OPERATION OF THE CNC CUT CONTROLLER
The following sections will sequentially detail each menu and option in the CNC Cut Controller, then Torch Height Controller.
To get an abbreviated version and start cutting quickly go to page 31 for the quick start guides.
PHYSICAL CONTROLS
The CNC Cut Controller has a color 7” LCD display
and 45 keys. The key switch and emergency stop
(FIG 4) control power to both the cut control-
ler and the Torch height controller. Pressing the
emergency stop button will immediately cut
power to the controllers, halting cutting and
movement operations, until it is rotated clockwise
to restore power.
The main control clusters for the CNC Cut
Controller are highlighted in (FIG 9).
ALCD screen used to monitor and navigate
the Controller.
BMain function keys used for accessing menus
and altering settings quickly. The function of
these keys will be shown in a bar at the
bottom of the LCD screen. Key F8, along with
Enter is commonly used as a key to confirm a
change or select continue.
CUSB drive connection for importing and
exporting files.
DManual controls for cutting functions. In configuration as a plasma cutter, only the Plasma button is utilized to toggle start/stop manual cutting.
EGreen arrow movement controls manually traverse the plasma Torch and are used in some menu navigation. The Torch height can be manually moved by the
Sand Skeys. F+ HOME and F- END can be used to change cut speed quickly before cutting. ESC is the common key for returning back to the previous
menu, reverting a change, or canceling a cut in progress.
FMachine movement/program controls. To start a program, first START is pressed then Enter to confirm. STOP will pause a program; START will resume it.
GQuick access settings used to alter key settings without having to go into the settings menus. Key Enter, along with F8 is commonly used as a key to
confirm a change or select continue.
HNumber and letter keypad is mostly used for setting entry and file naming. Shift is a modifier key that can be used in conjunction with the other letter/number
combo keys to input the letter.
WATERBED
The Waterbed is used to reduce heat soak, sparks, slag spatter, and dust. If your machine is not utilized frequently you may find it easier to leave the Waterbed
dry and simply cut without any coolant. This is perfectly fine and causes no additional harm to the Table or Plasma Cutter. However, the workpieces will be
extremely hot after cutting. Additional downsides to air cooled cutting are far more dust and flying sparks, and increased warpage.
The Waterbed can be filled with tap water, however it can contain many minerals and impurities which may affect performance. Eastwood strongly recommends
adding the Eastwood Plasma Cutting Fluid, #33863 1 Gal. or #33864 5 Gal., to the water in a 5:1 solution to eliminate corrosion and fungal build up. This additive
also eliminates risk of explosion when cutting aluminum sheet by preventing the creation of hydrogen. Many other plasma fluid additives are hazardous, toxic, or
carcinogenic.
Extensive in-house, R&D research was done to make sure the Eastwood Plasma Cutting Fluid is completely safe for usage and fully effective. For the Waterbed
on the 4’ x 4’ Table, add 10 gallons [37.85 liters] and then fill the rest of the table with water to get the right solution. As the fluid evaporates out over time, it can
be topped off with water. The solution concentration will remain effective until approximately 15 gallons [56.75 liters] of water have been added to replace
evaporated water. At this point the solution should be replaced. Alternatively, as water evaporates, mixed solution can be added to keep the solution effective.
When filling the waterbed keep in mind that it is most effective when the water level is high. Plasma Cutting is not affected by the water level and can even be
done submerged for maximum cooling.
INHALATION HAZARD!
DO NOT utilize additives which present inhalation and/or fire hazards when vaporized by the plasma arc.
Example: Anti-freeze, sodium nitrite-based additives.
