Basic Functions

：

A

、

Automatic Initial Height Sensing (IHS)

：

Torch Retaining Cap HIS and Proximity Switch HIS 

(NPN and PNP), 

Proximity Switch HIS is backup for Torch Retaining Cap HIS for cutting dirty/rusty 

workpiece, needing the Anti-Collision Fixture(breakaway kit).

、

Torch Anti-Collision Function: 

We designed Touch-up circuit for Anti-collision function. No matter it is on Auto 

Control Model or Manual Control Model, when torch head touches the workpiece, 

THC would automatically lift torch up to HIS height, 

so with HCA1002, even in 

Manual Control Model, user doesn’t need to worry about torch head crashing. 

C

、

Freeze Auto Height Control on Corner Signal 

It can recognize Corner Signal From CNC and Freeze Auto Control Model on 

receiving this signal, and we have a unique design to backup this function. 

We set 30V 

(adjustable) as Turning Point according to our years practice. 

When the Actual Arc 

Voltage is higher than set Arc Voltage over 30V, THC Auto Control Mode freezes to 

avoid torch head diving, until it goes back to 30V range. This Over Voltage protection 

can avoid torch diving on voltage spikes (Corner Tuning, Kerf Crossing) Effectively.

、

Lifter Torch Up on HIS Disabled Status

On HIS disabled status, Jogging torch head down until it reaches workpiece, 

when Arc Starts, Torch head would lift up automatically to the Set Height set via the button 

SET-HIS. 

E

、

  Lifter Torch Up on TURN ON or ARC Off

When  CNC  is  TURN  ON  or  Plasma  Arc Off, THC would lift torch up for 2 

seconds

, please notice this Function during commissioning, avoiding the possible 

damage of limit switch or lift device.

Set Pierce Delay Time 

                Set Button Set-PIERE (set Pierce delay time), to delay output this signal, it is a
