Frequently Asked Questions - Circulator LINCOLN ELECTRIC

How do I set the automatic weekly timer for the Circulator?

Press ▼ on the PLC to show date/time, then press ESC. Navigate to LOGO! Settings > Program > Set Parameter > Timer 1. Set the days (D1, D2, D3) and on/off times. Default is Monday-Friday 07:00-17:00. Exit with ESC.

What does the system failure light indicate and how do I troubleshoot?

The SYSTEM FAILURE light (B) and buzzer indicate a fault. Check the PLC display and VFD for error codes. Common causes: high filter pressure, compressed air issues, or motor problems. Refer to the troubleshooting section in the manual.

How often should the filters be replaced?

Replace filters when damaged, if extraction capacity is significantly reduced, or if pressure alarms persist despite cleaning. Lifetime depends on weld fume composition and humidity. Always replace both filters together.

What is the purpose of the offline cleaning cycle?

Offline cleaning occurs when the system is off for at least 1.5 hours and filter differential pressure exceeds the set point (default 1200 Pa). It uses compressed air pulses to clean cartridges, with dust collected in the drum below.

Can I use the Circulator in manual mode?

Yes, press MANUAL START (F) to run the fan outside scheduled hours. The system will run for a preset overtime duration (default 2 hours). Use for incidental needs.

What compressed air quality is required?

Compressed air must be dry and oil-free per ISO 8573-3 class 6, at a pressure of 5-6 bar (75-90 psi). Connect via the quick coupling (ISO 6150 B). Maximum consumption is 5.3 ft³/min at 87 psi.

How do I adjust the airflow direction from the nozzles?

Rotate the adjustable nozzles to direct air toward the welding fume layer, avoiding obstructions. The throw distance is controlled by fan speed (0-60 Hz via VFD) and nozzle dampers. Use the lowest speed for effective circulation.

What safety precautions must be observed during installation?

Only qualified personnel should install. Turn off input power and lockout/tagout. Ground the unit per National Electrical Code. Ensure adequate clearance (3 ft). Do not stack. Use proper lifting equipment; the unit weighs 1764 lb.

How do I reset the filter hour counter after replacing filters?

Press F1 and F4 simultaneously on the PLC display to reset hour counters (except total hours). This ensures the cleaning system does not attempt to clean new filters during the first 40 hours of operation.

What should I do if the buzzer alarms continuously?

Check the PLC display for pressure or fault codes. If filter pressure remains above 1800 Pa after 2 hours of cleaning, the alarm will sound. Inspect for clogged filters, low compressed air, or full collection drum. Empty drum and replace filters if needed.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

FOR ENGINE POWERED EQUIPMENT.

1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.

1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.

1.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact

with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated.

1.d. Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.

1.e. In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.

1.f. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.

1.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.

1.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.

ELECTRIC AND MAGNETIC FIELDS MAY BE DANGEROUS

2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines

2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.

2.c. Exposure to EMF fields in welding may have other health effects which are now not known.

2.d. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:

2.d.1. Route the electrode and work cables together - Secure them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work cables. If the electrode cable is on your right side, the work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as possible to the area being welded.
2.d.5. Do not work next to welding power source.

ELECTRIC SHOCK CAN KILL.

3.a. The electrode and work (or ground) circuits are electrically "hot" when the welder is on. Do

not touch these "hot" parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.

In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.
  • DC Manual (Stick) Welder.
  • AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically "hot".
3.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical (earth) ground.
3.f. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically "hot" parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.
3.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
3.j. Also see It ems 6.c. and 8.

ARC RAYS CAN BURN.

4.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding hardfacing (see instructions on container or SDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and within applicable OSHA PEL and ACGIH TLV limits using local exhaust or mechanical ventilation unless exposure assessments indicate otherwise. In confined spaces or in some circumstances, outdoors, a respirator may also be required. Additional precautions are also required when welding on galvanized steel.

1. b. The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.
   5.c. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products.
   5.d. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.
   5.e. Read and understand the manufacturer's instructions for this equipment and the consumables to be used, including the Safety Data Sheet (SDS) and follow your employer's safety practices. SDS forms are available from your welding distributor or from the manufacturer.
   5.f. Also see item 1.b.

WELDING AND CUTTING SPARKS CAN CAUSE FIRE OR EXPLOSION.

