INSTALLATIONINSTRUCTION
The machine isequipped withpowervoltagecompensation equipment. When powervoltagefluctuates
between±15%ofratedvoltage, it still can worknormally.
When uselongcable,inordertopreventvoltageformgoingdown,biggersection cableissuggested.If
cableistoo long,itmayaffectthe performanceofthe powersystem.Sowesuggestyou touseconfigured
length.
1. Makesureintakeofthe machine notblocked orcovered, lest coolingsystemcouldnot work.
2. Makegood connectionofshieldedgassource.Gassupplypassageincludescylinder,argon
decompress flowmeterand pipe. Connectingpart ofpipeshouldusehooporotherthingstofasten,
lest argon leaks outandairgetsin.
3. Ground the cableswithsection area no
less than 6mm2tothe housing,the way
isconnectingscrewinthe back ofthe
powersourcetoground device
4. Correctlyconnectthe arctorchorholder
accordingtothesketch.WhenuseMMA
welding:Makesurethe cable,holderand
fasteningplughavebeen connectedwith
theground.Putthefasteningplugintothe
fasteningsocketatthe “-”terminaland
fastenitclockwise.When useTIGwelding:
Putthegas-electricityplugofthe welding
gun tothejointatthe frontpanel,and
fastenclockwise.Puttheairswitchonthe
guntotherelevantjointatthe frontpanel,
andfastenthescrew.
5. Putthefasteningplugofthecableto
fasteningsocket of “+”terminalatthefront panel, fastenitclockwise,andtheearthclampattheother
terminalclampstheworkpiece.
6. Accordingtoinput voltagegrade, connect powercablewithpowersupplyboxofrelevant voltage
grade. Makesurethereisnomistakeand the voltageofpowersupplydoesnot exceed permission
range.. Afterthe abovejob，installation isfinished and weldingisavailable.
WARNING
Beforeconnecting operation please make sureall thepoweristurnedoff.Therightorder
istoconnectthewelding cableand ground cabletothemachinefirst,and make suretheyarefirmly
connectedand thenputthepowerplug tothepowersource.

OPERATIONINSTRUCTION
TIG WELDING DESCRIPTION
1.Turnon the powerswitchoffrontpanel, digitalcurrentmeterisnormal,fan beginstorun.
2.Turnon argon switch, and adjust gaspressuretorated value.(refertoflowtable)
3.Press switchoftorch, electromagneticvalveisstarted. Youwill hearthe soundofelectricity-releasingHF
sparkleand at the sametime, argon getsout the torch. NOTES:Ifthe first timewelding, you should
press switchforafewsecondsbeforewelding, until all the airinthegaspassageisremoved, and then
start toweld.When youstopwelding, argon will still flowout forafewseconds,whichisdesigned to
guarantee that weldspot isprotected beforecoolingdown. Sowhen the electricarcstops, keepthe
weldingposition forawhileand then movethe torch
4.Set suitableweldingcurrent accordingtothe thickness ofworkpieceand process demand.
5.Keep2-4mm spacebetween tungsten poleandworkpiece,presstorchcontrolswitch,between
electrode and workpieceHFelectricityisreleased;Afterarcinitiation ,HFsparkledisappearssoon and
can start towork.
STICKING DESCRIPTION
1.Turnon the powerswitchon the front panel,and the fan beginstowork.
2.Makesurefunction switchoffrontpanelison “down”position thatissticking.When weldingjawnips

