Hypertherm HT200LHF-200 Volt HySpeed - Manual (Page 29)

SPECIFICATIONS
2-2 HySpeed HT2000LHF
Instruction Manual
7
Remote Current Control Console
This unit contains a manually adjustable thumbwheel to set arc current only.
Initial Height Sensing - Optional
This unit, used with 2 inductive probes, is designed to automatically detect the workpiece surface and move the
torch to the pierce position. This system can be used for underwater cutting, cutting at the water line, or cutting
above water.
Timer/Counter – Optional
The timer/counter allows the operator to monitor the number of arc starts and the cumulative time that the arc is on
in hours. The arc starts can be reset.
Water Muffler – Optional
The water muffler for the LHF system is an option which greatly improves cutting safety and pollution control
capabilities. The water muffler can be used to cut above, below and at the water line. Refer to the Water Muffler
instruction manual 802050 for more detailed information. The water muffler cannot be used with the stainless steel
torch.
CommandTHC – Optional
The CommandTHC is an external torch height control and initial height sensing system designed for plasma cutting
applications on an x-y cutting table. Refer to the CommandTHC instruction manual 802780 for more detailed
information.
