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.
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.
1.01 Welding Hazards

SM-QRC-2000
SAFETY INSTRUCTIONS AND WARNINGS
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 w
eld 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.
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.
WARNING
ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE
EYES AND BURN SKIN .
17. The welding and cutting processes produces 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.

INSTALLATION AND OPERATION
3.03 Air Supply, Connections, and
Lubrication Requirements
The air supply for the QRC
TM
-2000 nozzle cleaning station
should be filtered, unlubricated air. This unit requires 80-
100 PSI @ 8 CFM (5.5 – 6.8 BAR @ 225 LPM). The air
supply line should be a minimum of 1/4” I.D. with a male
1/4” NPT connection to fit the female connection in the
side of the logic cover. The air motor is lubricated through
a servo meter located below the lubricator reservoir.
The servo meter injects a quantity of oil directly into
the solenoid valves and air motor during each cleaning
cycle. The lubrication should be done using a light grade
hydraulic oil with a viscosity rating of 150 VC 15-20 (SAE
5W). When filling the reservoir for the first time or refilling
an empty reservoir, you must manually prime the pump to
distribute the oil through the system. The servo meter has
an adjustment that goes from 0 (-) to 45 (+) clicks and a
push button to prime the lubricant oil. Refer to Figure 2.
Pull the servo meter knob to the unlock position (A).
Set the servo meter knob at 45 (+) and press the button
appromimately 50 to 60 times.
Turn the servo meter knob counter-clockwise to 0 (-)
and set at 3 (+) clicks.
Push the servo meter knob back into the locked position (C).
The amount of lubricant can be adjusted by turning the
adjustment knob located on the servo meter.

Robotic Nozzles vs. Clamp Block
Program the robot to position the Mig nozzle directly above
and centered to the reamer blade above the QRC
TM
-2000.
Insert the nozzle to the required depth to allow complete
cleaning of the tip and nozzle without damaging the torch
consumable parts. (Please refer to section 3.11).
At this time the cycle start signal (pulse .5 to 1.0 seconds)
should be sent to the QRC
TM
-2000 from the robotic
controller. Then the QRC
TM
-2000 will clamp the nozzle and
perform the cleaning operation.
Once the reamer completes the cleaning cycle, the cleaning
station will send a cycle complete signal back to the robot
controller. At this time, the torch is removed from the
QRC
TM
-2000 and the work cycle continues.
3.10 Air Flow Control Valve
The air flow control valve provides an adjustment for the
reamer blade feed rate. The amount of spatter buildup
will determine the required reamer blade feed rate. The
heavier the spatter, the slower the reamer blade feed
rate that should be used. If a smaller amount of spatter
accumulates, the feed rate can be set faster.
Adjusting the air flow control valve:
There is an air flow control valve inside the unit as
shown in Figure 8.
The feed rate may require adjusting for different
applications.

(.620”/15,7mm O.D. x .422” / 10,7mm I.D.) and clamp
block “B” (QRC2102-B / 1”(25,4mm)).
Please make sure that the reamer blade and clamp block
fit the need of your application.
Setting up the Torch with Gauges
There are three sizes of gauges (1/2” (12,7mm), 5/8”
(15,9mm) and 3/4” (19,1mm)). These gauges are
available as a set under Part No. QRC
TM
-PG2.
Determine O.D. of reamer blade being used.
Slip proper gauge on O.D. of reamer blade.
Screw in tip index shaft.
Determine O.D. of contact tip being used.
Slip proper alignment sleeve on pointer.
Bring torch down to where the I.D. of contact tip
touches pointer, push alignment sleeve up and over
contact tip to gauge if torch is set at 90 degrees.
Once this is established, back the torch off from the
pointer to allow room to remove the pointer and
alignment sleeve.
Bring the torch back down to where the nozzle
touches top of the gauge.
This allows the programmer to set up for the stroke
of the reamer blade in the cleaning sequence.
NOTE
Using a flush or protruded nozzle, adjust the
reamer blade stroke, leaving a gap between
the nozzle and the top of the gauge. For
flush nozzles: leave a 1/8” (3,2mm) gap.
For protruded nozzles: leave a 1/4” (6,4mm)
gap.
