MUL TI-SOURCEOPERATOR’S MANUALFor use with machines Code 10668October, 2000IM692Safety Depends on YouLinco ln arc welding equipment is designed and built with safety in mind. However, your overall safety can be increased by proper instal-latio n ... and tho ughtful o peratio n on your part.DO NOT INSTALL,OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READ-ING THIS MANUAL AND THE SAFETY PRECAUTIONS CON-TAINED THROUGHOUT.And,most importantly, think before you act and be careful.Copyright © 2000 Lincoln Global Inc.This manual covers equipment which is nolonger in production by The Lincoln Electric Co. Speci cations and availability of optional features may have changed.Mar ‘95Mar ‘95Mar. ‘93for selecting a QUALITY product by Lincoln Electric. We want you to take pride in operating this Lincoln Electric Company product ••• as much pride as we have in bringing this product to you!Read this Operators Manual completely before attempting to use this equipment. Save this manual and keep it handy for quick reference. Pay particular attention to the safety instructions we have provided for your protection.The level of seriousness to be applied to each is explained below:vvOther indicator lights include the amber Thermal light that signals when the long term output current limit has been exceeded. This limit is determined by a ther-mostat sensing the temperature of the negative output lead from the secondary coils. The white Power light indicates when the Control board is energized. The three lights are high intensity LEDs for improved visi-bility in daylight.The Output Power display uses high intensity LEDs to indicate the percentage of full rated output the machine is supplying.Two additional thermostats protect the machine in the case of fan failure or blocked air flow. The SCR heat sink thermostat responds first to loss of air flow at nor-mal output loads. This thermostat will disable the machine output. The transformer iron rear thermostat senses that the lamination (and thus the coil insula-tion) is over heating (which can happen even if the output is disabled). This thermostat will interrupt power to the Control board causing the input contactor to open until the iron cools.The only user controls are an on-off toggle Power switch that energizes the machine and a 10 A circuit breaker protecting the fan auxiliary against short cir-cuits.DESIGN FEATURES - ALL MODELSSPECIFICATIONS,DESIG N FEATURES AND ADVANTAGESCase parts are predominantly stainless steel, the PC boards are potted in trays, the controls are sealed, all machine coils are copper and the whole transformer is varnish dipped to maximize environmental withstand capability. The coils are all conservatively rated for long life.The Multi-Source output regulates against wide changes in output loading and input line voltage varia-tions to supply a consistently stable voltage high enough to allow the Multi-Welds to provide good man-ual electrode capability.SAFETY PRECAUTIONSGENERAL DESCRIPTIONThe Multi-Source is designed to supply power to the Multi-Weld welders. It has a wide range three phase AC input and can be operated on 50 or 60 Hz. The Multi-Source output peak voltage regulates against wide changes in output loading and input line voltage variations to supply a consistently stable voltage high enough to allow the Multi-Welds to provide good man-ual electrode capability.Primary input voltage taps are selected by a single movable link on the reconnect panel. Main trans-former auxiliary windings power the firing circuit and fan motor. The control auxiliary transformer has a sin-gle, wide range primary and is not reconnectable.The Fan As Needed feature is activated by an output current of 20 Adc or a thermostat on the main trans-former iron.An independent safety circuit on the Control board monitors the voltage peaks and opens the input con-tactor if the limit is exceeded. The green Safe Output light indicates when the machine output voltage isFACTORY INSTALLED OPTIONS / ACCESSORIESThere are no factory installed options.FIELD INSTALLED OPTIONS / ACCESSORIESK1735-1 Multi-Weld 350, Multi-process controller.K857, K857-1 Remote Control, Control Multi-Weldremotely (25 or 100 ft.).K1736-1 Distribution Box, Connects up to 10 Multi-Welds.K449 LN-25, Across the arc wire feeder.K1788-1 Roll Cage, Protect power source, facilitate moving, store cable.K1806-1 Multi-Weld Four Pack, Mounting / lift rack for M-S and four M-Ws.K1807-1 Multi-Weld Eight Pack, Mounting / lift rack for M-S and eight M-Ws.S20428Paralleling Kit,Allows two machines toequally share double load.MACHINE CALIBRATION SPECIFICATIONThe Multi-Source digital display is controlled by a cur-rent sensing circuit on the Control board. The display reads 100 when machine output is a little over 40 kW. To recalibrate the display, the machine output may loaded with Multi-Weld welders or resistive grids or a combination of both to obtain an output of 533 Adc as read by a calibrated standard ammeter. Trimmer resistor R49 may be adjusted to cause the display to read 100.This Troubleshooting Guide is provided to help you locate and repair possible machine malfunctions.Simply follow the three-step procedure listed below.Step 1.LOCATE PROBLEM (SYMPTOM).Look under the column labeled “PROBLEM (SYMP-TOMS)”.

