W ARNINGS AND L ABELS
HIGH VOLTAGE: The voltage of the Weld Station is dangerous once connected to a power supply. Incorrect installation may cause damage to the equipment, serious injury, or death. Consequently, it is essential to comply with instructions in this manual, local and national safety rules, and follow all safety procedures including proper lock out and tag out procedures. Hazardous Voltage: The Variable Frequency Drive (VFD) uses large capacitors which can hold a charge long after the power disconnect has been used to disconnect power from the unit. Do not service the panel until the VFD has fully discharged. GROUND CONNECTION: Proper grounding of the equipment and electrical panel is essential. Do not attempt to operate the equipment without electrically grounding the panel. The connection to the earth ground must be proper and provide a low impedance path to the earth to prevent hazardous voltages from appearing on equipment

M OVING THE W ELD S TATION A IRE U NIT
There are various ways to move the Weld Station Aire main unit. If the Weld Station unit has NOT been
uncrated or is still on the pallet, then it can easily be moved by using a fork lift truck. Place the forks under the pallet's main beams and simply lift the unit. Keep in mind, the motor end (top) of the unit is heavier and forks may need to be shifted toward the motor end. If the Weld Station unit has been uncrated, then it can easily be moved by using a fork lift truck. Attach the lifting chains or cables to the fork head ache bar. Attach the other end of the lifting chains or cables to the lifting lugs. The top of the unit can then be lifted using the fork lift truck. Place a wooden '2 x 4 underneath the raised end of the unit. This wood piece will create a gap allowing the forks to be slid under the unit. Make sure not to scratch or damage the unit.

M AINTENANCE C LEANING THE I NTAKE S PARK B AFFLES
The Reverse Flow TM spark baffles and metal mesh spark baffles are designed for inhibit and reduce the energy of sparks. Because these bafflers and filters are the first in line concerning air flow, they become soiled by welding smoke and need to be cleaned periodically. How often they need to be cleaned is dependent upon the amount and type of welding performed. Feedback from welding instructors, which we greatly value, indicates that many welding labs clean them every six to twelvemonths. It is recommends that educational facilities inspect the baffles every quarter, or every 3 months, and clean them as needed. It is recommended that the baffles can be washed with a garden hose or, if carefully used, a pressure washer. Be sure they are dry before placing them back into the Weld Station. Many welding instructors assert the easiest and most convenient way to clean the baffles is by first simply shaking the loose debris from the baffles, and then spraying them with a compressed air hose. Whatever method you prefer, it is IMPORTANT that the baffles be cleaned periodically. If the baffles are not cleaned, they can affect the performance of the Weld Station, restricting of air flow and reducing the performance quality. Examine the metal mesh filters at the inlet of the unit. These filters should be washed when they become visibly dirty / contaminated. How often they need to be cleaned is dependent upon the amount of welding performed and the given application. If they are not cleaned, they can affect the performance of the unit by reducing air flow.

It is important to keep the filters clean and replaced on the proper interval for the proper operation of the Weld Station Aire. The interval when the filters must be changed depends upon the specific application. Welding and grinding frequency, the type of particulate that is being removed, the type of filters being used, and the type of welding being performed all effect the filter replacement interval. When prefilter is being used, and using default filters, the filter needs to be replaced when reaching a pressure drop of 2 in. H 2 O. The process for determining your specific filter change interval is based on many variables. Please feel free to establish a filter change interval that meets you application and desired performance results. By properly monitoring the filters you will improve the efficiency of the units. Proper filter replacement is important to optimal performance of the Weld Station Aire Where to Start Start by making copies of the attached log sheet. This log sheet should be filled out for each Weld Station you have in your system. Make a physical check to ensure that the smoke / particulate is being removed through the intakes spark baffles. This can be done by a simple visual check during normal operation. There should be a reduced level of visible smoke when the unit is in operation. During maintenance, examine the intake spark baffle at the back of the welding booth(s). These filters should be washed when they become visibly dirty / contaminated. The differential pressure sensor does measure across intake spark baffles; however, visual inspection is required.

If this has not been set, the overload will require being reset via the red button marked 'Reset'. Wire numbers have been added to the wiring diagram to aid in both the diagnostic issues as well as the maintenance and service issues while in the field. The wire numbers will be shown in small Black numbers at each end of the wire. The wires are be numbered by the 'node', meaning that several wires connecting into one point will have the same number. Labels are placed on the terminal blocks as well as the wires. Starting in December of 2009, Clean Air Industries switched over to LED lighting to reduce operating costs and provide a greener system. A Weld Station Aire may be equipped with one or two lights for each booth. A second light may be added after the Weld Station has been installed for additional lighting. Your Clean Air Industries sales representative can help in arranging this addition. Multiple electrical options / accessories are available for the Weld Station. If an electrical option has been added, then see the 'Weld Station Users Manual' for additional information.
