== SECTION 1- SAFETY RULES FOR OPERATION OF ARC WELDING MA CHINE mate
1-1. GENERAL
These rules apply to ac and dc welding generators, ac trans-
former and ac/dc welding machines, and dc transformer racti-
fier welding machines,
In arc-welding operations, where electricatly energized parts
are exposed, observe the following safety rules to insure max-
imum personal safety and protect nearby persons.
Failure to observe these safety precautions may expose not
only you, but fellow workers as well, to serious injuries, Once
these rules are learned and kept in mind, proceed with maxi-
mum assurance,
1-2. WELDING CABLES
DON'T overload cables, (Figure 1-1)
Figure 1-1. Don’t overload cables
NEVER use welding cables at currents in excess of their rated
capacity. It will cause overheating and rapid deterioration of
the insulation. It is also uneconomical, |
DON'T use worn or poorly connected cables. (Figure 1-2}
Figure 1-2. Don’t use worn or poorly connected cables
Inspect the cables frequently. Immediately repair all breaks
in the insulation with rubber and friction tapes. Tighten all
cable connections and adequately insulate any joints where a
connector may have an exposed conductive part. In addition
to the potential hazard to life, a hazard occurs when exposed
sections of cable come in contact with grounded metailic
objects, causing an arc, Unprotected eyes may be injured and
fire may result if combustible materials such as ail or grease
are in the vicinity, The efficiency and quality of welding will
be improved by elimination of these dangerous grounds, and
by keeping connections tight,
1-3. ELECTRODE HOLDER
DON'T use electrode holders with defective jaws. {Figure
1-3)
Keep the jaws of the electrode holder tight and the gripping
surfaces in good condition to provide close contact with the
electrodes, Defective jaws will permit the electrode to wob-
ble, making control of the welding operations difficult.
Figure 1-3. Don’t use Electrode Holder with defective jaws
DON'T use electrode holder with loose cablé connections.
Keep the connections of the electrode lead to the holder
tight at all times,
Use only fully insulated electrode holders (and without pro-
truding screwheads.)
Never touch two electrode holders from two separate welding
machines at the same time.
. CODE CONFORMANCE
The machine and its equipment must be installed and main-
tained in accordance with the National Electrical Code and
local requirements.
. PARALLEL CONNECTIONS
See diagrams in the instruction manual applying to the weld-
ing machine used.
. POWER DISCONNECT SWITCH
If the welding machine does not include a power disconnect
switch, install one at or near the machine.
. POLARITY SWITCH
DON'T operate the polarity switch under load.
The polarity switch (when supplied) is provided far changing
the electrode lead from positive (reverse polarity) to negative
{straight polarity). Never move it while under the load of a
welding current, Operate this switch only while the machine
is idling and the welding circuit is open. The potential dan-
gers of opening the circuit while carrying high current are:
1. An arc will form between the contact surfaces of the
switch and severely burn them,
2. The person throwing the switch may receive a severe burn
from this arcing.
. RANGE SWITCH
DON'T operate the range switch under load.
The range switch {when supplied} is provided for obtaining
required current settings, It must never be operated while the
machine is under the load of welding current. Operate the
range switch only while the machine is idling and the welding
circuit is open. The potential danger of switching the circuit
while carrying high current is the formation of an arc be-
tween the contact surface which will severely burn them,
Repeated occurrences of this arcing will eventually prevent
operation of the contacts,
. EXHAUST GASES
DON'T use gas engine units in confined spaces without vent-
ing the exhaust gases, (Figure 1-4)
H gasoline or other fuel driven welding machines are operated
indoors, provide means to pipe the exhaust gases to the out-
side air to avoid carbon monoxide poisoning.
OM-410 Page 1
Figure 1-4, Vent exhaust gases
1-10. POWER CIRCUIT GROUND
DON'F use welding machine without grounding frame or
case, (Figure 1-5)
1-11.
