Instruction Manual
Timer/Counter – Optional
The timer/counter monitors the number of arc starts and arc time on. This unit interfaces with the power supply.
Water Chiller – Optional
The water chiller for the HT4001 system is a refrigeration unit capable of reducing the water supply temperature
and increasing the water pressure to the RHF console. Reducing the water temperature greatly increases the life of
the nozzle and electrode. The water chiller requires a water supply and may also require a water softener. See
Water Supply Requirements in the Pre-Installation section of this manual. This three-phase power system
interfaces with the RHF console.
Refer also to Water Chiller Model D Instruction Manual (802410).
Initial Height Sensing (IHS) – Optional
This unit, used with two inductive probes, automatically detects the workpiece surface and indexes the torch to the
pierce position. This system is used for underwater, at the water line, or above-water applications. This unit
interfaces with the power supply and requires an air supply to operate.
H401 Slave Power Supply – Optional
This unit can function as a “slave” when paralleled with the HT4001 power supply, providing up to 750 amps of
current for the HT4001 system.
Refer also to H401 & H601 Instruction Manual IM41 (800410).
Water Muffler – Optional
The water muffler for the HT4001 system reduces radiated light, noise, and captures fumes and particles generated
during the cut process. The water muffler is used to cut both at water and below water levels. The water muffler
requires an air supply and a water supply.
Refer to the Water Muffler Instruction Manual (801730) for more detailed information.
