SAFETY
4
Connect the work cable to the work as close to the welding area as practical. Work 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
alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
Gas cylinder safety precautions.
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, fittings,
etc. should be suitable for the application and maintained in good condition.
Always keep cylinders in an upright position securely chained to a fixed 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 source of heat, sparks or
flame.
Never allow the electrode
or any other electrically “hot” parts to touch a cylinder.
Keep your head and face away from the cylinder valve outlet when opening the valve.
Valve protection caps should always be securely in place except when the cylinder is in use
or connected for use in secured location.
1.3 Explanation of Electric and Magnetic Fields
Electric current flowing through any conductor causes localized Electro Magnetic Fields
(EMF). The effects of EMF are an ongoing discussion around the world. Up to now, no material
evidence has shown that EMF may have effects on health; however, the research on potential
damage due to EMF is still ongoing. Before any conclusion, all should minimize exposure to
EMF as much as possible by routing cables together (in cable cover if possible), keeping
cables a safe distance from the operator, being sure never to coil around your arms or body,
connecting the LINE power & ground (GRD) correctly and clamping the work cable to the
work-piece as close as possible to the weld area.
Warning: People with heart-pacemaker should be away from the welding operating area.
