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.
1.2 Specifications
-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.

3 Signals summary of THC3T-02
3.1 Power supply
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.

the output of the very popular Hypertherm Powermax45® - The THC comes

standard equipped with a low voltage output of 1:50 divider. This ratio is the
most commonly used division in most major brands and there will most likely be
a plug for this connection on the outside of the cutter's unit.
