ULTRA-CUT 400
3.17 HE400 COOLER
Used in series with the existing cooling system of the UltraCut series power supplies, the HE400 Cooler provides
necessary additional water cooling for the torch head when cutting at over 300amps. The HE400 operates indepen-
dently of the UltraCut pump and fans therefore it can start at any time.
!
WARNING
Do not disassemble the Cooler with the power applied or the coolant flowing. Dangerous 220 AC voltages
and high pressure liquid are present.
Locate the Cooler so that there is adequate ventilation in front of and behind the unit and do not place or stack
anything on top of the unit.
