Tweco 300 XT Ultra-Cut Plasma Cutting System - Manual (Page 47)

ULTRA-CUT 300 XT
Manual 0-5274 INSTALLATION 3-23
CAUTION
Do NOT cross the coolant lines as this will not provide cooling for the XT™ plasma torch as designed
and void the warranty.
Attach and tighten all #6 JIC fittings with 11/16” (18mm) wrench. Do not overtighten as it will strip the fitting threads
and will cause a leak. Do not start the Ultra-Cut XT™ without coolant in the reservoir. An additional gallon (3.78l)
of coolant is required to compensate for the HE400 being attached to the system. Monitor the fluid level while filling
the Ultra-Cut XT. Do not allow the coolant reservoir level to drop below minimum.
Attach the J71 cable after the Cooler and coolant lines have been determined to be leak free.
Art # A-09624_AB
Under low power plasma cutting the HE400 may not come on. This is normal operation.
Periodically check obstructions in the radiator and remove them by vacuuming the fins. Do not use cleaners or
fluids to remove debris, they may affect the radiator integrity.
