unintentional contact.
D Wear dry, hole-free insulating gloves and body protection.
D Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground.
D Additional safety precautions are required when any of the follow-
ing electrically hazardous conditions are present: in damp locations
or while wearing wet clothing; on metal structures such as floors,
gratings, or scaffolds; when in cramped positions such as sitting,
kneeling, or lying; or when there is a high risk of unavoidable or ac-
cidental contact with the workpiece or ground. For these
conditions, see ANSI Z49.1 listed in Safety Standards. And, do not
work alone!
D Disconnect input power before installing or servicing this equip-
ment. Lockout/tagout input power according to OSHA 29 CFR

1-6. EMF Information
Considerations About Induction Heating And The Effects Of Low Fre-
quency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the
U.S. Congress, Office of Technology Assessment, Biological Effects of
Power Frequency Electric & Magnetic Fields Background Paper, OTA-
BP-E-53 (Washington, DC: U.S. Government Printing Office, May
1989): “. . . there is now a very large volume of scientific findings based
on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can in-
teract with, and produce changes in, biological systems. While most of
this work is of very high quality, the results are complex. Current scientif-
ic understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet allow
us to draw definite conclusions about questions of possible risk or to of-
fer clear science-based advice on strategies to minimize or avoid
potential risks.”
To reduce magnetic fields in the workplace, use the following proce-
dures:
1. Arrange output cable to one side and away from the operator.
2. Do not coil or drape output cable around the body.
3. Keep power source and cable as far away from the operator as
practical.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations. If
cleared by your doctor, then following the above procedures is recom-
mended.

4 Dual Output Cable Coolant Hose
Connect output cables to output #1 and
output #2 on power source.
Coolant hoses between output cables and
cooler must be connected in series for dual
output operation. Connect dual output
coolant hose between output cable #1 and
output cable #2 fittings by pushing coolant
hose fitting onto output cable fitting.
Connect quick-connect fitting on both
coolant hoses from cooler to remaining
output cable fittings.
To remove coolant hoses, grasp grey ring
on coolant hose fitting and pull away from
output cable fitting . Coolant hose fitting will
separate from output cable fitting.
. Fittings have spring loaded valves
inside that close when fitting is discon-
nected from an output cable fitting to
minimize coolant leaks.
. Heating cables must be the same
length: 30ft (9.1 m), 50 ft (15.2 m), 80ft
(24.2 m), or 140 ft (42.7 m).
. Total length of heating and extension
cables must not exceed 360 ft (110 m).
The extension cable is counted twice
the length because it has a supply and
return hose.
