Connecting Other Manufacturers' Plasma Cutters - Eastwood VERSA-CUT Assembly And Operating Instructions Manual

CONNECTING OTHER MANUFACTURERS' PLASMA CUTTERS

The Eastwood Versa-Cut 4' X 4' CNC Plasma Table may be used with other manufacturers' plasma cutters if they feature blowback (low frequency) start. The
following section describes the inputs required by the Plasma Table for control of the plasma cutter. Consult your plasma cutter manufacturer or a licensed elec-
trician on how to connect your plasma cutter to the Plasma Table.
ELECTRIC SHOCK CAN CAUSE INJURY!
Improper wiring practices can lead to electrical shock or start fires. Wiring should only be performed by a licensed electrician.
• High frequency start machines may damage and degrade the function of the Eastwood Versa-Cut 4' X 4' CNC Plasma Table.
Only use plasma cutters which have blowback (low frequency) start.
• Plasma cutter use with a CNC Plasma Table will subject the plasma cutter to extended periods of run time not seen while hand cutting. The
increased run time may result in machine overload and reduce the plasma cutter's lifespan if not intended for use with a CNC Plasma Table.
• Utilizing your plasma cutter with the CNC Plasma Table may violate your plasma cutter's warranty terms. If you are concerned about
invalidating your warranty, reach out to your plasma cutter's manufacturer for guidance. Eastwood is not responsible for warranty
violations or damage incurred to your plasma cutter.
• The included Plasma Cutter Control Cable [Q] provides the means for
connecting a plasma cutter. The two wires labelled START must be
connected to the trigger connection of the plasma cutter. These wires
have no polarity. It is a normally open circuit that closes when the
computer wants the plasma cutter to arc.
• For the Torch Height Controller to function, the two wires labelled ARC+
and ARC- need to receive the arc voltage (voltage between the ground
and the torch).
• The Torch Height Controller is factory configured to function with a 1:50
divided arc voltage ratio. If necessary, you can reconfigure it to function
with a 1:1 undivided arc voltage. Reconfiguring for undivided arc volt-
age is detailed below:
- First verify that the CNC Plasma Table is disconnected from
power and switched off.
- Remove the Control Box cover panel by unfastening the screw
at each corner (FIG 20).
- Switch the motherboard to 1:1 mode (FIG 21) with needle
nose pliers.
- Unplug the 1:50 connector, remove the wires from the connector,
and insert them into the 1:1 connection port. The 1:1 port is opened
by pressing the bottom tabs inward and they clamp on the wires
when released (FIG 21). Note that red is the positive (+) wire and
blue is the negative (-) wire. Correct polarity is important here.
- Reinstall the Control Box cover panel.
NOTE: In 1:1 mode the arc voltage input should not travel across a significant
resistive load, or the torch height control may not be able to function correctly.
• The wires labelled 0V and MOVE are not required.
• Once wiring has been completed, insert the Plasma Cutter Control
Cable [Q] connector to the Control Box and lock it (FIG 19). The Plasma
Table will now be able to control the plasma cutter.
