115VAC circuit is not present on IEC 974-1 European models.

As shipped from the factory Lead #21 from the 14 Pin connector is
connected to “-21” on the terminal strip. This is the configuration
for positive welding. If welding negative polarity, connect lead #21
to the “+21” connection point on the terminal strip.
AUXILIARY POWER AND
CONTROL CONNECTIONS
Located at the lower front of the welder behind a
hinged door is a 115VAC duplex receptacle for auxil-
iary power (Domestic and Canadian Models only) and
a 14 Pin MS type receptacle for connection of auxil-
iary equipment such as wire feeders. Also, terminal
strips with 115VAC and connections for auxiliary
equipment are located behind the access panel on the
lower case of the welder. A 220VAC receptacle for a
water cooler (European and Export Models only) is
located on the case back.
115VAC DUPLEX RECEPTACLE (DOMESTIC AND
CANADIAN MODELS ONLY)
The 115VAC duplex receptacle is protected by a cir-
cuit breaker located below the receptacle (see
Auxiliary Power Table). Receptacle is a NEMA 5-20R
(protected by a 20 amp breaker) on Domestic and
Canadian Models, except Canadian Code 10502
receptacle is a NEMA 5-15R, protected by a 15 amp
breaker.
220VAC RECEPTACLE (EUROPEAN AND EXPORT
MODELS ONLY)
A Continental European receptacle is located on the
rear panel for supplying 220VAC to a water cooler.
The receptacle has a protective cover to prevent inci-
dently contact and is a Schuko type. The circuit is pro-
tected by a 2 amp circuit breaker also located on the
rear panel. This circuit is electrically isolated from all
other circuits, but on the European Models one line is
connected to chassis ground.

14 PIN MS TYPE RECEPTACLE
(For MS3106A-20-27PX Plug. L.E.C. Part #S12020-32)
Refer to the figure A.4 for the available circuits in the
14 pin receptacle.
42 VAC is available at receptacle pins I and K.
A 10 amp circuit breaker protects this circuit.
115 VAC is available at receptacle pins A and J
(Domestic, Canadian and Export Models). This circuit
is protected by a circuit breaker (see Auxiliary Power
Table). Note that the 42 VAC and 115 VAC circuits
are electrically isolated from each other. However, on
the European model one line of the 115VAC is con-
nected to chassis ground.