Page 2
Figure 1-5. Ground frame or case
Ground the ground cable of every power circuit to prevent
accidental shock by stray current. The potential danger is
that development of a stray current may give a fatal shock
should a person, for example, place one hand on the welding
machine and the other on the switch box, or other grounded
equipment. Do not ground to pipelines carrying gases or
flammable liquids and conduits carrying electrical conduc-
tors. Be sure conductors can safely carry the ground current.
When connecting the welding machine, properly ground the
machine frame or case.
CONTAINERS WHICH HELD COMBUSTIBLES
DON'T weld on containers which have held combustible or
flammable materials or materials which, when heated, give
off flammable or toxic vapors without proper cleaning, purg-
ing, or inerting.
Welding containers which have held flammable or combust-
ible materials may be extremely dangerous. To prevent a fire
or explosion of the container, follow the recommendations
of the American Welding Society Pamphlet A6.0 "Welding or
Cutting Containers Which Have Held Combustibles”,
DON'T depend on your eyes or nose to decide if it is safe to
weld on a closed container,
Find out what was in the container or use an explosimeter. A
very small amount of residual flammable gas or liquid can
cause a serious explosion.
NEVER use oxygen to ventilate a container.
When you know the container held a gas or нача which will
readily dissolve in water:
t. Flush out with water several times and then fill with
water as far as work permits, positioning container to
permit introduction of as much water as possible.
2. Before welding be sure there is a vent or opening to pro-
vide for release of air pressure,
1-12.
- When you know the: container held a gas or liquid which will
not readily dissolve in water:
1. Clean out thouroughly vith steam or a cleansing agent
and purge all air or inert with a gas such as carbon dioxide
Or nitrogen before repairing, Carbon dioxide is heavier
than air and will tend to remain in the container if the
opening is at the top,
2, Use steam to clean out light material,
3, Use a strong caustic soda solution to clean out heavy oils
or grease,
4. Be sure to purge all air or inert with a gas, such as nitro-
gen or carbon dioxide, no matter how well you have
cleaned, There may still be traces of oil, grease, or other
readily oxidizable material under the seams.
Be careful when cleaning witn steam or caustic soda wear
goggles and gloves.
DON'T clean where there is poor ventilation,
Ventilation is necessary to carry away harmful or explosive
vapors,
DON’T clean where there are open flames,
When scraping or hammering to remove heavy sludge or scale,
use a spark resistive tool and keep it wet to avoid sparks.
Keep your head and arms as far away from your work as
possible,
HOLLOW CASTINGS
DON'T weld on hollow {cored} castings that have not been
properly vented. The casting may explode, {Figure 1-6}
Figure 1-6. Don't weld on hollow (cored) castings
1-13. EXPLOSION HAZARDS
1-14
NEVER weld in or near explosive atmospheres. Such atmos-
pheres can be created by flammable gas leaks or by vapors
from fiammable liquids (gasoline, alcohol, etc.) or by com-
bustible dusts,
. VENTILATION
DON'T weld in confined spaces without adequate ventilation.
When welding in confined spaces, provide ventilation in
accordance with United States of American Standard 249.1,
1967. Always provide adequate ventilation by blowers, air
lines, or other acceptable means. Never use compressed ox-
yvgen. The depletion of the oxygen supply, the heat of weld-
ing, and the fumes given off may cause severe discomfort or a
serious illness,
When toxic fumes from lead or cadmium bearing materials or
any other substances are present in harmful concentrations,
always use an air supplied respirator.
1-15.
1-16.
1-17.
1-18.
SOLVENTS
Do not weld where chiorinated hydrocarbon vapors from de-
greasing, cleaning, or spraying may reach or ba drawn into air
surrounding the walding operation. The heat of the arc can
decompose solvent vapors to form phosgene, a highly toxic
gas and other irritating decomposition products,
Do not weld where ultraviolet light from the electric arc can
penetrate air containing even minute amounts of vapors from
solvents such as trichloroethylene or perchloroethytene, Ul-
traviolet light can decompose the vapors to form phosgene, a
highly toxic gas and other irritating products.
FIRE HAZARDS
DON'T weld near flammable or combustible materials.
