LEFT SIDE PANEL
The left side panel of the main control contains
the following features:
MAIN POWER ON/OFF SWITCH:
This power switch provides power to
the main control, carriage and the remote
pendant.
AC POWER CORD:
The main control is available with three
input voltages options 42V, 115V & 230V.
AC POWER FUSE:
This fuse provides protection to the AC
circuitry of the PIPE KAT
®
. The rating of the
fuse depends on the voltage of the unit, 42V
unit is supplied with a 10 Amp fuse, 115V unit
is supplied with a 5 Amp fuse, and the 230V
unit is supplied with a 2.5 Amp fuse.
WARNING! Never change the fuse with
one of a different rating; this could damage the
PIPE KAT
®
unit.
WELDING POWER SOURCE INTERFACE
CONNECTION:
This connector is used to communicate
to the welding power source. It provides the signal for the arc start when the PIPE KAT
®
wants
the welding power source to weld. In addition there is an analog control signal for remote
welding voltage control and wire feed speed communication. Also some advanced welding
processes require and “arc sense lead” that provides a feedback welding voltage to the welding
power source, this is also included on this connector. The 15ft [4.6m] mating cable assembly is
supplied and is intended to connect to the contactor control circuit of the customers’ power
source. See page 43 for connection details.
REMOTE WATER COOLER START (OPTIONAL):
This connector is part of the optional Water Cooler Power Interface Kit and uses a 10
amp isolated relay to enable the customers’ water cooler to be turned on during welding
operations and off when not welding. 115v or 230v AC power supply to the water cooler (not
provided) is fed through the contacts of this normally open relay using the supplied “Y” plug and
receptacle cable assembly (not shown), thereby controlling the On/Off state of the water cooler.
The Water Cooler Manual/Auto Switch mentioned earlier in this manual, energizes the relay,
allowing the water cooler to be powered-up even when the PIPE KAT
®
is not welding.
NOTE: Units manufactured without the optional Water Cooler Power Interface Kit will not
have this connector.
