 WARNING! Risk induced by the arc: Arc rays can burn eyes and injure skin.

9  Useweldinghelmetwithcorrectshadeoflter.Wearcompletebodyprotection.

 WARNING!Riskinducedbyelectromagneticelds:Weldingcurrentproduceselectromagneticeld.

8 DO NOTusewithmedicalimplants.Nevercoilweldingcablesaroundyourbody.Routetheweldingcablestogether.

9 The operator should be properly trained to use the welder safely and should be informed about the risks relating to MIG and ARC welding

procedures, the associated protection measures and emergency procedures.

▲ DANGER!Unplugthewelderfromthemainspowersupplybeforeperformingmaintenanceorservice.

9  Keepthewelderandcablesingoodworkingorderandcondition.(Takeimmediateactiontorepairorreplacedamagedparts).

9  Usegenuinepartsandaccessoriesonly.(Nonrecommendedpartsmaybedangerousandwillinvalidatethewarranty).

9 Use an air hose to regularly blow out any dirt from the liner and keep the welder clean for best and safest performance.

9  Checkandspraythegascupandcontacttipregularlywithanti-spattersprayavailablefromyourSealeystockist.

9  Locatewelderinadequateworkingareaforitsfunction.Ensureareahasadequateventilationasweldingfumesareharmful.

9 Keep working area clean, tidy and free from unrelated materials. Also ensure the working area has adequate lighting, and that a fire

extinguisher is at hand.

5.1. SHORT CIRCUIT PROTECTION

5.1.1. Whenashortcircuitisdetected,themachinewillturno󰀨theoutputcurrenttoavoidbeinginahighcurrentoutputstateallthetime.

 Sometimestheoutputcurrentmaystillexist,andtheusershouldavoidshortcircuitbetweentheelectrodeandtheworkpieceasmuch

5.2.2. 2T/4TWORKINGMETHODS

5.3. PRE GAS AND POST GAS

5.3.1. Beforestartingtheweldingwork,closetheweldingtorch,andthemachinewillbegintodelivergas,whichisthepregas.Thefrontair

 supplyensuresthattheweldingisinaprotectivegasatmosphereandimprovestheweldingquality.

 Aftertheendofthewelding,donotimmediatelyremovethetorch,thetorchcontinuestotransportasectionofgas,whichhelpsto

 reducethetemperatureoftheweldmentsurface,butalsotoavoidthehigh-temperatureworkpieceandairchemicalreaction.

5.4. SYN—JUST FOR MIG/MAG

5.4.1. SYN means synergy. The essence of synergy is that after testing, we get suitable welding parameters, and write it into the software,

when you need to query welding parameters, you do not need to ask and query, only need to select certain parameters on the panel,

 andtheweldingmachinewillrecommendtheappropriateweldingcurrent(andweldingvoltage).

5.4.2. However,everyone’sfeelandthespeedoftheweldingmachinevary,soalthoughwerecommendthecurrent(andvoltage),youcan

 stilladjustonthisbasis,onlynetuningisrecommended.

5.5. MMA (ARC FORCE)

5.5.1. When the electrode is too close to the workpiece, the machine will increase the output current. The electrode will melt faster.

5.5.2. ARCFORCEhelpspreventshortcircuits.

5.6. MIG/MAG (INDUCTANCE)

5.6.1. Thehardnessofweldingarccanbechangedbyadjustingtheinductance.Thesmallertheinductancevalueis,theharderthewelding

 arcisandthebiggerthesplashis.Thehighertheinductancevalue,thesofterthearcandthesmallerthesplash.

5.7. WELDING PROCEDURE

5.7.1. Specify the material to be welded, the thickness, and the welding mode to be used.

5.7.2. Selectappropriatetoolingformodetobeused(Section5).

5.7.3. Connectthepowerline,gas,wireorelectrodeandwelding/cuttingtorch,andturnon(seeFig.1,Fig.2,Fig.3,Fig.4)

5.7.4. Select the appropriate mode on the screen.

5.7.6. Determinetheprocesstobeusedwhenwelding,suchas4Tmode,pulse,etc.

5.7.7. Start welding or cutting.

5.7.8. Duringtheweldingprocess,thecurrentorvoltage,wirefeedspeedandprocessparameterscanbeadjustedaccordingtothe 

 weldinge󰀨ectuntilasatisfactoryweldinge󰀨ectisobtained.

5.7.9. Forthemachinewithpostgasfunction,whentheweldingworkisnished,theweldingtorchshouldnotleavetheworkpiece 

immediately, and the post gas should be completed.

5.8.1. Thediameteroftheweldingwire,thediameterwirefeedwheelandthediameteroftheconductivenozzleshouldbethesame.

5.8.2. Thenozzleattheheadofthetorchplaysaprotectiverolefortheconductivenozzle,andconfirmthatithasbeeninstalledbeforewelding.

9 Inspect the welding cables regularly for any damage or wear and tear. Replace any cables that show signs of damage, such as fraying, s,

or cracks.

9 Check the consumables, such as tips, nozzles, and electrodes, regularly for wear and tear. Replace any consumables that are damaged

 orwornout.Usingdamagedconsumablescannegativelyaffectthequalityofyourwelds.

9 Check the gas cylinder regularly for pressure and leaks. Replace the gas cylinder if it is empty or damaged.

9  Whennotinuse,storeyourweldingequipmentinaclean,dry,andsafelocation.Keeptheequipmentcoveredtoprotectitfromdust,
