1
Water Cooler Plug (240V 1ph, 4A max)
This plug is to be used with Everlast water coolers only. Do not use with any other application.
2
Input Cable and Plug*
North America only:
The unit may be operated on either 208
-
240V 1 phase (or on 120V 1 phase with the included pigtail
adapter). North American standards require only 3 wires for 1 phase operation of welders. A neutral is not used or required.
For wiring a 1 phase connection to the unit: Use Black for L1, White for L2, and Green for ground (not neutral) use. Red is not
typically used in wiring a dedicated welder circuit. This is in accordance with North American codes for welder wiring (see
Article 630 of the NEC for more info). However, this presents a problem when wiring into old services where red may be
present where a 4 wire system or older 3 wire is used with a neutral (white wire) and a ground (green wire). While a welder
operates on 240V single phase, a Neutral is not used and the white and black wires are used as conductors for a dedicated
welder circuit. If a red wire must be used as a conductor, then the black conductor should be matched to the black wire on the
welder and the red conductor should be matched to the white wire on the welder. When operating on 120V, the white wire
(internally) becomes the neutral, and the green still serves as the ground.
The supplied NEMA 6
-
50P is the proper plug used
for wiring single phase 240V welders in North America. It should not be changed or removed unless wiring directly into a cut
-
off switch. Other regions may vary and may have a different plug type or no plug at all.
3
HF Ground Service Bolt**
For use in a combined effort to mitigate any electrical interference that may be caused by the HF start of this unit.
4
Shielding Gas Inflow Connector
(5/8”
CGA)
North America:
5/8”
CGA connector.
Other Markets:
Hose Barb connection.
5
Fan location
Periodically check for proper fan function and cleanliness.
6
Breaker/Power Switch.
This switch doubles as the main power switch and disconnect switch. If this switch trips and the welder power turns off, a
significant internal event or failure of the switch
may
have occurred. If this occurs, immediately remove from service and mark/
tag according to regulations and contact Everlast Tech Support for further diagnosis and/or repair options.
7
Air Regulator Bracket Screw Holes (On some
models. Not all models may have these
screw holes. Exact location may vary.)
The air regulator bracket may be connected to this location. Alternately, the pair of screws (left side from this view) near the rear
of the metal cover may be used to install the bracket. If no screw holes are present, then use the alternate location on the side
to mount the air regulator bracket. If present, exact location may vary due to manufacturing changes.
NOTICE: Always consult national codes
and a local licensed electrician before
wiring this welder to any service.

**NOTICE:
If any electrical disturbance is noticed as a result of the High Frequency operation of this unit during arc starting, the HF service bolt should be connected directly to a 12 gauge wire that is
bonded directly to an outside copper ground rod driven into moist soil. Additionally, all metal items including any metal frame or sheeting of the building should be connected and ground-
ed to separate copper ground rods driven into the ground at 10 foot intervals around the perimeter of the building. This includes items such as tables, carts, rack material, metal surrounds,
etc. that may act as
“
antenna
”
to radiate/absorb HF energy. Additionally, all cords and welding leads should be twisted together and run directly to the work without coils or excess cabling.
