Tweco 400 Ultra-Cut(October 2014) - Manual (Page 48)

ULTRA-CUT 100 XT/200 XT/300 XT/400 XT
3-22 INSTALLATION Manual 0-5264
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 HE400XT 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 cable from J70 on the power supply to J71 on the HE400XT after the Cooler and coolant lines have been
determined to be leak free.

Under low power plasma cutting the HE400XT 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.
