Equipment Maintenance:
Faulty or improperly maintained
plasma cutting equipment results in poor cut-quality. It can
cause physical injury or death through fires or electrical shock.
a. Whenever possible, have a qualified person perform the
installation, troubleshooting and maintenance work on the
plasma cutter. Do not perform any electrical work on the
plasma cutter unless qualified to perform such work. Before
performing any maintenance work inside the plasma cutter,
disconnect the machine from the main electrical power
source.
b. Maintain plasma cutting cables, grounding wire and
connections, power cord and plasma cutter in safe working
order. Do not operate the plasma cutter or accessory
equipment in faulty condition. Keep the equipment away
from heat sources such as furnaces, wet conditions such as
water puddles, oil or grease, corrosive atmospheres and
inclement weather.
c. Keep all safety devices and cabinet covers in position and in
good repair. Use the plasma cutter for its intended purpose
and do not modify it in any manner. Unauthorized
maintenance repair will result in loss of warranty coverage.

AWS C5.1
b. Hot sparks or hot metals can fall into cracks in floors or wall
openings and cause a hidden smoldering fire. Make certain
that such openings are protected from hot sparks and metal.
Do not weld, cut or perform other work on used barrels,
drums, tanks or other containers until they have been
completely cleaned.
c. For fire protection, have fire-extinguishing equipment handy
for instant use. After completion of cutting, inspect the work
area for hazardous hot sparks or metal.
Electrical Shock: Voltages in excess of 110V can cause severe
burns or fatal shock. Severity of electrical shock is determined
by the path and amount of current through the body:
a. Never allow live metal parts to touch bare skin or wet
clothing. When standing on metal or welding in a damp area
you must be well insulated. Wear dry gloves and rubber-
soled shoes. Stand on a dry board or platform.
b. Always ground the plasma cutter by connecting a ground
wire between the machine and electrical ground. Do not use
worn, damaged or overloaded welding cables. Use well
maintained equipment.
c. When not cutting, turn off the equipment. Accidental
grounding can cause overheating and create a fire hazard.
Do not coil or loop the welding cable around parts of your
body. Be sure the ground cable is connected to the
workpiece as close to the cutting area as possible. Grounds
connected to the building framework or remote locations
increase the possibility of stray cutting currents.
d. Keep everything dry; clothing, work area, welding cables,
electrode holder, and cutting machine. Fix water leaks
immediately.
Ventilation: Cutting fumes, particularly in confined places,
can cause discomfort and physical harm if breathed over an
extended period of time:
a. Provide adequate ventilation by natural or mechanical
means. Do not cut on galvanized zinc, lead, beryllium, or
cadmium materials unless positive mechanical ventilation is
provided!
b. Do not cut in locations close to chlorinated hydrocarbon
vapors from degreasing or spraying operations. Heat or arc
rays react with solvent vapors forming phosgene, a highly
toxic gas.
c. If you develop momentary eye, nose or throat irritation
during cutting, ventilation is not adequate. Stop work and
take necessary steps to improve ventilation. Discontinue
cutting if physical discomfort persists.
d. Refer to AWS Standard Z49.1 in Item 6 for specific
ventilation recommendations.
