1.1 INTRODUCTION
ThisprofessionalandruggedweldingpowersourceforDCMMAandTIGweldingwithexceptionalarc
characteristicsisdesignedtooperateinharshenvironmentalconditionsintheeldsofprofessional
maintenance,shipyardsando󰀨shore,buildingconstructionandheavyfabrication.
TheARCAIRfunctionallowsperfectde-seamingwithcarbonelectrodesofupto10mmindiameter.
Upto6mmdiameterelectrodeweldingispossibleinMMA.
InMMAweldingtheHotStartandArcForcefunctionsareadjustableandtheyallowimprovedarcstrik-
ing,aatterbeadandmoreuniformweld.
TheAntiStickingfunctionmakesitpossibletodetachtheelectroderapidlyfromtheworkpieceinthe
eventofaccidentalsticking.
Theparameterspre-setintheDCTIGpulsedsynergiccurvesimplifyweldingbyregulationexclusively
of the current.
ThecurrentisadjustablealsofromtheUp-Downtorch.
Thesimplyandintuitiveinterfaceallowshighprecisionadjustmentswith50storableprograms.
Thewiderangeof adjustable pulsed frequency incombinationwiththecomplementaryparameters
(basecurrentanddutycycle)makesitpossibletoweldinslowandfastpulsedmode.
Thankstoitsmodularconguration,thepowersourcecanbeconguredforMIG/MAGweldingbyadd-
ingawirefeedunit,extension,and,ifrequired,acoolingunitandpowersourcetransporttrolley.
Fan. 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:
-UP/DOWNtorchortorchwithpotentiometertoadjusttheweldingcurrentfromadistance.
-Manualremotecontrollerforremoteadjustmentoftheweldingcurrent.
-Foot-pedalremotecontrollerforTIGtorcharcstrikingandremoteadjustmentofweldingcurrent.
 ThemaximumandminimumvalueoftheTIPweldingcurrentcanbesetusingtheremotecontrol

Torch loading
WARNING!
Make sure the torch in use is correctly sized in relation to the welding current required and for
the available and selected cooling type. This prevents the risk of burns to which the operator is
potentially exposed, potential faults, and irreversible damage to the torch and the system.
If a torch is installed or replaced while the unit is running, the circuit of the newly installed torch
must be lled with coolant to avoid the risk of damage to the torch in the case of high voltage arc
strikes without any liquid in the circuit.
