WARNING :
The following wiresareusedinreversepolarity: SDZN= SAFDUALZN.
2.4.POSITIONING THE WIRE
To setup thewire:
Turnthe powersourceoff.
Open the doorof the wire-feederunit [5] and ensurethat it can not fall.
Unscrewthe spoolaxlenut. [6].
Insert thespoolofwireon the axis. Makesurethat the locating pinof theshaft [6] is properly located intothe reellocator.
Screwthespoolnut [6] back on the shaft, turning it inthe direction shownbythe arrow.
Lowerthe leverof wiredriver[9] inordertoreleasethe rollers.
Takethe end of the wireofthe spooland cut thedistortedend piece.
Straighten the first15 centimetersofwire.
Insert thewireviatheinlet wire-guideof the plate.
Lowerthe rollers[9] and raisethe leverinordertoimmobiliseit.
Adjust the pressureofthe rollerson the wiretothe correct tension.
Wirefeed
The wirefeeding button (8)feedsthe wireintothetorch. The wirefeedsover1satminimum speedand the speed increasesgradually until the set
wirespeedis reached,but is limited to12 m/ min. The settingsmaybechange atanytime; thepowersourcedisplays the speed.
To feedthewirethrough thetorch
Maintainthe wirefeeding button (8).
Wirespeed can be adjustedwiththebutton onfront panel.
To full thegas lineor adjustthegas flow
Pushthe gasbleedbutton (9).
2.5. WIRE DRIVERWEAR PART
The wearingpartsof the wiredriver,whoseroleis toguide andadvancethe welding wire, must be adapted tothe type anddiameterofthe welding
wireused. Onthe otherhand,theirwearmayaffect thewelding results. Isnecessarytoreplacethem.
Pleaserefertoparagraph5.5tochoosewearingpartsforwiredriver.
2.6. CONNECTIONOFTHE TORCH
The MIG welding torchis connected tothe front ofthe wirefeeder,afterensuring it hasbeenproperly outfitted withthe wearpartscorresponding to
the wireused forwelding.
Forthis purpose, pleaserefertothetorchinstructions.
2.7.GAS INLETCONNECTION
The gasoutlet is positioned atthe rearof the powersource. Simply connect it tothe pressure-regulatoroutlet ofthe gascylinder.
+Placethe gascylinderon the trolleyat the rearof the powersourceand fasten the bottleusing thestrap.
+Open the cylindervalveslightly toallowexisting impuritiestoescapeand then recloseit.
+Mount thepressureregulator/flowmeter.
+Open the gascylinder.
During welding, thegasflowrateshouldbe between 10 and20l/min.
WARNING:
Besurethat the gascylinderis properly secured on the trolleybyattachingthe safetystrap.
2.8.SWITCH ON
The mainswitchis located at therearof the powersource.
Flipthis switchtoturnthe machine on.
Note:Thisswitchmustnever beflippedduringwelding.