6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to "Safety in Welding and Cutting" (ANSI Standard Z49.1) and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been "cleaned". For information, purchase "Recommended Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held Hazardous Substances", AWS F4.1 from the American Welding Society (see address above).
6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B "Standard for Fire Prevention During Welding, Cutting and Other Hot Work", available from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
6.j. Do not use a welding power source for pipe thawing.

CYLINDER MAY EXPLODE IF DAMAGED.

7.a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to physical damage.
• A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other electrically "hot" parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-I, "Precautions for Safe Handling of Compressed Gases in Cylinders," available from the Compressed Gas Association, 14501 George Carter Way Chantilly, VA 20151.

FOR ELECTRICALLY POWERED EQUIPMENT.

8.a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical Code, all local codes and the manufacturer's recommendations.

GENERAL DESCRIPTION

The CIRCULATOR is a free-standing general filtration system that prevents accumulation of welding fume by continuous filtration of polluted air. It consists of a central filter unit, a fan in a sound absorbing case, an outlet unit with adjustable outlet nozzles, a silencer and a control panel with variable frequency drive and PLC.

The air containing welding fumes is extracted through the air inlet module on top of the filter unit. The larger particles and any sparks are separated by a labyrinth-shaped spark arrester. Subsequently, the air is cleaned by the main filter cartridges. The air is then passed through the extraction fan and a duct silencer. The clean air is blown back into the workshop by the outlet unit with adjustable nozzles. The unit contains an automatic pulse cleaning system that cleans the filter cartridges using compressed air. The dust and dirt particles are collected in the drum that is located underneath the filter unit.

The CIRCULATOR compliments the natural and forced ventilation system(s) to reduce welding fume in the general workshop area.

UNCRATING

1. Position the filter leg base in the desired location and raise it in to position.

OUTLET NOZZLES

To optimize system performance of the CIRCULATOR, position the nozzles and regulate the air flow as follows:

• Direct the nozzles at the welding fume layer without obstruction.
• Direct the nozzles to the section of the facility where the highest concentration of welding fume occurs.
• Set the correct throw by regulating the airflow. (Throw is the distance that pressurized air travels.)

The airflow volume can be regulated by adjusting as follows.

1. Fan speed is automatically regulated by a delta P sensor. Set point can be change to control Speed.

2. Outlet nozzle damper (nozzles are adjustable)

See Figure B.2 and B.3 for more guidelines to achieve a proper air circulation.

The throw can be adjusted by the potentiometer FAN SPEED 0-100%. The fan speed ranges between 0Hz and 60Hz. The maximum throw is 130 ft. (40m) at an air velocity of 1 to 1.6 ft/s (0.3 to 0.5m/s).

It is recommended to not over-dimension the capacity, but to strive for a proper air circulation at the lowest possible fan speed.

• Adjust the nozzles to the best position. See Figure B.2.
• Regulate the correct throw by adjusting the Pressure (Pa) value in VFD parameter.

For FC102 VFD use parameter 2021 Set point1.

For FC101 VFD use parameter 310 Preset Reference.

See Figure B.3

Throw Airflow/Nozzle Total Airflow Fan Speed Frequency

MAINTENANCE

AUTOMATIC FILTER CLEANING

Each time the system is switched off after having been run for at least 1hr 30 min, an automatic cleaning cycle will take place. During this cycle, both filter cartridges are cleaned by compressed air jets from the SELF CLEANING UNIT SYSTEM. The dust and dirt particles end up in the drum underneath. The filter cleaning procedure takes approx. 1hr 30 min.

The automatic filter online cleaning system will also be activated as soon as the pressure rises above 2000 Pa (8 in. WG) during use. Off-line cleaning will start once the pressure rises above 1200 Pa (4.8in WG) for 1 hr 30 min.

Buzzer beeps, if the pressure does not drop below 1800 Pa (7.2in WG) after 2 Hours of cleaning,

To ensure initial operating efficiency of the filter cartridges, they should not be cleaned during the first 40 hours after filter replacement. This is achieved by resetting the hour counter.

PERIODIC MAINTENANCE

The product has been designed to function without problems for many hours with minimal maintenance. In order to guarantee this, some simple, regular maintenance and cleaning activities are required which are described below. If you observe the necessary caution and carry out the maintenance at regular intervals, any problems that occur will be detected and corrected before they lead to a total breakdown.

The indicated maintenance intervals can vary depending on the specific working and ambient conditions. Therefore it is recommended to thoroughly inspect the complete product once every year other than the indicated periodic maintenance.
