Waterbed; Operation Of The Cnc Cut Controller - Eastwood VERSA-CUT Assembly And Operating Instructions Manual

• Feed and guide the cable until it reaches the bend in the drag chain.
• Traverse the torch full negative (left) on the X-Axis. The end of the
cable will now be after the bend in the drag chain. Feed through the
top and guide the end through the bottom.
• Once the end is out of the drag chain, you can feed with one hand and
pull with the other. Pull the cable fully through but leave some slack at
the top to avoid hose kinks or pulling on the torch.
• Cable tie the torch hose and Plasma Table cables to the X-Axis Gantry
to prevent risk of the cable getting caught in the rollers or gear rack
(FIG 25).
• The Plasma Torch is mounted successfully.

WATERBED

The Waterbed is used to reduce workpiece warpage, heat soak, sparks, slag spatter, and dust. Before filling with fluid, verify the table is level and if necessary,
shim under the feet or casters to correct.
INHALATION HAZARD!
DO NOT utilize additives which present inhalation and/or fire hazards when vaporized by the plasma arc. Examples: Anti-freeze,
sodium nitrite-based additives.
Plasma cutting without coolant can warp the Waterbed and will result in the cut area being extremely hot. Whenever possible cut with
coolant to prevent Waterbed damage and reduce burn risk.
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 Eastwood Versa-Cut 4' X 4' CNC Plasma Table, add 5 gallons [18.93 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.

OPERATION OF THE CNC CUT CONTROLLER

The following sections will sequentially detail each menu and option in the CNC Cut Controller with integrated Torch Height Controller (THC). The THC is capable
of automatically adjusting the height of the torch in real time to adapt to height variations in the material. The controller does this by monitoring the arc voltage,
which is the voltage of the plasma arc.
Higher arc voltage means the plasma arc is longer, lower arc voltage means it is shorter. With the Eastwood Versa-Cut 40 CNC Plasma Cutter, optimal arc voltage
lies between 98 - 115V typically. If arc voltage is too low the consumables will wear quicker because of slag blowback. If it is too high the cut will have an
excessive bevel, or the arc will not be sustainable.
