Torch Lifter Requirements
The LHF system requires a high-quality, motorized torch lifter with sufficient travel to cover all cutting thickness
requirements. The lifter must provide
10 inches (254 mm) of vertical travel
. The unit should have a constant
speed of at least
20 ipm (508 mm/min)
with positive braking. A unit which drifts through the stop point is not
acceptable.
Optional Equipment
Water Muffler
Refer to Water Muffler instruction manual 802050. A power cable for the Water Muffler pump must be provided by
the customer. The pumps provided by Hypertherm take a three-phase input. Part numbers and corresponding
voltages are listed in the Water Muffler manual. Input current information is provided on the motor data plate.
Present pump systems all draw less than 20 amps and cable sizes should be selected accordingly.
The water muffler cannot be used with the stainless steel torch.
System Units Placement
• Position all required units prior to making electrical, gas and interface connections.
• Ground all external modules in the LHF system to earth.
• To prevent leaks in the system, tighten all gas and water connections to the following specifications:
Use 2 wrenches when tightening to prevent damage to the mating component.
