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)”. This column describes possible symptoms that the machine may exhibit. Find the listing that best describes the symptom that the machine is exhibiting.Step 2.POSSIBLE CAUSE.The second column labeled “POSSIBLE CAUSE” liststhe obvious external possibilities that may contribute to the machine symptom.Step 3.RECOMMENDED COURSE OF ACTIONThis column provides a course of action for the Possible Cause, generally it states to contact your local Lincoln Authorized Field Service Facility.If you do not understand or are unable to perform the Recommended Course of Action safely, contact your local Lincoln Authorized Field Service Facility.HOW TO USE TROUBLESHOOTING GUIDEService and Repair should only be performed by Lincoln Electric Factory Trained Personnel.Unauthorized repairs performed on this equipment may result in danger to the technician and machine operator and will invalidate your factory warranty. 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.

林肯DC1000/NA5自动埋弧焊机维修经验
本内容介绍了林肯埋弧焊机的维修经验，这种机器在国内埋弧自动生产线用的非常多，焊接性能和焊接质量都很好，最重要的是质量可靠，经久耐用。
但并不代表永远不会坏。
由于是进口机，坏了维修会比较麻烦，一般控制板坏了林肯公司以及经销商都不会进行维修，只是更换新板。
而且控制板的价格都不菲，少则几千，贵的几万。
为了减少客户的维修成本，小弟对林肯一系列的进口和国产焊机整机电路以及控制板工作原理进行了一些研究，学习到一点皮毛，这回正好运用这点皮毛技术为客户解决一点难题，为客户节约了维修成本，最大限度缩短了设备停工时间，将机器故障带来的损失减少到了最少。
好了废话不多说，来看看林肯机器到底是怎幺修的，有图有真相哦。

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!1. Output rating in watts is equivalent to volt - amperes at unity factor.Output voltage is within +/-10% at all loads up to rated capacity.When welding available auxiliary power will be reduced.Internal combustion engines are designed to run in a level condition which is where the optimum perfor-mance is achieved. The maximum angle of operation for the engine is 15 degrees from horizontal in any direction. If the engine is to be operated at an angle,provisions must be made for checking and maintain-ing the oil at the normal (F ULL) oil capacity in the crankcase in a level condition.When operating at an angle, the effective fuel capaci-ty will be slightly less than the specified 9 gallons (34Liters).LIFTINGThe RANGER 3 PHASE weighs approximately 575lbs.(261kg) with a full tank of gasoline. A lift bail is mounted to the machine and should always be used when lifting the machine.HIGH ALTITUDE OPERATIONIf the RANGER 3 PHASE will be consistently operat-ed at altitudes above 5000 ft(1524m), a carburetor jet designed for high altitudes should be installed. This will result in better fuel economy, cleaner exhaust,and longer spark plug life. It will not give increased power which is decreased at higher altitudes. Engine horsepower is reduced by 3.5% per 1000feet(304.8m) for altitudes above 377 feet(115m).Do not operate a RANGER 3 PH ASE with a highaltitude jet installed at altitudes below 5000ft.(1524m) This will result in the engine runningtoo lean and result in higher engine operatingtemperatures which can shorten engine life.-----------------------------------------------------------------------Contact your local Kohler Authorized Dealer for highaltitude jet kits that are available from the engine •Shut off welder and allow muffler to cool beforetouching muffler.------------------------------------------------------------------------The RANGER 3 PHASE is shipped with the exhaust coming out on the left side. The exhaust can be changed to the opposite side by removing the two screws that hold the exhaust port cover in place and installing the cover on the opposite side. (Operating the RANGER 3 PHASE without the cover in place will result in a higher noise level and no increase in machine output.)LOCATION / VENTILATIONThe welder should be located to provide an unrestrict-ed flow of clean, cool air to the cooling air inlets and to avoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welder so that engine exhaust fumes are properly vented to an outside area.STACKINGRANGER 3 PHASE machines cannot be stacked.CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERSShut off welder before making any electrical connections.------------------------------------------------------------------------WIRE FEED (CONSTANT VOLTAGE)CONNECTION OF LN-15 ACROSS-THE-ARC WIRE FEEDERThe LN-15 has an internal contactor and the electrode is not energized until the gun trigger is closed.

DC_1500林肯焊机的故障诊断
DC—1500林肯焊机的故障诊断樊东海(宝鸡石油钢管厂 721008) 摘 要 简要叙述了林肯焊机的结构特点及控制调节电路的基本原理,介绍了三种典型故障的产生原因和诊断路径,供维修时参考。
主题词 焊机 原理 故障 分析 1 电路结构特点及基本原理DC—1500林肯焊机按其功能可分为主电路、操作电路、控制调节系统和保护电路四大部分。
1.1 主电路及操作电路主电路采用带平衡电抗器的双反星形可控硅整流电路,比起三相半波整流和三相桥式整流具有以下特点:(1)输出电压稳定,脉动小;(2)消除了整流变压器的直流磁化,变压器二次绕组的利用率高,体积小;(3)提高了整流元件承受负载的能力,输出电流比三相桥式整流电路增加一倍,适宜于作为低电压、大电流整流,整流效率高;(4)整流变压器采用不同的连接方式,可用380V或460V两种电压供电。
操作电路采用交流115V电源供电,电路中串接有过流、过热保护接点和远控操作控制接点3CR,近控时将3CR短接,见图1。
图1 主电路及操作电路原理图·40·焊管·第21卷第3期·1998年5月 1.2 控制调节系统控制调节系统由控制板、触发板和NA —5S 操作箱构成。
按其功能可分为给定、前置放大、综合反馈、电流截止负反馈、主调节器、触发电路和保护电路七大部分。
图2为焊机系统方框图。
图2 焊机系统方框图1.2.1 给定电路给定电路的主要作用是为主调节器提供一个可调的输入信号。
同时整定焊机的最大和最小输出值。
另外,由四个二极管组成的负逻辑或门电路将给定输入电压信号送到保护电路,当给定输入因任一端断线造成电位过低时,保护立即动作,将电源跳开,见图3。
1.2.2 主调节器主调节器是将给定信号和综合反馈信号经差动放大后,产生一个移相控制电压来控制触发脉冲的移相,从而控制了焊机的输出。
同时由模拟开关Q 6控制,在起弧时使移相控制电压最大,将可控硅导通角推到最小,以减少起弧时的冲击(见图4)。