For your safety and to avoid Electrical Shock, please observe all safety notes and precautions detailed throughout this manual.__________________________________________________________________________5. LEDs 1 through 6 indicate gate signals are being sent to the main SCRs 1 through 6 respectively. If LED2 on the Control board is bright, along with LEDs 7, 8, and 9 on Firing board, and LEDs 1through 6 are unequal in brightness, check to make sure lead 231 between Control board and Firing board is not broken. (If lead 231 is removed while the machine output is at open circuit, the output voltage peaks may be unregulated and cause the over-voltage protection circuit to open the input contactor. The over-voltage protection circuit may disabled by disconnecting lead 222D at the nega-tive output stud or at pin 1 of P2. NOTE: Themachine may not be used for welding with the pro-tection circuit disabled.6. If one or more of LEDs 1 through 6 are off, LEDs 7,8, and 9 are on and the voltage on lead 231 from the Control board (pin 13, P5 to pin 12, P5) is 3 to 13Vdc replace the Firing PCB.PC BOARD TROUBLESHOOTING GUIDE - FIRING P .C.BOARD1. LEDs 1 through 9 must be lit when the Multi-Source is turned on and the Control board is sending an enable signal to the Firing board (pin 7 in P8 is low in reference to common at pin 12 in P5).2. LEDs 7, 8, and 9 indicate AC power being supplied to the P.C. board from auxiliary windings on the main transformer (T1). If a LED is not on, turn the machine off and unplug P8 from the firing board.Turn the machine back on and check the following voltages:3. If all voltages are present, turn power off, and plug P5 back into J5. Turn power back on. If LEDs 7, 8or 9 are still not lit, replace Firing PCB.4. If voltages were not present, check the circuit back through the external dropping resistors to the auxil-iary windings for a possible open resistor or wire.PC BOARD TROUBLESHOOTING GUIDE - CONTROL P .C.BOARD1. The white Power light on the machine control panel indicates that the Control board power supply is being supplied by rectified secondary voltage from the Control transformer (T2) by way of the Power switch and transformer iron rear thermostat.2. LED1 indicates machine output voltage. At normal output voltages, LED1 will be brightly lit.3. LED2 indicates the level of the control signal to the Firing board. The brightness of LED2 is inversely proportional to machine output because the control signal increases as the machine output decreases.4. LED3 lights when the current amplifier senses an output current over about 10 amps and sends a sig-nal to turn the cooling fan on. If LED3 is on but the fan is not , there could be a problem with the fan motor or the fan motor drive circuit (see LED6).5. LED4 says that some signal, either thermostat, out-put current or output over-current is calling for the fan to operate.6. LED5 tells us that the current signal from the shunt is too high. If LED5 is lit for 5-8 seconds, the enable signal to the Firing board is made high to shut off the output SCRs. In the case of a short duration current overload, LED5 may only be briefly litbecause, in normal operation, the machine output immediately goes to zero. Once disabled, the out-put will remain off for about 75 seconds.7. LED6 indicates that the input to the fan motor opto triac driver has been energized. LED6 should be on as long as the fan motor runs. LED6 and the fan motor will be on for about 5 minutes after LED4goes off.8. LED7 will light when the shorted SCR circuit acti-vates. A positive voltage on the negative output stud (AC instead of DC on the output studs) will activate a circuit causing the input contactor to open. This circuit is active only when the enable signal to the Firing board is high (the output is off).The contactor will remain open (and the whitePower light will remain on) until the Power switch is turned off (or the input power to the machine is oth-erwise removed) for about 1 second and then turned on again.9. The green Safe Output light on the control panel when the machine output voltage is present and safe. It lights when the machine output is between 40 Vdc and 113 volts peak. 10. The yellow Thermal light on the front panel lightswhen the open thermostat signal is sent to the fan control and output disable circuits.Now Available...12th EditionThe Procedure Handbook of Arc WeldingWith over 500,000 copies of previous editions published since 1933, the Procedure Handbook is considered by many to be the “Bible” of the arc welding industry.This printing will go fast so don’t delay.

