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.

!

WARNING

THIS PRODUCT CONTAINS CHEMICALS, INCLUDING LEAD, OR OTHERWISE PRODUCES CHEMICALS KNOWN

TO THE STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS AND OTHER REPRODUCTIVE HARM.

Wash hands after handling. (CALIFORNIA HEALTH & SAFETY CODE § 25249.5 ET SEQ.)

1.01 Welding Hazards

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 qualiﬁed and/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.

SAFETY INSTRUCTIONS AND WARNINGS

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.

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.

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.

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.

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.

INTRODUCTION AND DESCRIPTION

QRA Series Air-cooled Robotic Torch and Cable Assembly

The air-cooled QRA cable assembly uses QTR66 air-cooled conductor tubes. It has an air-cooled power cable rated at 600

amperes @ 60% duty cycle.

QRW Series Water-cooled Robotic Torch and Cable Assembly

The water-cooled QRW cable assembly uses QTRW63, QTRW64, or QTRW66 water-cooled conductor tubes. It is furnished

with a water-cooled power cable rated up to 600 amperes @ 100% duty cycle.

QRWA Series Water/ Air Robotic Torch and Cable Assembly

The QRWA cable assembly is a hybrid using QTRW63, QTRW64, or QTRW66 water-cooled conductor tubes but it utilizes an

air-cooled power cable assembly rated up to 600 amperes @ 80% duty cycle. If water ﬂow is interrupted, amperage rating

is decreased. This provides a torch that has water-cooling of the front consumables while providing a trouble free rugged

air-cooled cable assembly.

QRAS, QRWS, and QRWAS Robotic Nozzle-sensing Torch Cable Assembly

This series of torch and cable assemblies incorporates the same power cables and are rated at the same amperage rating

as the series mentioned above. The only difference is the torch block and the use of the QTRW64-ST series conductor tube

assembly.

A wide variety of conductor tube and front-end consumables are also offered. Contact your local welding distributor and/or

Tweco

CAUTION

When connecting the cablehoz connector, be

sure to apply a high strength thread locking

adhesive compound to the threads of the brass

block assembly before threading the cablehoz

connector onto the block. This connection must

be tightened to a torque of 30-35 inch/pounds.

Failure to tighten this connection properly could

cause the power cable to overheat.

Inch Switch / E-Stop Assembly

Wiring Schematic for E-Stop Cable

The QRA, QRW, & QRWA torches are furnished with a switch

housing mounted on the front case. This housing contains a

push button inch switch for feeding the welding wire through

the gun. Mounted next to the inch switch is a 3-pin socket

that will accept the E-stop cable from the robot deﬂection

mount.

Both the switch and socket are connected to a 6-wire cable

that runs along the inside of the inner protective jacket. The

end of this cable extends approximately 12” (304.8mm) out

of the rear case and comes standard with a 9-pin amp plug.

Adapter jumper cables are available to connect this cable to

most robots. See Table 4-1.

WATER-COOLED TORCH BODY AND CABLE ASSEMBLY

SECTION 5:

WATER-COOLED TORCH BODY AND CABLE ASSEMBLY

The water-cooled torch and cable assemblies incorporate water shut-off valves allowing the conductor tube to be removed

without shutting off the water supply. This reduces the chance of introducing moisture into the conductor tube and conduit.

Refer to Figure 5-1 & 5-2 showing the water shut-off valves on the QRW and QRWA Series Torch Body and Cable Assembly.

Figure 5-1: QRW Series Check Valves

VALVE

SPRING

HOSE NIPPLE

Figure 5-2: QRWA Series Check Valves

A water supply providing not less than 3/4 gallons/minute (2.84 liters/minute) water ﬂow must be used during operation. The

water supply should be installed to run when the power source is turned “on” if possible to avoid any damage to the torch

and cable assembly.

CAUTION

Operating a water-cooled torch and cable

assembly without water or restricted ﬂow will

result in damage to the cable assembly.

If the threaded power connection is removed from the QRW series block assembly make sure the component parts making up the

check valve remains inside of the block assembly. If the components are removed, make sure they are installed properly.

MAINTENANCE

SECTION 6:

MAINTENANCE

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 degrade, 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.
