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-

facturer’s 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.

March 13, 2000 Revised Page 1

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.

9.With flatpartofpulleyfacingawayfrom the

engine fan, place the pulley onto the shutoff

valve screw and insert onto valve shaft shoul-

der. Be sure the pulley seats properly as it did

in Step 6.

10. Replace nut and lockwasher and secure

on valve screw.

11. Rotate torsion spring counterclockwise

untiltheverticalarm ofthespringlocksintothe

large hole in the end of the fuel shutoff arm.

12. Check pulley operation. If the pulleydoes

notreturn when rotated and released,then the

pulley and/or spring may not be installed prop-

erly. Recheck assembly positioning. (Refer to

Figure 3 for installation sequence.)

13. Reinstall fuel line removed in Step 7.

Assure clearance between pulley and fuel line

after installation. Fuel line may require some

slight reforming. (Disregard this step for MA-

5040D.)

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.

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 won’t change as solenoid cycles.

Disregard Steps 22 and 23, and then continue with Step 24 through the end to finish installation