ENVIRONMENTAL CONDITIONSTemperature：Min 14°F (-10°C) / Max +140°F (+60°C)Relative Humidity: Max 90%WARNING:The temperature limits should be applied to the pump components and must be respected to avoid possible damage or malfunction.Nevertheless, it should be understood that for a given oil, the real functioning temperature range also depends on the variability of the viscosity of the oil itself with different temperatures. Specifically:●Under the temperature below 14°F, the viscosity of some oils can greatly exceed the maximum allowed bythis pump, which will cause that the static torque required to start the pump would be excessive, and the pump may overload and damage.●Under the temperature above +140°F, on the other hand, the viscosity of some oils can drop well belowthe minimum allowed by this pump, which will cause that the back pressure increases, and the pump may degrade in performance with obvious reductions in flow rate.2. ELECTRICAL POWER SUPPLYThe AC pump must be supplied by a single-phase alternating current line whose nominal values are shown in the table TECHNICAL SPECIFICATIONS above. The maximum acceptable variations from the electrical parameters are:Voltage: ± 5% of the nominal valueFrequency: ± 2% of the nominal valueWARNING:Power from lines with values outside the indicated limits can damage the electrical components.3. WORKING CYCLEUnder normal operating conditions they can function continuously with no limitations.WARNING:DO NOT KEEP THE PUMP WORK IN BYPASS CONDITION MORE THAN 2 MINUTES.Whenever a particular installation carries the risk of functioning in bypass mode for longer periods of time, it is necessary to return the bypassed flow to the suction tank, but not recirculated inside the pump.4. FLUID ALLOWED / FLUIDS NOT ALLOWEDALLOWED: Oil with a Viscosity from 500 to 2000 Cst (at working temperature)NOT ALLOWED RELATED DANGERGasoline Fire - explosionInflammable liquids with PM < 55℃Fire - explosionWater Oxidation of the pumpLiquid food products ContaminationCorrosive Chemicals Corrosion of the pumpInjury to peopleSolvents Fire – explosionDamage to gasket sealsWARNING:The gear pump is sensitive to polluted fluids; avoid dispensing fluids with impurities.NOTE: Apply Teflon® to all connecting fittings.Unpack the package, and take out the mobile body, handle and accessories.1. Take out the up handle, insert it on the trolley (See Fig. 1)Fig. 12. Screw & fix the handle tightly. (See Fig. 2)3. Install the pump on the plate, tightly screwed, Screw the suction hose & delivery hose on the pump, Connect the nozzle with the pump. (See Fig. 3)HYDRAULIC CONNECTION● Before connection, make sure that the hoses and the suction tank are free of dirt and thread residue thatcould damage the pump and its accessories. ● Always install a metal mesh filter in the suction hose.● Before connecting the delivery hose, partially fill the pump body with oil to avoid the pump running dryduring the priming phase.Suction HoseMinimum nominal recommended diameter: 1in.Use a hose suitable for functioning under suction pressure. Delivery HoseMinimum nominal recommended diameter: 1in.WARNING:1. Hoses and/or line components unsuitable for use with oil or with inadequate nominal pressures can cause damage to objects or people, as well as pollution.2. Use oil resistant pipe sealant or Teflon® Tape on all pipe threads.3. Check all the connections before each use. Tighten them if necessary. Loosening of the connections (threaded connections, flanging, gasket seals) can cause serious ecological and safety problems.SUCTION AND DELIVERY LINESDELIVERYThe proper pump should be chosen considering the viscosity of the oil to be pumped and the characteristics of the system attached to the delivery of the pump. The improper application of the oil viscosity and the characteristics of the system could create unexpected large back pressure which may cause the (partial) opening of the pump bypass and consequently reduce the flow rate.It is recommended to use shorter tubing and/or tubing with a larger diameter to reduce system resistance, so that the pump would function equally to the viscosity of the oil being pumped.Fig. 2Fig. 3SUCTIONThe gear-type oil pumps are characterized by excellent suction capacity. In fact, the characteristic flow rate/ back pressure curve remains unchanged even at high pump suction pressure values.The pump will prime to a height of 6.5 feet (2 meters) when the suction hose is empty and the pump is filled with fluid. On tanks with a suction height over 6.5 feet, a foot valve may be required on the bottom of the suction tube to hold the fluid in the tube. Do not install the pump with a height higher than 9.8 feet (3 meters), or the pump will lose its prime.WARNING: In cases where the suction tank is installed higher than the pump installation, it is recommended to install an anti-siphon valve to prevent accidental diesel fuel leaks. Care should be taken during the installation process in order to control back pressure.NOTE: Before use, make sure all the connections are sealed well.1. Place the drum on the trolley.2. Put the suction hose into the drum. Move the mobile unit to where you need to dispense.3. Put the nozzle to where you need to dispense, then connect the power cord. Turn on the switch, andstart dispensing.4. After dispensing, close the pump, and take back the nozzle.WARNING: Running in bypass mode with the delivery closed is only allowed for brief periods (2 minutes maximum).USAGE OF THE OIL DIGITAL CONTROL VALVE1.