Fires can be caused by the arc, by contact with the heated
metal, by slag, or sparks. Keep combustibles at least 35 feet
from the arc or suitably protected, If welding must be done
in a particular area, move the combustibles away. If they
cannot be moved, cover them completely with fire resistive
screens. Cover cracks or openings in floors or walls; sweep
floor free of combustibles and wet down, if wood, being sure
welder wears insulation shoe coverings. Avoid welding on par-
tition walls in contact with combustibles. Heated metal on
the other side of partition wall baing welded upon can ignite
combustibles in contact with the partition. Where other than
a minor fire might develop, have a fire watcher stand-by with
suitable fire extinguishing equipment for at least one-half
hour after the welding is completed.
ELECTRICAL SHOCK-VOL TAGE
OPEN power circuits before checking machines,
Before working on the wiring, switches, controls, étc., open
the power line disconnect switch. In most welding shops the
power supply used for arc welding machines is 230 or 460
volts, Open circuit voltages are usually tess than 100 volts and
welding or arc voltage drops are still tower. However, alt of
these voltages are capable of developing a harmful or fatal
current to the body.
DON'T touch electrically “hot” parts,
NEVER touch any exposed or non-insulated part of the
cables, cable connectors, clamps, electrode holders, elac-
trodes, or the power supply equipment to prevent harmful or
fatal electric shock or burns.
ELECTRICAL SHOCK-DAMPNESS
NEVER work in a damp area without suitable insulation a-
gainst shock. Keep hands, feet, and clothing dry at all times.
To prevent harmful body shocks, keep hands, feet and cloth-
ing dry. Never stand or lie in puddles of water, damp ground,
or against grounded metal when welding without suitable in-
sulation against shock. Always find a dry board or rubber
mat to stand on when water, moisture, or perspiration cannot
be avoided, Dampness between the body and an energized or
grounded metallic part lowers the resistance to the passage of
current to the body which may produce a harmful or fatal
shock, Salt in perspiration or sea water dangerously lowers
contact resistances,
Figure 1-7. Don't leave electrode in contact with grounded
metallic surface.
1-19. STARTING UNDER LOAD
DON'T leave an uninsulated electrode holder, or a “live”
1-20.
1-21.
ve
electrode on the table top or in contact with a grounded
metallic surface, {Figure 1-7}
When it is not in use, never place an electrode holder in
contact with the tabletop or other metallic surface in contact
with welding ground, Provide an insulated hook or holder for
the electrode holder. A potential danger is that a holder in
contact with the ground circuit provides a dead short circuit
on the welding machine. 1f the machine should be started up,
this short circuit would cause an excessive load on the ma-
chine and may damage the insulation.
FACE PROTECTION
DON'T use cracked or defective helmets or shields,
Keep the helmet, hand shields, or face shield in good condi-
tion. If cracks occur in the fibre material, replace the shield,
since the leakage of arc rays may cause serious burns.
EYE PROTECTION
NEVER under any circumstances, look at an electric arc
without eye protection.
-- |
Lo
Figure 1-8. Use eye protection at all times
Make sure that flash goggles are used under the weld-
ing helmet at all times, particularly while gas shielded-
arc welding.
in some type of arc welding, such as gas shielded-arc welding,
ultra-violet and infra-red radiation from the arc is particularly
intense and requires constant attention to avoid arc flashes to
the welder when striking an arc and to avoid exposure to
other welders, | |
NEVER strike an arc without ascertaining that nearby per-
sons either have the necessary protective equipment or are
looking in the opposite direction,
For welding operations in open areas, provide portable 7non-
reflecting screens to shield persons nearby from the rays of
the arc. Eye burns from the arc, through not generally per-
manent injuries, are exceedingly painful. Such burns fre-
quently referred to as flashes’, feel like hot sand in the eye.
If the eye is focused on the arc without filter-glass protec-
tion, infra-red radiation can cause retinal scarring and im-
paired vision. For eye burns consult your first aid station or
doctor.
NEVER use cracked, ill-fitting, or defective plates.
