ROTATING PARTS MAY BE DANGEOUS:
• Use only compressed gas cylinders with the correct shield-
ing gas for the process that is to be used and ensure the
appropriate designed regulators are installed correctly. All
hoses, fittings, etc. should be suitable for the application
and should be in good working condition.
• Always keep cylinders in an upright position and securely
fasten these to an undercarriage or a fixed support.
• Cylinders should be located:
- Away from areas where they could be struck or be
subjected to physical damage.
- A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.
• Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
• Keep your head and face away from the cylinder valve
outlet when opening the cylinder valve.
• Valve protection caps should always be in place and hand
tightened except when the cylinder is in use or connected
for use.
ELECTRIC AND MAGNETIC FIELDS:
Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). When and
where possible, you should minimize exposure to EMF as
much as possible.
In order to minimize EMF, here are a few steps we recom-
mend you follow:
• Route the electrode and work cables together – Secure
these with tape wherever possible.
• All cables should be put away and kept at a safe distance
from the operator.
• Never coil the power cable around your body.
• Make sure the welding machine and power cable are as
far away from the operator as possible.
• Connect the work cable to the workpiece as close as
possible to the area being welded.
• People with heart pacemakers should keep a safe distance
away from the welding area.
The equipment complies with the Class A electromagnetic
compatibility which is intended for users in locations other
than residential locations where the electrical power is
provided by public low-voltage supply system.
• Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your assistants
from the arc rays.
• Protect nearby personnel with a suitable, non-flammable
screen and/or warn them not to watch the arc, hot spatter
or the metal.
WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION.
• Remove all fire hazards from the welding area. In the
event this is not possible, cover them with fire-retardent
material to prevent the welding sparks from generating a
fire. Important Reminder: Welding sparks and hot materials
can easily fall through small cracks and openings in adjacent
areas. Avoid welding near hydraulic lines and have a fire
extinguisher readily available.
• Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations.
• When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
• Do not heat, cut or weld tanks, drums or containers until
the proper steps have been taken to insure that such
procedures will not cause flammable or toxic vapors from
combusting substances inside. They can cause an explosion
even though they have been “cleaned”.
• Vent hollow castings or containers before heating, cutting
or welding. If you do not, this could lead to an explosion.
• Connect the earth lead cable to the work as close to the
welding area as practical. Earth Lead cables connected to
the building framework or other locations away from the
welding area increase the possibility of the welding current
passing through lifting chains, crane cables or other alter-
nate circuits. This can create fire hazards by overheating the
lifting cables until they fail.
