ating on 120V. For best results, use this unit with a slow blow fuse, or
a delayed trip breaker on a dedicated 120V 20 or 30 Amp circuit to
avoid nuisance fuse blowing or breaker tripping. There is no need to
alter or change any wiring or switching required to be able to operate
on 120V. The unit automatically senses the input power and adjusts
the maximum output of the welder.
Getting Started
Selecting A Breaker and Wire Size
Select a breaker based off of the I
1MAX
rating of this unit. This is the
maximum inrush current of the unit. The inrush is not a sustained
current. The I
1EFF
rating of the unit is the maximum
“
rated
”
current of
the machine. When combined with the length of the run from the
main panel, his determines the conductor size needed to supply the
welder, Refer your electrician to Article 630 and the specification page
of this manual (or the specification grid printed on your unit) when
selecting the correct breaker and wire size. A delayed trip breaker, or
slow blow fuse should be used with this unit.
