1.1 INTRODUCTION
Discovery221AC/DCEvoisanadvancedtechnologysingle-phaseweldingpowersourceforACand
DCTIGweldingoperations.
Discovery300AC/DCEvoisanadvancedtechnologythree-phaseweldingpowersourceforACand
DCTIGweldingoperations.
ACTIGfunctionsareidealforaluminium,magnesiumandrelatedalloyswelding.
Mildsteel,stainlesssteelandcoppercanbeeasilyweldedinDCTIG.
ACTIGweldingisoptimizedthanksto:
Synergic arc strike can be selected by the user interface according to tungsten electrode diameter.
ExtrafusionfunctionmaximizesarcfocusingforconsiderablethinmaterialinACTIGwelding.
Mixed AC/DC increases arc penetration for thick aluminium plates.
PulsedACTIGmodewhichpreventstheriskofdeformationoftheworkpieceinthecaseofprolonged
weldingoperations.
Upto4,00mmdiameterelectrodeweldingispossibleinMMA.
Thefanisturnedononlyduringwelding,attheendoftheweldingprocessitremainsonforaxed
periodoftimeaccordingtoweldingconditions.
Thefanisnonethelesscontrolledbyspecicthermalsensorsthatguaranteeacorrectcoolingofthe
machine.
Accessories/ancillary devices that can be connected to the unit:
- manualremotecontrolforremoteadjustmentoftheweldingcurrent.
- foot-pedalremotecontrolforTIGtorcharcstrikingandremoteadjustmentofweldingcurrent.
- UP/DOWNtorchortorchwithpotentiometer.
- liquid cooler for TIG torches.
Consultyourdealerforanupdatedlistofaccessoriesandthelatestnewproductsavailable.
