Menu Operation
When torch is not working, parameters can be changed by panel button. Users
can flexibly change speed, working way and so on.

）
Spin button operation
The panel has three spin buttons; it can change arc voltage, initial height and
delay time for piercing.

High and low level control
Input switch can choose using low level or high level, it can suit complicated
applied environment. The default level is low. Also it can be changed by menu.

The function of avoiding collision
When torch is working, if the lower arc voltage setting value(or nozzle loss)
lead to torch collide work piece, THC can send rise signal , it can avoid torch collide
work piece continually and damage work piece. When collision happen in a
condition which torch is working, if collide have happened several times, we can
make numerical control stop work. Before equipment leave factory, if collision is
happening, CNC will make torch stop work. If user do not make collision input
signal connect with CNC, so when collision happen a condition which torch is
working, CNC cannot receive the collision signal, it make torch continue to work.
Whatever numerical control system whether have stopped torch, when collision
happened, THC can promote torch height automatically until down height initially.
When torch is not working, if torch collide steel plate, torch will automatic
promote a height named urgency collision rise spear height(in general, this height is
higher than down height, and this parameter can be change).

Intelligent arc voltage adjust
When intelligent arc voltage adjust is been use and torch is working, if torch
collide continuously steel plate twice, arc voltage can increase automatically a value
which we have set (this parameter can be change, it is 5V that we set), for example,
if arc voltage setting value is 110V, after torch collide continuously steel plate twice,
arc voltage setting value increase automatically 5V, arc voltage setting value is 115V
now, it can promote torch height to avoid collide work piece when torch is working.

Dynamic pierce function
During torch is working, if set-pierce have delay, torch can promote a height
when arc start work at the moment. Before delay time of piercing have
accomplished, torch can descend a height which it is the same with promoting
height. It can be named dynamic pierce function similarly. When piercing is
working, torch need promote a height, it can avoid dress get into torch head. If
dynamic pierce lifting times that we set is 0, torch cannot promote when arc start is
working.
