Section 2
Rear Panel Description and Explanation:
1. Gas Supply. Connect the Gas regulator hose to
this point via the brass barb fitting. (Regulator is
customer supplied and not provided as standard
equipment at time of publication.) The hose
barb connection must be tight to prevent gas
leakage. Install extra clamp if needed to pre-
vent gas from escaping.
2. Power Switch. Turns unit on or off. This is a 2
pole single phase 240V breaker-type switch. If
it is switched to the left, this means the unit is
switched off. If it is switched to the left, and the
unit is plugged into a good power supply, the
unit should power up. Note: When switched
off, the unit will continue to run and appear to
be switched on for up to 10 seconds as the ca-
pacitors discharge. This is normal. However, If
the unit will not switch off for some reason, the
switch may be damaged. Turn off the unit at
the main circuit breaker, and contact Everlast
technical. Do not continue to use.
3. Power Input Cable and NEMA 6-50P Plug. The
Power i-MIG 275S requires 220/240 V single
phase 50/60 Hz power input. If necessary this
unit will operate on 208V input as it is within th
e 10% voltage allowance. If actual voltage is
below 205 volts, the unit may not function cor-
rectly. If used on a generator, the generator
must labeled as "clean power" and provide less
than 5% THD. Consult your generator manufac-
turer for information regarding the clean power
rating on specific units. Everlast does not pro-
vide a list of approved generators. Manufactur-
ers rate their units as clean power independent-
ly according to industry standards. The plug is
the NEMA 6-50P. This is the standard plug for
welders operating on 240V in the US and Cana-
da. Other countries will have different configu-
rations.
4. Fuse. 30A, slow blow. This controls the main
power to the panel and fans. If the unit sudden-
ly stops, and no power to the panel is observed
and the fans are not running, first check the
main circuit breaker at the power panel and the
power switch position on the back. Reset if nec-
essary. If power isn't restored check this fuse.
It's a standard automotive type 30A slow blow
type available at many auto parts and electronic
supply stores. Fuses can blow from overload-
ing, circuit defect or simply from operation over
time. If the wire feeder quits feeding, and all
other signs are correct, it may be another fuse
Setup Guide and Component Identification
issue. The unit has an internal fuse on the
board which is a 5A fuse. If you suspect that
the internal fuse has blown, contact Everlast
technical support for information about replace-
ment.
5. Fans. The unit is equipped with a dual fan sys-
tem, which offers quieter and more efficient
cooling. It must operate free of obstruction to
preserve the high duty cycle which it offers.
Keep all objects or restrictions at least 12" from
all sides of if the unit for proper cooling. If pos-
sible allow 18". Allow the unit to rest on the
rubber pads/feet mounted on the welder. Do
not have the bottom of the unit supported di-
rectly on the metal pan so air can circulate
around the bottom as well. Do not run in an
enclosed space such as a cabinet or work box.
Do not grind or weld where sparks are directed
toward the rear of the unit or metallic particles
will build up on the fan blades and also on inte-
rior components. If metal builds up on the fan
blades, it can cause the them to vibrate and
ultimately fail.
6. Ground Bolt. The unit is equipped with an ad-
ditional grounding point for applications requir-
ing a bonded ground. Under most conditions,
the use of the ground is not required. Consult a
local licensed electrician for installation and use
of this connection.
