ing problems are observed and they persist, contact Everlast. Make
sure however, before you contact Everlast that polarity is correct for
the process being used. Improper polarity will result in poor welding
performance and in some cases, can result in no arc at all. See page
5 for more contact information.
NOTICE: Cosmetic damage claims
after 30 days will not be accepted, unless Everlast is contacted and
informed of such delay and reason for such a required delay (i.e.
Overseas in deployment).
GIVE YOUR UNIT SOME SPACE TO COOL.
This unit needs room to cool itself and maintain proper duty cycle.
Place the unit in a place that will allow
18”
from all sides to allow for
proper cooling. This welder pulls air in from the rear, and pushes it
through the unit
’
s heat sinks to cool the electronics. The air is then
exhausted through the front panel and side louvers of the unit. If any
of sides is blocked or restricted, the duty cycle will be reduced, and
overheating will occur, leading to possible damage if the restriction is
severe enough. Never attempt to restrict air flow by attaching filters
to the vents or by modifying your fans for
“
on demand
”
service.
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 welders, 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 typically be used as a conductor in a 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. If you are using this unit in conjunc-
tion with a 240V air compressor, you must supply a separate, dedi-
cated circuit for both. Do not share or piggy
-
back a circuit with this
unit. When 120V operation is required, simply connect the supplied
240V to 120V pig tail adapter. This adapts the unit from the NEMA 6
-
50 Plug to the NEMA 5
-
15 Plug to allow the unit to be used with
120V input without further modification of the welder. No wiring or
buss bar changes are required. Once the unit is plugged in, it will
automatically detect the new power and boot up in 120V mode. To
verify 120V mode, the display screen will reflect the power input
mode with one of the center tree information boxes displaying
“120
V
”.
To change back to 240V input, shut the machine down, un-
plug the adapter, and reconnect to the 240V power supply. Turn the
welder back on to reboot the unit back to 240V operation.
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. The red wire is not used.
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 modify, or attempt to 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
