ADT-HC4500 CNC Flame/Plasma Controller

In case of manual pause in auto processing, when you press [F6] (breakpoint), the system will save the
current working track (current position of cutting gun) as a breakpoint automatically. This breakpoint is
saved permanently. When you restart the machine or re-enter the auto mode, as long as the current program is
not changed, you can press [F6] (Breakpoint) to restore based on the breakpoint. Once the breakpoint is
found, press [Start] and the system will continue the processing from the breakpoint. It is the same for the
plasma function.
1.3 Basic operations
1) I/O
Flame: Before processing, you can also select the strong electricity key manually to control
the ignition, acetylene, preheating oxygen, cutting oxygen, and cutting gun rising/falling/stop.
Note: when you press the ignition key, if the acetylene is not opened, it will open the acetylene
valve before switching on the ignition switch, and then switch off the ignition switch after an
ignition delay (see Parameter-Control-Ignition Delay). Press [Perforating] and it will perform
preheating perforating (see M07 Fixed Cycle of Preheating Perforating in section 4 of Chapter III).
Pressing [Main switch] is to close all IO outputs.
Plasma: You can use the arcing switch (Cutting Oxygen switch of flame cutting) to control
the arcing before processing and the system gives an arcing signal to the height-adjusting system.
If there is no height-adjusting system, the system will open the arcing switch; press [Perforate] to
starting arcing and perforating (See M07 arcing & perforating cycle in point 4, section 3); press
[Shut down] to shut all the output.
2) [F] and [F] allows you to increase or decrease the moving speed rate. In standby mode, you
can press and hold this key to increase or decrease the speed continuously. If in the process,
each press would increase or decrease the speed by 1.
3[Pgup/S] and [Pgdn/S] are composite keys. Press [Pgup/S] (or [Pgdn/S]) key, the cutting gun
will move upward (or downward) until it is released. It is to page up or down when editing.
