HT4100 Instruction Manual: Operation

Timer/Counter

The timer/counter is provided so that the number of arc starts and arc-on time can

be monitored. This unit is interfaced to the HT4100 Slave power supply.

Water Chiller

The water chiller for the HT4100 system is a refrigeration unit that is capable of

reducing the water coolant temperature well below ambient air and water supply

temperature. Having this capabililty greatly increases the life of the nozzle and

electrode. The water chiller is a three-phase power system that directly interfaces

with the HF console. See

Water Supply Requirements

in the Pre-Installation

section of this manual.

Initial Height Sensing (IHS) - Optional

This unit, used with two inductive probes, is designed to automatically detect the

workpiece surface and index the torch to the pierce position. This system can be

used for underwater, at the water line, or above-water applications. This unit inter-

connects with the Master power supply and the inductive probes, and requires an air

supply to operate.
