OPERATION---- PRE-CHECKING--. CIRCUIT DIAGRAM ~~ BLICK DIAGRAM--~ DIAGRAM CIRCUIT--- INSTALLATION&OPERATION--~ABRIEF INTRODUCTION TO THE PRODUCTS TIGACIDC P serial is our newly-developed AC/DC and pulse products, whose main character is thatit can notonly weld stainless steel, alloy steel and carbon steel and other nonferrous metals withDC function, butalso it canweld aluminum andalloy aluminum with ‘AC function. Forinstance, for welding skateboard and bicycle made of aluminum. The total power exchange rateof the machines are over 85%, and they are energy-saving. The main types are AC/DC 200P, AC/DC 250P and AC/DC315P. The use and development of inverter technology in welding benefits from the invention of high power electronic spare parts, esp. !GBT, the employ of which greatly reduces the volume and weight of main parts, e.g. transformer and anti-electricity, thus making our machines able to work under HF 100KHZ. We also employ PWM and CPU- contro! to make the welding current stable, accurate and easy to adjust; and make the machines convenient tooperate, and avoid the disturbance ofelectric magnetism: AC/DC welders are made with invertertechnology, and they arelighter, smarterand more efficient compared with traditional ones; while compared with imported ones, they are cheaper, and has stronger electric net. The most characteristic one is the use of twice inverter technology and output of pure square wave, which makes the arc more straight, heat more concentrating, anti-clearance stronger and wider clearance wider etc to make sure the highquality of themachines. ACIDC P serials are equipped with foot switch, thus liberating the workers' hands, and they can adjust the current with their foot freely. As aresult, at the very beginning or wire-adding, we can speed up the current; while atthe end slowdown the currentin order to form a good welding seam. In a word, the use of foot switch helps raise the welding efficiency and reduces the welding difficulty as well as make sure of the welding quality. If you need pulse welding, we have foot-control switch withthe function of pulse welding. Inverter welders are also equipped with TIG torch, and cable of suitable length, hose and water-cooling connector. Besides, there are also other spare parts for torch, such as ceramic nozzle, collet body, short cap andlong cap. The size and quantity of themcan see in the enclosed packing list. Ifyou need more spare parts, youcan order separately 01 WELDERS. USERS'MANUAL.TIG SERIALCAUTIONS! This equipmentis used mainlyin technology.

USERS'MANUAL.TIG SERIALCAUTIONS &PRE-CAUTIONS Environment 1) The operation shouldbe in acomparative dry environment, the air humidityno more than 90% 2) The around temperature should be between-10C and 40C. 3) Avoid working under the sunor in therain, do notlet in wateror rain . 4) Avoid working under the circumstance of dust orair with corrosive gas. 5) Avoid doing CO2 working underthe condition of strong air flow. 1, Safety tipsTIG welders are equipped with over-voltage and over-currentand over- thermal protection circuit, when the output voltage, output currentand inner temperatureis over the ratedones, the machine will stop working automatically. But over-use (e.g. over- voltage) may damage thewelding machine, sopay attention tothe following tips: 1) Make sure of good ventilationTIG weldersare large technicalwelding machines, and has huge currentthrough it when working, and naturalair flow cannot satisfy its cooling need, so weput two embodiedfans to coolit and makesit work normally. The operator should make sure the fan notblocked or covered, and the distance between the welderand surroundings shouldn't beless than 0.3m. The users should always payattention to the flowing condition ofthe machine, because itis veryimportant for the working quality andworking year ofthe machine. 2) No over-load! The users should pay second attentionto the allowed max loading current (comparative load cycle) , and make surethe welding currentnot surpass the allowed max. Over- current may obviously shorten the working year of themachine, and evenmay fire the machine to pieces. 3] No over-voltage! The power voltageis listed inthe “Main Parameter” table, generally, the automatic compensating circuit may make sure the current is inrated range. Ifthe voltage surpasses the allowed value, the machine maybe damaged. The operator shouldbe familiar withit and take certainactions to preventit . 4) Every welder hasan earth screw, and earth connecting mark. Before operation, please choose a cablewhose section ismore than 6mm2, make the casefirm earth connectingto avoid accidents which may be caused by electricity-leaking . 5) If the working time of thewelder surpasses the standard load cycle, the machine may suddenly enter protection condition and stopworking, which showsthat the machinehas been over thestandard load cycle, and over-heating works the thermal control switch, thus making the machine stop working. Meanwhile, the red pilotiight on the panel board ison. Under this circumstance, you needn't pulloff the plug, so thatthe fan can continue working, thus cooling hemachine. When thered light is off, the temperature decreases tothe standard range, thenyou begin toweld again. WELDERS.

Make sure the power plug ispulled off before you open thecase. 1) Use clearand dry compressedair to removethe dust incertain period, ifthe machine is working under heavy-pollutedenvironment, clear itdaily. : 2) The pressure of thecompressed air shouldbe in asuitable level lestit damages thelittle parts in themachine. 3) Check theinner circuit connectionin the weldingmachine, and makesure the connections are rightand firm (esp. plug-in orparts) ;if there isrust or loose, use the sand-paper to rub off the rust or oxidized coating and re-connectit firmly. 4) Avoid water orwater vapour intothe inner ofthe machine, ifhappens, please firstdn and then measure the Insulation situationwith Omen meter. (including the joints and joint vs case) . Do not continue until you makesure there isno abnormal phenomenon. 5) If themachine is notused for longtime, please putit into the original box andkeep it in dry condition PRE-CHECKING WARNING Blind experiment and uncautious checking may cause trouble for formal repair A\e make the breakdown area bigger. And the inner bare parts of the machine have voltage that may cause dangers if ithas power supply, so any direct or in direct touch may cause accidents of electric shock , and heavy shock may even cause death!
