1.03 DESCRIPTION

During welding, spatter accumulates on the shielding nozzle and consumables (contact tip,

diffuser). If this spatter is not removed, it will accumulate until the shielding gas is disrupted

causing inadequate gas coverage and porosity in the weld seam. The cleaning station helps

remove and prevent the build up of spatter.

How it works:

The robot moves the gun into the tank ﬁlled with anti-spatter ﬂuid and activates the ultrasonic

generator which makes the Piezo transducers vibrate the tank at a high frequency. The vibrating

waves spread throughout the liquid in the tank. When they reach the surface of the weld

consumables, they form compression and decompression waves that create micro-bubbles

(cavitation), which implode. This phenomenon triggers a mechanical action that breaks the

Introduction

safety and Operating instructiOns

QRC-3000

bond of the weld spatter at the molecular level. This breaks the bond of the spatter from the

nozzle as well as the gas diffuser and tip. It also cools down all the components. The robot

then removes the gun from the tank and a blast of air is pulsed through the gun and out the

gas diffuser. This further removes any loose spatter and excessive ﬂuid. The nozzle, tip and

diffuser are cleaned, cooled and ready to continue welding.

This process has many advantages over conventional nozzle reamers:

Cools, cleans and extends consumable life

Non-contact and no moving parts

Cleans all types and sizes of nozzles

Automatic ﬂuid dispensing

Limit switch activated or robotic I/O controlled

Eliminates programming nozzle to reamer blade

Shop air is not required for operation

Uses standard 120VAC power

The ﬂuid level in the tank is automatically maintained with a peristaltic pump and ﬂoat switch.

The pump pumps the ﬂuid from standard anti-spatter containers. The container can be placed

on the shelf on the optional stand.

This unit has a two year warranty.

SECTION 2:

SAFETY PRECAUTIONS

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, and be 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.)

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 qualiﬁed and/or trained personnel only.

Do not contact electrically live parts. Always wear dry welding gloves that are in

good condition. Aluminized, protective clothing can become part of the electrical path. Keep oxygen

cylinders, chains, wires, ropes, cranes, and hoists away from any part of the electrical path. All

ground connections must be checked periodically to determine if they are mechanically strong,

and electrically adequate for the required current. When engaged in AC welding/cutting under

wet conditions or where perspiration is a factor, the use of automatic controls for reducing the

no load voltage is recommended to reduce shock hazards. Accidental contact must be prevented

when using open circuit voltage exceeding 80 volts AC, or 100 volts DC by adequate insulation

or other means. When welding is to be suspended for any length of time, such as during lunch or

overnight, all electrode holders and electrodes should be removed from the electrode holder and

the power supply should be turned off to prevent accidental contact. Keep MIG-Guns, electrode

holders, Tig torches, Plasma torches, and electrodes away from moisture and water. See safety

and operating references 1, 2, and 8.

SMOKE, FUMES, AND GASES CAN BE DANGEROUS TO YOUR HEALTH

Ventilation must be adequate to remove smoke, fumes, and gases during operation

to protect operators and others in the area. 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 operating area. Use air-supplied respirators if ventilation is not adequate

to remove all fumes and gases. Oxygen supports, and vigorously accelerates ﬁre and should never

be used for ventilation. See safety and operating references 1, 2, 3, and 4.

Safety Precautions

2-4

safety and Operating instructiOns

QRC-3000

ARC RAYS, HOT SLAG, AND SPARKS CAN INJURE EYES AND BURN SKIN

Welding and cutting processes produce extreme localized heat and strong

ultraviolet rays. Never attempt to weld/cut without a federally compliant welding

helmet with the proper lens. 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. Approved shielding curtains

and appropriate goggles should be used to provide protection to others in the surrounding area.

Skin should be protected from arc rays, heat, and molten metal. Always wear protective gloves

and clothing. 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. Hightop work shoes provide adequate protection from foot burns. For added protection,

use leather spats. Flammable hair preparations should not be used when welding/cutting. Wear

ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in

an individual booth painted with a low reﬂective material such as zinc oxide. See safety and

operating references 1, 2, and 3.

WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS

Combustibles reached by the arc, ﬂame, ﬂying sparks, hot slag, and heated

materials can cause ﬁre and explosions. Remove combustibles from the work

area and/or provide a ﬁre watch. Avoid oily or greasy clothing as a spark may

ignite them. Have a ﬁre extinguisher nearby, and know how to use it. If welding/

cutting is to be done on a metal wall, partition, ceiling, or roof, precautions must

be taken to prevent ignition of nearby combustibles on the other side. Do not

weld/cut containers that have held combustibles. All hollow spaces, cavities, and containers

should be vented prior to welding/cutting to permit the escape of air or gases. Purging with inert

gas is recommended. 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. See safety and operating references 1, 2, 5, 7, and 8.

NOISE CAN DAMAGE HEARING

Noise from the air carbon-arc process can damage your hearing. Wear protective

hearing devices to ensure protection when noise levels exceed OHSA standards.

Adequate hearing protection devices must be worn by operators and surrounding

personnel to ensure personal protection against noise. See safety and operating

references 1, 2, and 6.
