FOR ENGINE
powered equipment.

7.a. Turn the engine off before troubleshooting and maintenance

work unless the maintenance work requires it to be running.

---------------------------------------------------------------------------------------

7.b. Operate engines in open, well-ventilated

areas or vent the engine exhaust fumes out-
doors.

---------------------------------------------------------------------------------------

FOR ELECTRICALLY
powered equipment.

6.a. Turn off input power using the disconnect

switch at the fuse box before working on
the equipment.

6.b. Install equipment in accordance with the U.S. National

Electrical Code, all local codes and the manufacturer’s rec-
ommendations.

6.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

CYLINDER may explode
if damaged.

5.a. Use only compressed gas cylinders contain-

ing 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.

5.b. Always keep cylinders in an upright position securely

chained to an undercarriage or fixed support.

5.c. 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 other source of heat, sparks, or flame.

5.d. Never allow the electrode, electrode holder or any other

electrically “hot” parts to touch a cylinder.

5.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

5.f. Valve protection caps should always be in place and hand

tight except when the cylinder is in use or connected for
use.

5.g. Read and follow the instructions on compressed gas cylin-

ders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,”available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.

7.c.Do not add the fuel near an open flame weld-

ing arc or when the engine is running. Stop
the engine and allow it to cool before refuel-
ing 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.

---------------------------------------------------------------------------------------

7.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 mov-
ing parts when starting, operating or repair-
ing equipment.

7.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.

7.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.

7.g. To prevent accidentally starting gasoline engines while turn-

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

---------------------------------------------------------------------------------------

7.h. To avoid scalding, do not remove the radia-

tor pressure cap when the engine is hot.

ELECTRIC AND MAGNETIC
FIELDS
may be dangerous

8.a. Electric current flowing through any con-

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

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

welders having a pacemaker should consult their physician
before welding.

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

effects which are now not known.

8d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

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

them with tape when possible.

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

8.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.

8.d.4. Connect the work cable to the workpiece as close as

possible to the area being welded.

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

4.f. Sparks and spatter are thrown from the welding arc. Wear oil

free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a weld-
ing area.

4.g. 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.

4.h. Also see item 7c.
