5.3 CobraTig® 150 Latches
The CobraCooler™ easily attaches to the bottom of the CobraTig® 150 using
a four corner-mounted spring-locked latches. These latches are already
mounted to the four outside corners of the CobraCooler™. To the matching
corners of the CobraTig® 150, a screw and shoulder-washer are installed in
place of the existing sheet-metal screw.
Place the CobraTig® 150 on top of the CobraCooler™, so that all sides are
even and flush. Lift the finger handle of the latch and raise the spring up over
the shoulder-washer on the CobraTig® 150. Press down on the finger handle
until the locking spring engages.
Lift the finger handle to test the locking spring. Repeat process on all four
latches.
CAUTION
DO NOT ATTEMPT TO LIFT THE UNIT UNTIL ALL FOUR LATCHES ARE
LOCKED.
To disengage the CobraTig® 150 press on the locking spring and lift the
finger handle until the spring is released from the shoulder-washer.
Section 6 OPERATION
6.1 Coolant
CAUTION
COOLANT MUST BE ADDED PRIOR TO OPERATING.
From the top of the CobraCooler™, open the access panel towards the front
of the unit. Unscrew the fill plug and pour in the recommended mixture of
coolant (see TECHNICAL INFORMATION section for proper mix ratios).
DO NOT SPILL COOLANT INTO THE UNIT.
An electrical short may occur if coolant is spilled into the unit
The Coolant Level Indicator on the front panel of the CobraCooler™ shows
the operating level of coolant, without a weldhead. When a weldhead of
standard 25’ length is connected, and coolant is run through it, the coolant
level will lower. It is always best to read the coolant level when the unit is
operating and a weldhead is attached.
If the 25 ft. water-cooled extension cable is attached between the
CobraCooler™ and the weldhead, again the level of coolant will lower. Once
the extension cable and weldhead are attached, turn on the CobraCooler™
and read the coolant level. Add coolant as necessary.
It is recommended that all coolant be removed from the CobraCooler™ prior
to shipping. In order to drain the coolant, locate and remove the drain plug on
the bottom of the cooler. This will allow the coolant to drain from the reservoir
however some coolant may still remain in the internal pump and circulatory
tubing.
