CUTTING SPARKS CAN CAUSE INJURY, FIRE, OR EXPLOSION
 Remove all flammable materials from the welding area 
 Always have a charged fire extinguisher available in the cutting area 
 When not welding make sure the welding electrode is not grounded, this causes a heat build up and 
possible fire
 Avoid welding near hydraulic lines, fuel lines, electrical cords, air hoses, or welding guns and cables 
 Sparks and hot metal fly out from the arc when welding, wear approved safety glasses with side 
shields under approved helmets, wear proper body and hand protection, and wear flame resistant ear 
plugs to keep sparks from entering the ears 
CYLINDERS CAN EXPLODE IF DAMAGED
 Gas cylinders contain gas under very high pressure. If damaged they can result in that cylinder ex-
ploding. Gas cylinders are a major part of metalworking and must be treated with care.
 Protect gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs 
 Always keep cylinders in an upright position securely fastened to a fixed support 
 Valve protection caps should always be in place and hand tight except when the cylinder is in use 
 Keep all cylinders away from any cutting or electrical circuits 
 Never allow the arc from a welder to contact a cylinder 
 Never cut any type of pressurized cylinder, an explosion could result 
 Always turn your face away from the valve when opening the cylinder 
 Read and follow all instructions on compressed gas cylinders, associated equipment, and CGA pub-
lication P-1 listed in the Safety Standards before using
WELDING ARC CAN INJURE
 The heat from the welding arc is very intense and forceful and can burn through protective clothing
and pierce skin causing serious burns
 Check your protective clothing for holes, tears, or worn spots before welding. Replace any clothing
that is worn or damaged
 Do not hold or grip the material being welded too close to the weld pool 
 Always wear protective clothing when operating the welder, cover all exposed body areas 
 Turn off power source and unplug unit when dis-assembling electrode holder or ground clamp 
ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS
 Electric current used in welding create Electric and Magnetic Fields (EMF) 
 Magnetic fields can affect pacemakers and wearers should avoid proximity to EMF. Wearers need to 
contact their doctors before operating this type of equipment
 Exposure to EMF during operation of this equipment may have other health effects which are not
yet known
 Route the work and ground cables together and not around your body 
 Do not place your body between the work and ground cable. They both need to be on the same side 
of your body when operating
 Do not work next to the cutting or welding machine. Provide 3 feet of space between you and the
machine
ELECTRICALLY POWERED EQUIPMENT
 Disconnect power source or turn off the circuit breaker before working on any equipment 
 Only install equipment using the US National Electrical Code, all local codes, and the manufactur-
er’s recommendations
 Ground the equipment in accordance with the US National Electrical Code
