Section 5 CONNECTIONS
5.1 Input Power
The rear panel of the CobraCooler™ has as standard a 120VAC type of
power outlet, which allows for the convenient connection of the CobraTig®
150 power supply.
Read the warning below prior to connecting ANY equipment to this power
outlet.
WARNING
THE REAR PANEL OUTLET WILL HAVE THE SAME POWER AS THE INPUT
INTO THE COOLER.
The input power cable is furnished with a standard 15A, 120VAC, three-prong
electrical connector. The power outlet is meant to be used with 120VAC, with
the CobraTig® 150 configured for 120VAC.
See Power Tapping section for instructions on changing configuration for
different input power values.
CAUTION
Adjust the corresponding input power taps in the CobraTig® 150 prior to connecting
to the power outlet on the CobraCooler™.
Otherwise serious electrical damage could occur to the CobraTig® 150.
5.2 Weldhead
The CobraCooler™ is designed be used with orbital weldheads supplied by
MK Products, Inc. The operational interface connection between the
CobraCooler™ and the CobraTig® 150 is easily performed.
The weldheads have a control cable with a 24 pin connector which plugs into
the CobraCooler™ rear panel. Coming from the rear panel of the
CobraCooler™ is a short control cable with a 24 pin connector, which plugs
into the rear panel of the CobraTig® 150 and is used to interface the
weldhead to the CobraTig® 150. It is through this interface that error signals
for LOW or NO coolant are transferred into the CobraTig® 150. Once one of
these errors is sensed, the CobraTig® 150 will display the appropriate fault
message, thus notifying the operator of a coolant-type fault.
The other connectors on the rear panel of the CobraCooler™ include the
coolant IN/OUT female quick-disconnect connectors. The male connectors
from either the Copperhead™ coolant hoses, the water hose assembly (P/N
005-0636) or the water-cooled extension cable (P/N 005-0635) can be
attached to this unit.
These coolant connectors are a double-end shut off valve type. This means,
if the cooler is turned on and there is nothing plugged into these connectors,
no fluid will flow out of the connector. Similarly, the connectors on the end of
the weldhead hose work in the same manner. No fluid will flow from the end
of the hose unless it is plugged into the cooler.
