SAFETY PRECAUTIONS
WARNING
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.
•
Always connect the PYTHON ground-
ing terminal (located on the side of the
Case Back Assembly) to a good electrical
earth ground.
•
Turn the PYTHON Power Switch OFF
when connecting power cord to input
power.
___________________________________________
SELECT PROPER LOCATION
Place the PYTHON where clean cool air can freely cir-
culate in through the rear louvers and out through the
side/bottom openings. Dirt, dust or any foreign materi-
al 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 PYTHON. Oil in the air is a severe problem and
must be avoided. The supply pressure must be
between 80 and 120 psi. The flow rate is approximate-
ly 8.0 cfm (227 l/min.). Failure to observe these pre-
cautions could result in excessive operating tempera-
tures or damage to the torch.
STACKING
The PYTHON cannot be stacked.
INSTALLATION
LIFTING AND MOVING
Either the front or rear handles or both may be used to
lift or move the machine.
DO NOT use the pull handle on the optional undercar-
riage, if installed, to lift the machine. This handle is not
designed to support the full weight of the machine and
using it to lift the machine could cause personal injury
or damage to the machine.
TILTING
The PYTHON must be placed on a stable, level sur-
face so it will not topple over.
HIGH FREQUENCY INTERFERENCE
PROTECTION
The PYTHON employs a touch start mechanism for
arc initiation which eliminates high frequency emis-
sions 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 frequency generat-
ing machines are operating. By taking the following
steps, high frequency interference into the PYTHON
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 ground clamp isolated from other
work clamps that have high frequency.
(3) If the ground 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 recom-
mended.
Failure to observe these recommended installation
procedures may cause improper function of the
PYTHON or possibly even damage to the control sys-
tem or power supply components.
