HF100 plasma Capacitve Height Controller

GENERAL DESCRIPTION

The cut quality for thermal cutting processes is affected by the amount of clearance between the torch tip and cutting material. Automatic control of the clearance span lets you make a smooth, quality cut at higher speeds with the least amount of dross.

HF100 lets you achieve and maintain the optimum amount of cut clearance and can provide the following economical advantages:

• Less preparation time because the HF100 controller quickly establishes the correct amount of clearance.
• Increased productivity as a result of higher cutting speeds.
• Optimum cut quality, reducing or eliminating the need for secondary processing.
• Identical cut quality on all machines.
• Fully automatic CNC machines.

The HF100 controller also provides the following advantages:

• Clearance is measured using a capacitive system allowing reproducible setting and maintenance of the once adjusted clearance.
• The lifter motor is controlled by a transistorized H-bridge Pulse Width Modulated (PWM) amplifier using armature voltage feedback and adjustable current limitation.
• For automation purposes, the integrated control logic offers an In-position signal that can also be used to detect cut-outs or collision with tip-ups.
• Automatic retract of the torch if the high-frequency cable is broken or damaged. You can override this feature when in Manual mode and continue cutting until the problem can be corrected.
• Automatic retract in Manual mode if a collision occurs with work piece or tip-up. The retract action stops when collision is cleared.
• Visual fault codes to aid in quick troubleshooting.
• The functions are implemented in a single control box that also contains the adjustment knobs for clearance and sensitivity.
• Upgrade compatible to HFA2 controller