The filter glass plate provided in the helmets and shields must
be of reputable manufacture conforming to the latest Ameri-
can National Standards Institute, Standard 22.1. Replace
cracked or ill-hiting filter plates promptly.
NEVER use filter plates without a protecting cover glass,
OM-410 Page 3
1-22.
Keep a clean cover glass in front of the filter plate for the
protection thereof. Frequent renewal of these cover glasses is
necessary, since they become covered with spatter, reducing
vision.
CLOTHING
NEVER use poor, inadequate, or worn-out clothing. Wear
heavy shoes, tightly laced, Keep clothing dry.
. Proper and dry, oil-free clothing is essential for the weider's
1-23.
protection. Clothing must not only keep off the spatter and
molten particles, but must also cbstruct the rays of the arc
and, when necessary, insulate the body from harmful electri-
cal currents.
Wear [eather or asbestos gloves at all times to protect the
hands and wrists, Dark colored shirts are preferred to light
ones because light ones reflect arc rays to exposad parts of
the body. In the case of gas shielded-arc welding, light colors
are more reflective and may cause eve burns due to the in-
tense ultra-violet rays given off by the process, Avoid cotton
fabrics when gas shielded -arc welding, |
An arc burn on the skin resembles a sunburn, except that it is
usually more severe. Clothing can be made flame resistant by
treatment with a solution of 3/4 pound of sodium stannate in
1 gallon of water, then wrung out and dipped in a solution of
1/4 pound ammonium sulphate per gallon of water. Don’t
wash clothing so prepared in water, but dry clean.
When welding operations are to be performed in vertical and
overhead positions, leather sleevelets, aprons, and in some
cases leggings and ear plugs should be usad to prevent severe
burns from spatter and molten metal.
HOT METAL BURNS
NEVER pick up hot objects. (Figure 1-9)
Figure 1-9. Never pick up hot objects
NEVER pick up pieces of metal which have just been welded
or heated, or the stub ends of electrodes which have heen
discarded.
1-24. GRINDING AND CHIPPING
NEVER do any chipping or grinding without protective
goggles. (Figure 1-10)
Figure 1-10. Never do any chipping or grinding without
protective goggles.
Page 4
Whenever it is necessary 10 grind or chip metal, wear protec
tive goggles specifically designed for this purpose. Serious eye
Injuries may result from failure to wear protective goggles.
1-25. COMPRESSED GAS CYLINDERS
NEVER strike an arc on a compressed gas cylinder. Always
observe the following precautions in regards to compressed
gas cylinders:
~~ 1. Avoid accidental contact of the electrodes, electrode
- holder, or other electrically energized parts with a
compressed gas cylinder or any other pressure vessel.
Serious accidents or fires may result,
2. Use I.C.C, or D.O.T. cylinders. They are manufactured
and maintained in accordance with D.O.T, require-
ments and are safe so long as they are properly
handied. Don’t drop cylinders.
3, - identify gas content by the name marked on the cylin-
der, If the cylinder is unmarked, do not use it. Return
it to the supplier, Do not rely on a color code.
4. Never use a cylinder or its contents for other than
intended purposes.
5. Keep oil and grease away from oxygen cylinders and
cylinder valves, |
6. Keep cylinders away from exposure to sparks, hot
slag, open flame and all possible sources of ignition or
excessive heat,
7. - Be careful that cylinders are not placed so as to be-
come a part of an electrical circuit. Avoid third rails,
wires and electric welding circuits,
8. When transporting cylinders by crane, use cradle plat-
form or other suitable support,
9. Never lift the cylinders by slings, by the caps or by
electric magnets,
10. Never use cylinders as supports or rollers.
11. Never try to mix any gasas in a cylinder.
12. Never try to refill a cylinder,
13, Mark or tag empty cylinders “Empty” or “MT”.
14, Send “Emptys” back to the supplier promptiy. 15,
15. Keep "Emptys” and “Fulils” separate.
16. Never tampar with or alter cylinder numbers or other
markings. This is not only foolish but may be illegal.
17. Do not tamper with or change fittings on cylinders.
18. If valves cannot be opened by hand, do not use ham-
mer or wrench, Notify supplier.
