SAFETY INSTRUCTIONS AND WARNINGS

SECTION 1:

SAFETY INSTRUCTIONS AND WARNINGS

!

WARNING

SERIOUS INJURY OR DEATH may result if welding and cutting equipment is not properly installed, used and maintained.

Misuse of this equipment and other unsafe practices can be hazardous. The operator, supervisor, and helper must

read and understand the following safety warnings and instructions before installing or using any welding or cutting

equipment.

The welding and cutting process is used in many potentially dangerous environments such as elevated heights, areas

of limited ventilation, close quarters, around water, in hostile environments, etc., and it is important that the operator(s)

are aware of the dangers associated with working in these types of conditions. Be certain that the operator(s) are

trained in safe practices for environments in which they are expected to work and under competent supervision.

It is essential that the operator, supervisor and all other personnel in the work area are aware of the dangers of the

welding or cutting process. Training and proper supervision are important for a safe work place. Keep these instructions

for future use. Additional recommended safety and operating information is referenced in each section.

1.01 Welding Hazards

WARNING

electric shocK can cause injury or

death.

install and maintain equipment in

accordance With the national electrical

code (nfpa 70) and local codes. do not

service or repair equipment With poWer

on. do not operate equipment With

protective insulators or covers removed.

service or repair to equipment must be

done by a qualified repair technician, or

trained personnel only.

1.

Do not touch live electrical parts.

2.

Do not touch an electrode with bare skin and electrical

ground at the same time.

3. Always keep welding gloves dry and in good condition.

NOTE

Aluminized protective clothing can become part

of the electrical path.

4. Keep oxygen cylinders, chains, wire ropes, cranes, hoists,

and elevators away from any part of the electrical path.

5. All ground connections must be checked periodically

to determine that they are mechanically strong and

electrically adequate for the required current.

6. When engaged in alternating current, welding or cutting

under wet conditions or warm surroundings where

perspiration is a factor, the use of reliable automatic

controls for reducing the no-load voltage is recommended

to reduce shock hazard.

7. When the welding or cutting process requires values of

open circuit voltages in alternating current machines

higher than 80 volts, and direct current machines higher

than 100 volts, means must be provided to prevent the

operator from making accidental contact with the high

voltage by adequate insulation or other means.

8. When welding is to be suspended for any substantial

length of time, such as during lunch or overnight, all

electrodes should be removed from the electrode

holder and the electrode holder carefully located so that

accidental contact cannot occur.

9. The holder must be disconnected from the power source

when not in use.

10. Never immerse Mig-Guns, electrode holders, tig torches,

plasma torches, or electrodes in water.

WARNING

smoKe, fumes and gases can be dangerous

to your health.

11. Keep smoke, fumes, and gases from the breathing

area.

12. Fumes from the welding or cutting process are of various

types and strengths, depending on the kind of base metal

being worked on. To ensure your safety, do not breathe

these fumes.

13. Ventilation must be adequate to remove smoke, fumes,

and gases during the operation to protect operators and

other personnel in the area.

1-2

Quick fixed automation series torches

SM-QFTORCH

SAFETY INSTRUCTIONS AND WARNINGS

14. Vapors of chlorinated solvents can form the toxic gas

“Phosgene” when exposed to ultraviolet radiation from

an electric arc. All solvents, degreasers and potential

sources of these vapors must be removed from the work

area.

15. Fumes produced by welding or cutting, particularly in

conﬁned places, can cause discomfort and physical harm

if inhaled over an extended period of time.

16. Provide adequate ventilation in the welding or cutting

area. Use air-supplied respirators if ventilation is not

adequate to remove all fumes and gases. Never ventilate

with oxygen. Oxygen supports and vigorously accelerates

ﬁre.

WARNING

arc rays, hot slag, and sparKs can injure

eyes and burn sKin .

17. The welding and cutting processes produce extreme

localized heat and strong ultraviolet rays.

18. Never attempt to weld or cut without a welding helmet

with the proper lens. Ensure that the lens complies with

federal guidelines. A number 12 to 14 shade ﬁlter lens

provides the best protection against arc radiation. When

in a conﬁned area, prevent the reﬂected arc rays from

entering around the helmet.

19. Ensure all personnel in the work area are protected from

arc rays and sparks. Approved shielding curtains and

appropriate goggles should be used to provide protection

to staff in the surrounding area and operators of nearby

equipment.

20. Unprotected skin should also be covered from arc rays,

heat and molten metal. Always wear protective gloves

and clothing that does not allow skin to become exposed.

All pockets should be closed and cuffs sewn shut. Leather

aprons, sleeves, leggings, etc., should be worn for out-of-

position welding and cutting or for heavy operations using

large electrodes. High top work shoes provide adequate

protection from foot burns. For added protection use

leather spats.

21. Flammable hair preparations should not be used when

welding or cutting. Wear ear plugs to protect ears from

sparks.

22. Where the work area permits, the operator should be

enclosed in an individual booth painted with a ﬁnish of

low reﬂectivity such as zinc oxide. This is an important

factor for absorbing ultraviolet radiations, and lamp black.

The operator should be enclosed with non-combustible

screens similarly painted.

WARNING

Welding sparKs can cause fires and

eXplosions.

23. Causes of ﬁre and explosion are: combustibles reached by

the arc, ﬂame, ﬂying sparks, hot slag or heated material.

Remove combustibles from the work area and/or provide

a ﬁre watch.

24. Avoid oily or greasy clothing as sparks may ignite them.

Have a ﬁre extinguisher nearby, and know how to use

it.

25. Be alert to the danger of conduction or radiation. For

example, if welding or cutting is to be done on a metal

wall, partition, ceiling, or roof, precautions must be taken

to prevent ignition of combustibles on the other side.

26. Do not weld or cut containers that have held combustibles.

All hollow spaces, cavities, and containers should be

vented prior to welding or cutting to permit the escape

of air or gases. Purging with inert gas is recommended.

27. Never use oxygen in a welding torch. Use only inert gases

or inert gas mixes as required by the process. Use of

combustible compressed gases can cause explosions

resulting in personal injury or death. Arcing against any

compressed gas cylinder can cause cylinder damage or

explosion.

WARNING

noise can damage hearing.

28. Noise from the air carbon-arc process can damage

your hearing. Wear protective hearing devices to ensure

protection when noise levels exceed OSHA standards.

Adequate hearing protection devices must be worn by

operators and surrounding personnel to ensure personal

protection against noise.

Contact tips and nozzles should be cleaned frequently. Spatter

buildup may cause bridging between nozzle and tip. This

could cause electrical shorting between the nozzle and work

piece as well as restricting gas ﬂow.

Regularly inspect the conductor tube, torch and cable

assembly for abrasions, cuts, and undue wear. Replace or

repair any parts as needed.

The torch and conductor tube assemblies have o-rings for

seals. Lubrication of these o-rings should be done periodically

and periodical inspections should be made to ensure that the

o-rings do not de-grade, allowing water and/or shielding gas

leaks to occur. When removing the conductor tube from the

torch assembly, be sure the single o-ring located in the bottom

of the hole remains in place.
