Flame cutting - debugging process,Contains three steps
Solution overview: Step1. Set the system to flame mode and parameters;
Step2. Manual test flame cutting;
Step 3. Start formal flame cutting ;
Detailed Description:
Step 1- Set the system to flame mode and parameters
Step 1-1 : Press the 【M】key on the keyboard at the cutting interface; change the cutting
mode to flame mode;【See photo below】:

Step 1-2 : Press the 【F4 Setups】key at the cutting interface→Into Parameter interface; →
Press the 【F2 Flame】; Need to change two parameter;
--Low Preheat Time 100.00S{This is the Preheat time of the flame. As the thickness of the
steel plate increases, the Preheat time increases.}
--Pierce 1 Time 01.50S{ This is the Pierce time of the flame cutting. As the thickness
of the steel plate increases, the Pierce time increases.}
Note: This time is based on the actual situation on site.

Step 2- Manual test flame cutting;{ We use oxygen+ acetylene as an example}
Step 2-1 : Connect acetylene and oxygen to the gas pipeline of the machine - red for gas pipeline
and blue for oxygen pipeline；
Change to 100S
Change to 01.50S

Note：The Oxygen pressure is adjusted to below max0.8Mpa; The acetylene pressure is adjusted
to below max0.8Mpa;Document attachment with flame cutting parameter table;
Step 2-2 : Ignition→Adjust the intensity of the flame
Press the 【Ignition】key on the keyboard;→Open preheated oxygen and acetylene valves,
Feel gas ejected by hand;→Ignition with a flame igniter
Note：When igniting, the oxygen output gas is too large and the flame is extinguished;
Control valve on
the machine

Adjust the intensity of the flame
Press the 【Cut】key on the keyboard;→Open Flame torch
regulating valve →Check the strength of the flame;→Press【IO
OFF】Test flame finish
The strength of the flame is adjusted according to the thickness
of the steel plate
Step 2-3 : Test flame cutting

Load G code or graphics→Press the green【start】button→Ignition with a flame igniter→
Waiting for Preheat→See redness steel reaches the molten state;→Press【Cut】key then Start flame
cutting;
Repeatedly adjust the intensity of the flame, the pressure of cutting oxygen, the cutting speed,
and the height of the cutting to optimize the cutting effect.
Step 3- Start formal flame cutting;
Load G code or graphics→Press the green【start】button→Ignition with a flame igniter→
Waiting for Preheat→See redness steel reaches the molten state;→Press【Cut】key then Start flame
cutting;
Note：If the preheat time is not modified, the system will automatically remember the last preheat
time, the next time the cutting machine runs the last preheat time and then automatically pierce-
cutting; However, it is also possible to press the 【Cut】button according to the preheat condition;
Then perforation-cutting
In the cutting process, you can adjust the cutting
speed according to home and end; adjust the
capacitance value of the CHC---control the height of