19. Protect cylinder valves from bumps, falls, falling ob-
jects, and from weather, Keep them covered with
cylinder caps when moving cylinders,
20. Keep valves closed on empty cylinders,
21. See that your cylinders are clear of passageways and
active work areas and that they are secured against
falling,
22. If adapter is required between cylinder and regulator,
always use a standard adapter. These may be obtained
from your supplier. Where right and left hand threads
are used on adapter, use two wrenches to insure leak
proof connections.
23. Do not store cylinders in unventilated areas,

Use Table 3-1 as a guide for selecting correct cable size for
the anticipated maximum weld current which will be used.
Table 3-1 takes into account total cable length, which means
the length given in the table includes the electrode and work
cable. Example: If the electrode holder cable is 75 feet (23
meters) long and work cable 25 feet (8 meters) long, you
would select the size cable thatis recommended for 100 feet
(31 meters) at the maximum weld current y ou will be using.

LUBRICATION
This engine was shipped from the factory with its crankcase
filled with the correct amount and type of break-in oil unless
otherwise ordered. Check the cil level before attempting to
operate the engine. it should be up to the full mark on the
bayonet type indicator. Add a quality brand of detergent oil
if the oil level is low. See the oil selection chart, Table 9-1 in
Section 9,
IMPORTANT
New engines have very close clearance between their
moving parts. Thus, itis recommended that loading of
the engine be kept to a minimum during the first 10
hours of operation. Be sure to check the oil level
several times each day during the engine break-in per-
jod. This engine requires about 10 hours of running
time before it will be fully broken in.
After about 10 hours of running time, drain the break-in oil.
See the oil selection chart, Table 8-1, in Section 9 for correct
oil type and grade to use after the break-in cil is drained.

Never allow the fuel to drain on the engine, the gener-
ator, or other components. Arrange provisions for
catching the fue! when being drained and if the tank
must be drained frequently, install a valve and drain
line in the tank, When filling the fuel tank, do not fill
completely full. The reason being that the cold fuel
will expand due to engine heat and the outside air
when operating in a warm climate. If the tank is too
full, it will overflow causing a potential fire hazard,
Also, do not attempt to fill the fuel tank with the

| greatly reduced. I
STARTING THE ENGINE
IMPORTANT
Make sure all electrical equipment connected to the
115 or 230 volt receptacles are turned off before start-
ing the engine, The engine when starting has low speed
which causes low voltage at the output receptacie of
the generator. This could result in damage to electrical
| equipment. ]
1. Fill the fuel tank and check to ensure that oil level is
adequate.
2. Pull the Choke Control fully out. Lessor degrees of
choking may be required if the engine is warm.
о
Place the Throttle Control in the IDLE position.
La
. On models without electric start, give a quick steady pull
on the starter rope. For models with electric start, place
the Starter Switch in the START position,
5, Once the engine has started, slowly push the Choke Con-
trol inward.
©
Allow the engine to run for a few minutes before applying
a load. This is necessary to enable the engine to properly
warm up and ensure proper lubrication.
7. Place the Throttle Control in the desired position.
STOPPING THE ENGINE
1. Remove the load from the welding generator,
2. Place the Throttle Control in the IDLE position. Operate
the engine at this speed for 2 minutes; this will allow
internal engine temperature to equalize.
3. To stop the rope - started engine, depress the Stop Button
on the blower housing. On electric start models, place the
Starter Switch in the OFF position,

COLLECTOR RING BRUSHES
The brushes should be inspected periodically to ensure their
proper function, The brush life is very good under normal
conditions. If the generator has been operating tn an ex-
tremely dusty or dirty location, a close check of the brushes
for freedom of movement and cleaniiness should be made
weekly, Under normal use the commutator and slip rings will
discolor to a dark brown, If it should become necessary to
clean the slip rings or commutator, use a 3/0 or finer sand-
paper followed by a crocus cloth. Never use emery cloth as
part of the emery will embed itself into the exciter or col-
lector rings and in turn destroy the carbon brushes.
