damage to the machine. One fan not working will cause duty cycle to
drop drastically. If your duty cycle warning appears unexpectedly,
and continues to do so, contact Everlast tech support for help on
checking fan operation and diagnosing the cause.
CONNECT YOUR UNIT TO POWER.
Your unit has been shipped with a NEMA 6
-
50P plug. This is the
standard plug used for 240V 1 Phase welders in North America. For
single phase 240V connection, select a NEMA 6
-
50 Receptacle for
operation with this unit. (Other regions/countries vary). A neutral is
not used. In a dedicated circuit, the wire wires supplying power (the
conductors and ground) are black, white and green. A red wire, which
is traditionally used as a
“
hot
”
leg (power conducting wire) of power
is not present in a three
-
wire 240V wire circuit of a welder. For weld-
ers, from the panel box, the black wire serves as L1(Hot), white
serves as L2 (Hot) and green serves as G (Ground). A red wire will
not be used as a conductor in a single phase 240V welder circuit. No
neutral wire is needed, so white is used as a
“
hot
”
conductor wire in
this instance. It is recommended to either install a receptacle as
close to the main panel as possible or install a subpanel cutoff as
close to the outlet and welder as possible. Always follow local codes
when making these connections. This unit should be used on a dedi-
cated circuit and should not share operation of another device on the
same breaker.
Setup Guide
Getting Started
NOTICE:
There are special rules centered around wiring service for a welding
machine. The National Electric Code under Article 630 has developed
specific set of electrical service regulations wiring for welding equip-
ment. These are different than for other types of service such as a
stove or dryer in a household or even in a commercial application.
You need to consult and/or employ a locally licensed electrician be-
fore installing this unit to make sure all national and local codes are
followed. Do not wire connections for this machine if you are not
qualified. Everlast is in no way liable for any damages caused by im-
proper connection of this unit. Your welder should be operated 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 configuration than
for an appliance with 4 wire operation. (Unless adapting with an ap-
proved 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. It is not used as a neutral.
The input
power cable conforms to North American standards for size, length,
with consideration given to inrush amperage, rated amperage and
duty cycle. Do not attempt to modify or rewire your unit.

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, this determines the conductor size. Refer your licensed, local
electrician to Article 630 of the NEC and the specification page of this
manual (or the specification grid printed on your unit) to select the
correct breaker and wire size. A delayed trip breaker, or slow blow
fuse should be used with this unit.
NOTICE:
The unit is designed with several features and functions in common
between processes. The principles of setup and operation carry over
from one process to another. In this case, information may not be
