SPECIFICATIONS

System Components

LHF Power Supply

The LHF power supply houses two 100-amp, 15 kHz choppers, the torch’s high-frequency starting circuit and an optional internal Torch Height Control (THC).

LHF Machine Torch

The LHF machine torch is liquid-cooled and capable of cutting most metals from gauge to 2-inch (50 mm) thickness and from gauge to 1-inch (25 mm) thickness for production cutting. To achieve consumable long life, all cuts

must begin and end on the plate surface.

LHF Gas Console

This unit houses metering and solenoid valves for shield and plasma gases, flow meters, pressure gauges for plasma gases, and a pressure gauge for the shield gas supply.

Argon-Hydrogen Manifold – Optional

This unit houses a flowmeter for argon-hydrogen, a metering valve, a plasma gas outlet switch and a plasma-off valve.

Digital Remote Voltage & Current Control Console

This unit includes LED displays that indicate the setpoints for volts and amperes prior to starting the arc. The displays then automatically display the actual values of the voltage and current while cutting. The digital remote has potentiometers to set and adjust the voltage and current.

Programmable Remote Voltage & Current Control Console

This unit includes LED displays that indicate the setpoints for volts and amperes prior to starting the arc. The displays then automatically display the actual values of the voltage and current while cutting. The programmable remote functions are controlled by the CNC.

Remote Current Control Console

This unit contains a manually adjustable thumbwheel to set arc current only.

Argon-Hydrogen......................................................120 psi +/- 10 psi (8.3 bar +/- 0.7 bar) at 105 scfh (2973 l/h)

Shield Gas Inlet Pressures and Flow Rates:

Air.........................................................................90 psi +/- 10 psi (6.2 bar +/- 0.7 bar) at 280 scfh (7929 l/h)

Carbon Dioxide ....................................................90 psi +/- 10 psi (6.2 bar +/- 0.7 bar) at 220 scfh (6230 l/h)

Nitrogen................................................................90 psi +/- 10 psi (6.2 bar +/- 0.7 bar) at 275 scfh (7787 l/h)

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. Refer to the CommandTHC Product Configuration Manual 802600 to order a CommandTHC system.