NOTES ORPREVENTIVE MEASURES
1.Environment
1）Themachine shouldbeoperatedindryenvironmentswithhumiditylevelsofmax90%.
2）Ambient temperatureshouldbebetween -10 to40degreescentigrade.
3）Avoidweldinginsunshine ordrippings. Donot let waterinfiterthe machine.
4）Avoidweldingindust area ortheenvironmentwithcorrosivegas.
5）Avoidgasweldinginthe environmentwithstrongairflow.
2.Safetynorms
Theweldingmachine isinstalled withprotection circuit ofovervoltage, overcurrent and overheat. When
voltage,outputcurrentandtemperatureofmachine exceed therequired standard,weldingmachine will
stopworkingautomatically.However,overuse(suchasovervoltage)will stillresultindamagetothe
weldingmachine.Toavoidthis, theusermust payattention tothe following.
1）Theworking area isadequatelyventilated
Theweldingmachine ispowerfulmachine, when it isbeingoperated, it generatedbyhighcurrents,
and naturalwind will notsatisfymachine cooldemands.Sothereisafan ininner-machine tocool
downmachine.Makesuretheintakeisnotinblock orcovered,itis0.3meterfromwelding
machine toobjectsofenvironment. Usershouldmakesurethe workingarea isadequately
ventilated. It isimportant forthe performanceand thelongevityofthe machine.
2）Donotoverload
The operatorshouldremembertowatchthe maxdutycurrent(Responsetothe selectedduty
cycle).Keepwelding currentisnotexceed maxdutycyclecurrent.Over-load currentwill damage
and burnupmachine.
3）Noovervoltage
Powervoltagecan befound indiagramofmaintechnicaldata.Automaticcompensation circuitof
voltagewillassurethatweldingcurrentkeepsinallowablerange.Ifpowervoltageisexceeding
allowablerangelimited,it will damagetocomponentsofmachine.The operatorshouldunderstand
thissituation and takepreventivemeasures.
4）Thereisagroundingscrewbehind weldingmachine,withagroundingmarkeron it. Before
operation,weldingcrustmustbegrounded reliablewithcablewhichsection isover6square
millimeter, inordertoprevent fromstaticelectricity, and accidentsbecauseofelectricityleaking.
5）Ifweldingtimeisexceeded dutycyclelimited,weldingmachine will stopworkingforprotection.
Becausemachine isoverheated,temperaturecontrolswitchison “ON position andtheindicator
lightisred.Inthissituation,you donthavetopull theplug, inordertoletthe fan coolthe machine.
When the indicatorlightisoff,and the temperaturegoesdowntothestandardrange,itcanweld
again.

QUESTIONSTO BERUNINTO DURING WELDING
Fittings,weldingmaterials,environmentfactor,supplypowersmaybehavesomethingtodo withwelding.
Usermust trytoimproveweldingenvironment.
A.Black welding spot
——Weldingspot isnot prevented fromoxidizing.Usermaycheck asfollowing:：
1. Makesurethe valveofargon cylinderisopened and itspressureisenough.argon cylindermustbe
filled uptoenoughpressureagainifpressureofcylinderisbelow0.5Mpa .
2. Check ifthe flowmeterisopened and hasenoughflow.Usercan choosedifferentflowaccordingto
weldingcurrentinordertosavegas.Buttoosmall flowmaybecauseblack weldingspotbecause
preventivegasistooshorttocoverweldingspot.Wesuggestthatflowofargon mustbekeptmin
3L/min.
3. Check iftorchisinblock.
4. Ifgascircuit isnot air-tight orgasisnot purecan lowerweldingquality.
5. Ifairisflowingpowerfullyinweldingenvironment , that can lowerweldingquality.
B.Arc-striking isdifficultand easytopause
1. Makesurequalityoftungstenelectrodeishigh.
2. Grind end ofthe tungsten electrodetotaper.Iftungsten electrode isnot grinded , that will bedifficult to
strikearcand causeunstablearc.
C.Outputcurrentnottoratedvalue
When powervoltagedepartsfromthe ratedvalue,it willmaketheoutput currentnot matched withrated
value;When voltageislowerthan rated value, the maxoutput maylowerthan ratedvalue.
D.Currentisnotstabilizing whenmachineisbeing operated
It hassomethingwithfactorsasfollowing:
1.Electricwirenet voltagehasbeenchanged.
2.Thereisharmfulinterferencefromelectricwirenet orotherequipment.
E.Whenuse MMAwelding ,too muchspatter
1.Maybecurrent istoo bigand sticksdiameteristoo small；
2.Outputterminalpolarityconnection iswrong,itshouldapplythe oppositepolarityatthe normaltechnics,
whichmeansthatthe stick shouldbeconnected withthe negativepolarityofpowersource,and work
pieceshouldbeconnectedwiththe positivepolarity. Sopleasechangethe polarity.

MAINTENANCE
WARNING：
Powermustbeturnedoffforall checking and maintenance, before
opening thehousing,make surethepowerplug isdisconnected.
1.Removedustbydryandclean compressed airregularly,ifweldingmachine isoperated inenvironment
whereispolluted withsmokesand polluted air, the machine need removedust everymonth.
2.Pressureofcompressed airmustbeinside the reasonablearrangementinordertopreventdamagingto
small componentsofinner-machine.
3.Check internalcircuitofweldingmachine regularlyand makesurethe cable.Circuitisconnected
correctlyandconnectorsareconnectedtightly(especiallyinsert connectorandcomponents). Ifscaleand
loosearefound, pleasegiveagood polishtothem, then connectthemagaintightly.
4.Avoidwaterand steamenterintoinner-machine,ifthementerintomachine,pleasedryinner-machine
then check insulationofmachine.
5.Ifweldingmachine will notbeoperated forlongtime,itmustbeputintopackingboxand stored indry
environment.
