Hypertherm Safety and Compliance S-2
SAfetY
English
Touching live electrical parts can cause a fatal shock or severe burn.
• Operating the plasma system completes an electrical circuit
between the torch and the workpiece. The workpiece and anything
touching the workpiece are part of the electrical circuit.
• Never touch the torch body, workpiece or the water in a water table
when the plasma system is operating.
electric shock prevention
All Hypertherm plasma systems use high voltage in the
cutting process (200 to 400 VDC are common). take the
following precautions when operating this system:
• Wear insulated gloves and boots, and keep your body and clothing
dry.
• Do not stand, sit or lie on – or touch – any wet surface when using
the plasma system.
• Insulate yourself from work and ground using dry insulating mats or
covers big enough to prevent any physical contact with the work or
ground. If you must work in or near a damp area, use extreme caution.
• Provide a disconnect switch close to the power supply with properly
sized fuses. This switch allows the operator to turn off the power
supply quickly in an emergency situation.
• When using a water table, be sure that it is correctly connected to
earth ground.
eLeCtRIC SHoCK CAN KILL
• Install and ground this equipment according to the instruction
manual and in accordance with national and local codes.
• Inspect the input power cord frequently for damage or cracking
of the cover. Replace a damaged power cord immediately. bare
wiring can kill.
• Inspect and replace any worn or damaged torch leads.
• Do not pick up the workpiece, including the waste cutoff, while you
cut. Leave the workpiece in place or on the workbench with the
work cable attached during the cutting process.
• Before checking, cleaning or changing torch parts, disconnect the
main power or unplug the power supply.
• Never bypass or shortcut the safety interlocks.
• Before removing any power supply or system enclosure
cover, disconnect electrical input power. Wait 5 minutes after
disconnecting the main power to allow capacitors to discharge.
• Never operate the plasma system unless the power supply covers
are in place. Exposed power supply connections present a severe
electrical hazard.
• When making input connections, attach proper grounding conductor
first.
• Each Hypertherm plasma system is designed to be used only with
specific Hypertherm torches. Do not substitute other torches which
could overheat and present a safety hazard.
