ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS
Instruction 830001
May 8, 1996 2-1
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The
flying sparks and hot metal, weld spatter, hot work-
piece, and hot equipment cancause fires and burns.
Accidental contact of electrode or welding wire to
metal objects can cause sparks, overheating, or fire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material.
3. Remove all flammables within 35 ft (10.7 m) of the welding arc.
If this is not possible, tightly cover them with approved covers.
4. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or partition
can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding area as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11. Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
FLYING SPARKS AND HOT METAL can
cause injury.
Chipping and grinding cause flying metal. As welds
cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side shields rec-
ommended.
2. Wear proper body protection to protect skin.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pres-
sure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding process,
be sure to treat them carefully.
1. Protectcompressedgascylindersfromexcessiveheat,mechani-
cal shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining
themtoastationarysupportorequipmentcylinderracktoprevent
falling or tipping.
3. Keep cylinders awayfrom anywelding orother electricalcircuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
6. Turn face away from valve outlet when opening cylinder valve.
7. Keep protective cap in place over valve except when cylinder is
in use or connected for use.
8. Readand follow instructions on compressed gas cylinders, asso-
ciated equipment, and CGA publication P-1 listed in Safety
Standards.
ENGINES can be hazardous.
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1. Use equipment outside in open, well-ventilated areas.
2. If used in a closed area, vent engine exhaust outside and away
from any building air intakes.
FUMES AND GASES can be hazardous
to your health.
Weldingproducesfumesandgases.Breathingthese
fumes and gases can be hazardous to your health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the manu-
facturers instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Shielding gases used for
welding can displace air causing injury or death. Be sure the
breathing air is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and raysof the arc canreact with vaporsto
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from the
weld area, the area is well ventilated, and if necessary, while
wearing an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if welded.

NOTE: Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the U.S. Congress, Office of Technology Assessment,
Biological Effects
of Power Frequency Electric & Magnetic Fields Background Paper, OTA-BP-E-63 (Washington, DC: U.S. Government Printing Office, May
1989): ... there is now a very large volume of scientific findings based on experiments at the cellular level and from studies with animals and
people which clearly establish that low frequency magnetic fields can interact with, and produce changes in, biological systems. While most of
this work is of very high quality, the results are complex. Current scientific understanding does not yet allow us to interpret the evidence in a
single coherent framework. Even more frustrating, it does not yet allow us to draw definite conclusions about questions of possible risk or to
offer clear science-based advice on strategies to minimize or avoid potential risks.
To reduce magnetic fields in the workplace, use the following procedures:
About Pacemakers:
The above procedures are among those also normally recommended for pacemaker wearers. Consult your doctor for complete information.
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around the body.
4. Keep welding power source and cables as far away from body as
practical.

5. Remove pivot (8) from fuel shutoff arm and attach arm to the fuel shutoff linkage (pulley) supplied in kit.
Mount using the same hardware that attached the pivot to the arm. Align the pulley center hole and arm slot.
Put the screw into the short side of the arm. The arm should be parallel to the face of the pulley (see Figure
2).
6. Test fit fuel shutoff pulley on the shutoff valve to be sure it seats properly on the valve shaft shoulders.
The flat part of the pulley should face away from theengine fan. (If it does not seat properly, the shutoff valve
will not function correctly.)
7. On models MA-4030D and MA-4535D (3-cylinder engine), the fuel line may need to be removed from
the filter at the fan end of the injection pump in order to complete Steps 8 to 12. (See Note, Step 13.) On
some older 3-cylinder engines,it may be necessary to use a fileto remove a web of material located between
the stop post and the shutoff valve post. File web down until it is flush with pump body. Refer to Figure 3.
8. Place torsion spring supplied in kit over shutoff valve post with straight leg down and positioned between
the valve post and the stop post.

OPTIONAL ENGINE PROTECTION LINKAGE FOR 3.152 PERKINS ENGINES
These instructions need to be followed when installing the optional rigid linkage specifically designed for
the Perkins 3.152 powered units only (Mega-Arc 4030D or the Mega-Arc 4535D). This linkage is optional for
use,and may providean easierinstallationthan the standard flexiblelinkage also included with this kit. Either
linkage will give adequate serviceand the choice of whichto use is up to the installer.In either case, the rigid
linkage assembly will work only with the 3.152 engines and if installing a kit on a 4.236 engine (Mega-Arc
5040D) you must use the flexible cable linkage.
Follow the directions in the original instruction sheet, Steps 1 through 4, disregard Steps 5 through 13,
perform Steps 14 through 21, then use the following addendum instructions and photo to properly install the
rigid linkage parts.
Remount fuel shutoff arm removed inStep 4 (from original instructions), using nut and lockwasher . Assure
the slot of the arm is aligned with the shoulder of the shaft. Attach upper linkage (with formed offset) from
this kit to the free end of the tension spring on solenoid. Spring should lie on top of the linkage and a flat
washer should be placed against the loop end of spring. Assemble with 1/4-20 x 1/2 screw and with the Keps
lock nut against flat washer.
Place lower linkage pivot pin into hole on the speed control arm. Assemble two halves of linkage using hex
head #8 screws, lockwashers, and brass flat washers. Lower linkage should be below the upper linkage.

arm placing 3/64-diameter cotter pin into hole in pivot. Bend cotter pin around pivot to assure clearance of
other components.
To fine tune linkage length, fully compress solenoid plunger, making sure the plunger is bottomed in the
solenoid. Adjust linkage length using the #8 hex screws or the 1/4 nuts on the solenoid plunger shaft, or both.
Length is correct when the fuel shutdown arm is against the stop closest to the solenoid and the tension
spring is stretched 1/16 to 1/8 inch with the solenoid plunger bottomed out. Tighten fully the #8 hex screw to
assure linkage length wont change as solenoid cycles.
Disregard Steps 22 and 23, and then continue with Step 24 through the end to finish installation
