1. Device information
1.1 Introduction
Compact THC3T-02 with Step/Dir output uses arc voltage to maintain a consistent
distance from the plate while the torch is cutting. This allows the system to maintain proper
torch height regardless of variations in the material, of flatness of the cutting bed.
Simplified block diagram:
The THC3T-02 package includes:
1 main board;
1 divider board;
1 potentiometer + cable.
1.2Specifications
-Using potentiometer to set height’s torch;
-Voltage divider and noise to obtain the raw signal from the plasma cutting;
-Using signal processing algorithms to derive the voltage stability of the plasma;
-Apply a algorithm to support smooth motion, this is a advantage of Compact
THC3T-02;
-Auto calib the arc voltage with any plasma cutter;
-Auto detect ARC OK;
-Integrated voltage divider 1:50;
-Control directly the Z axes driver with Step/Dir signal, give high performance
and more accuracy

A
Area for control
A001 to A050
Device will change to auto mode when
the arc voltage from:
[Voltage Set - Area for control] to
[Voltage Set + Area for control]
3
S
Sensitive
S100 to S800
This parameter determines the value
respond of Z axis motion.

P
Arc-voltage
P000 to P300
Display the arc voltage value from
plasma cutter.
5
d
Delay time
d001 to d099
The delay time to send ARC_OK from
0.1 to 10s: THC will sent ARC_OK
signal after this delay, the main purpose
is Z axis not move down at the first time
of cutting.
6
v
Run speed
v001 to v099
Change speed of motor from 0 to 100%
of max speed. This parameter only affect
in STEP/DIR version.
7
SW1
ON or OFF
Change the direction of Z motor.

3.2 Arc-voltage
When connecting directly, use the shortest possible cables for connecting the
plasma cutter with THC controller - it is recommended the THC controller to be mounted
directly at the plasma cutter.

While being a universal THC, accepting full raw arc voltage for most any plasma cutter
on the market, an exciting new standard feature of this unit is the addition of a 1:50
divider for an extremely fast, simple installation on most major brands. There will most
likely be a direct connection for this on the outside of the plasma cutter's unit. Please
refer to your plasma cutter owner's manual.
