Read entire Installation Section before installing the TOMA-
HAWK™ 1000 .
SAFETY PRECAUTIONS
ELECTRIC SHOCK CAN
KILL.
•
Only qualified personnel
should install this machine.
•
Turn the input power OFF
at the disconnect switch or
fuse box and discharge input capacitors before
working inside the equipment.
•
Do not touch electrically hot parts.
•
Turn the TOMAHAWK™ 1000 Power Switch OFF
when connecting power cord to input power.
-------------------------------------------------------------------------------------
SELECT PROPER LOCATION
Place the TOMAHAWK™ 1000 where clean cool air can freely
circulate in and out of the louvers. Dirt, dust or any foreign
material that can be drawn into the machine should be kept at a
minimum. Failure to observe these precautions can result in
excessive operating temperatures and nuisance shutdown of
the machine.
A source of clean, dry air or nitrogen must be supplied to the
TOMAHAWK™ 1000. Oil in the air is a severe problem and
must be avoided. The supply pressure must be between 80 and
110 psi. The flow rate is approximately 4.0 cfm (113 l/min.).
Failure to observe these precautions could result in excessive
operating temperatures or damage to the torch.
STACKING
The TOMAHAWK™ 1000 cannot be stacked.
TILTING
The TOMAHAWK™ 1000 must be placed on a stable, level sur-
face so it will not topple over.
HIGH FREQUENCY INTERFERENCE PRO-
TECTION
The TOMAHAWK™ 1000 employs a touch start mechanism for
arc initiation which eliminates high frequency emissions from
the machine as compared with spark gap and solid state type
high frequency generators. Keep in mind, though, that these
machines may be used in an environment where other high fre-
quency generating machines are operating. By taking the fol-
lowing steps, high frequency interference into the TOMA-
HAWK™ 1000 can be minimized
(1) Make sure the power supply chassis is connected to a
good earth ground. The work terminal ground does NOT
ground the machine frame.
(2) Keep the work clamp isolated from other work clamps that
have high frequency.
(3) If the work clamp cannot be isolated, then keep the clamp
as far as possible from other work clamp connections.
(4) When the machine is enclosed in a metal building, several
good earth driven electrical grounds around the periphery
of the building are recommended.
Failure to observe these recommended installation procedures
may cause improper function of the TOMAHAWK™ 1000 or
possibly even damage to the control system or power supply
components.
INPUT ELECTRICAL CONNECTIONS
The TOMAHAWK™ 1000 is rated for 208VAC through 575VAC
input voltages. Before installing the machine, check that input
supply voltage, phase, and frequency are the same as the
machine's voltage, phase, and frequency as specified on the
machine's rating plate.
• The TOMAHAWK™ 1000 should be connected only by a
qualified electrician. Installation should be made in accor-
dance with local codes.
INPUT PLUG INSTALLATION
POWER
CORD
CONNECTION
A power cord is provided and wired into the machine. Follow the
power cord connection instructions.
Single Phase Input
Connect green lead to ground per National Electrical Code.
Connect black and red leads to power.
Wrap white lead with tape to provide 600V insulation.
Three Phase Input
Connect green lead to ground per National Electric Code.
Connect black, red and white leads to power.
•
Failure to wire as instructed may cause personal injury or
damage to equipment. To be installed or checked by an
electrician or qualified person only.
------------------------------------------------------------------------------------
In all cases, the green or green/yellow grounding wire must be
connected to the grounding pin of the plug, usually identified by
a green screw.
