SAFETY
4
Rotating parts may be dangerous.
Use only compressed gas cylinders containing the correct shielding gas for the process used
and properly operating regulators designed for the gas and pressure used. All hoses, ttings,
etc. should be suitable for the application and maintained in good condition.
Always keep cylinders in an upright position securely chained to an undercarriage or xed
support.
Cylinders should be located:
-
Away from areas where they may be struck or subjected to physical damage.
-
A safe distance from arc welding or cutting operations and any other source of heat,
sparks, or ame.
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 tight except when the cylinder is in
use or connected for use.
§1.3 The knowledge of Electric and Magnetic Fields
Electric current owing through any conductor causes localized Electric and Magnetic
Fields (EMF). The discussion on the e ect of EMF is ongoing all the world. Up to now, no
material evidences show that EMF may have e ects on health. However, the research on
damage of EMF is still ongoing. Before any conclusion, we should minimize exposure to EMF as
few as possible.
In order to minimize EMF, we should use the following procedures:
Route the electrode and work cables together – Secure them with tape when possible.
All cables should be put away and far from the operator.
Never coil the power cable around your body.
Make sure welding machine and power cable to be far away from the operator as far as
possible according to the actual circumstance.
Connect the work cable to the workpiece as close as possible to the area being welded.
The people with heart-pacemaker should be away from the welding area.
