WARNINGS

  

CALIFORNIA PROPOSITION 65 WARNINGS

WARNING: 

Breathing diesel engine exhaust

exposes you to chemicals known to the State
of California to cause cancer and birth defects,

or other reproductive harm.

• Always start and operate the engine in a 

well-ventilated area.

• If in an exposed area, vent the exhaust to the outside.
• Do not modify or tamper with the exhaust system. 
• Do not idle the engine except as necessary.

WARNING: This product, when used for welding or
cutting, produces fumes or gases which contain
chemicals known to the State of California to cause
birth defects and, in some cases, cancer. (California
Health & Safety Code § 25249.5 

et seq.)

WARNING: Cancer and Reproductive Harm
www.P65warnings.ca.gov

ARC WELDING CAN BE HAZARDOUS. PROTECT
YOURSELF AND OTHERS FROM POSSIBLE SERIOUS
INJURY OR DEATH. KEEP CHILDREN AWAY. 
PACEMAKER WEARERS SHOULD CONSULT WITH
THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For
additional safety information, it is strongly recommended 
that you purchase a copy of “Safety in Welding & Cutting - 
ANSI Standard Z49.1” from the American Welding Society, 
P.O. Box 351040, Miami, Florida 33135 or CSA Standard 
W117.2-1974. A Free copy of “Arc Welding Safety” booklet 
E205 is available from the Lincoln Electric Company, 
22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWERED

EQUIPMENT.

   1.a. Turn the engine off before troubleshooting

and maintenance work unless the
maintenance work requires it to be running.

   1.b. Operate engines in open, well-ventilated areas or vent the engine

exhaust fumes outdoors.

   1.c. Do not add the fuel near an open flame welding

arc or when the engine is running. Stop the
engine and allow it to cool before refueling to
prevent spilled fuel from vaporizing on contact

with hot engine parts and igniting. Do not spill fuel when filling
tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.

   1.d.  Keep all equipment safety guards, covers 

and devices in position and in good repair.
Keep hands, hair, clothing and tools away 
from V-belts, gears, fans and all other 
moving parts when starting, operating or
repairing equipment.

   1.e. In some cases it may be necessary to remove safety guards to

perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.

   1.f.  Do not put your hands near the engine fan. Do not attempt to

override the governor or idler by pushing on the throttle control
rods while the engine is running.

   1.g. To prevent accidentally starting gasoline engines while turning

the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or  magneto wire
as appropriate.

   1.h. To avoid scalding, do not remove the radiator

pressure cap when the engine is 

hot.

ELECTRIC AND

MAGNETIC FIELDS MAY

BE DANGEROUS

   2.a. Electric current flowing through any conductor

causes localized Electric and Magnetic Fields (EMF). 
Welding current creates EMF fields around welding cables 
and welding machines

   2.b. EMF fields may interfere with some pacemakers, and 

welders having a pacemaker should consult their physician
before welding.

   2.c. Exposure to EMF fields in welding may have other health effects

which are now not known.

   2.d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Secure

them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode and work

cables. If the electrode cable is on your right side, the
work cable should also be on your right side.

2.d.4. Connect the work cable to the workpiece as close as pos-

sible to the area being welded.

2.d.5. Do not work next to welding power source.
