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 are a 6-Pin and a 14-Pin MS type recep-
tacle for connection of auxiliary 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 is
located on the case back.
220VAC RECEPTACLE
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.

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.
Note that the 42 VAC and 115 VAC circuits are electri-
cally isolated from each other. However, one line of
the 115VAC is connected to chassis ground.
