1. INTRODUCTION
"AW
ManualMetalArc Welding is a process where anarc is struckbetween a flux-coated
consumabtes electrode and the work piece. The arc and the weld pod are both shielded
by gassesgenerated by the flux coatingof the electrode.
The VORTEX
DX1'3 has beendesigned to be used with 2.Qmm,2.5mmand 3.2mm
diameter electrodes.The smaller are usedwhen welding at lower currents, such as sheet
metalapplications.Increasingtheelectrodediameterpermitshigherweldingcurrentsto
be selected.
WIA manufactures a wide range of mild steel and special purpose electrodes which
cater for homeworkshop, rural, and industrial requirements.SomepopularAUSTARC
electrodes are listed below.
The correctly selected AUSTARC electrode used in
conjunction with your new VORTEX
DX13 will influence the quality of the weld, and the
stability of the arc.
Austarc IZP, Classification E41 12.
A popular general purpose electrodeusedwith ease in all positions, vertical up
ordown. The smoothforcefularemakes it an ideal electrode for
all general
mild steel applications.
Austarc 13S, Classification E41 13.
A smooth running electrodewith a soft arc, particularly suited to light
sheetmetal and smooth mitrefillet welds.
Austarc 16TC, Classification E4816.
A lowhydrogen electrode with good arc stability and out-of-positionwelding
characteristics. This electrode is ideal formedium carbon steels, or steels of
unknownanalysis.
Unicord
A hightensile (50tsi), chromiumnickel electrode specially formulated forjoining
all alloy steelsand irons, and fortool and die maintenance.
GTAW
Gas Tungsten Arc Welding is a welding process where the arc is struck between a
non-consumabletungsten electrode and the work piece. A ceramic nozzle surrounds the
tungsten electrode and directs a flow of inert gas, usually Argon, over the electrode and
the weld zone.
If filler metal is required, it is handfed into the welding arc. The DC current
of the VORTEX
DX13 is suitable for welding most ferrous and non-ferrous metals, but is
not suitablefor welding Aluminiumfor which anAC machine isrequired.

IMPORTANT NOTICE
WARRANTY MAY BE VOIDED IF EQUIPMENT IS POWERED FROM AN ENGINE
DRIVEN GENERATOR.
This equipment may be damaged if it is powered from a low capacity engine driven
generator. Generators less than l6kva may have inadequate voltage control
in this

5. CONNECTION TO ELECTRICAL MAINS POWER SUPPLY
The VORTEX DX1 3 is supptied with a 3 metre, l5Amp Heavy Duty (30/0.25) PVC
mains power supply cable. This cable must only be connected to a correctly installed 15
AmpGPO(General Purpose Outlet). The plug and GPOare both identified by a wide
Earth pin, whichisintendedtopreventthe plug being inserted into a standard 10 Amp
GPO. If it becomes necessary toreplace the mains power supply cable, use only a cable
with equivatent current rating.
The recommendedSupply Fuse rating is
15 Amps.Due to peak current
requirements, theelectrical mains supplyto welding machinesis best protected bya fuse.
If
a circuit breaker is used, it shouldbeof the motor starttype.
If
it is necessary to use an extension power supply cable, ensure that it is rated for a
minimum
of 15Amps. Voltagedrop which will occur over long lengths of cablewill reduce
the maximum welding currentavailablefrom the equipment.
As noted previousy,
it is not recommended that the VORTEX DX13 bepoweredfrom
smallengine-drivengeneratorsets due to the peaksofsupplyvoltagewhichcanoccur
with some equipment
of this type. Excessive voltage peakscan damage the circuits of the
welder.
6. MMAW WELDING
A. CONNECTION FOR MMAW WELDING
It is important to select the electrode polarity in accordance with the manufacturers
recommendations
for that electrode. Mostcommonelectrodes are operatedwiththe
electrode at positive polarity,as illustratedin Figure
2.
FIGURE 2. CONNECTIONS FOR MMAW, ELECTRODE POSITIVE

VORTEX DX13 OWNERS MANUAL Page 7
B. MMAW OPERATION
Be certain that you are wearing suitable protectiveclothing, gloves etc. and that you
are working
in a non-hazardous area. If necessary, refer again to the SAFE PRACTICES
section ofthis manual.
Connectthe Work Clamp to theworkpiece. Place thedesiredelectrode
in the
ElectrodeHolder.Select an appropriateweldingcurrentfortheelectrodediameterby
settingthe knob on the machinefront panel.
WIA AUSTARC electrodeswill give the best
results.
To strike the arc, drag the end of the electrode along the work piece as if striking a
match.
As the arc initiates, lift theelectrode slightly away,aiming to establish anarc
length of approximately3mm.
As the electrode end is consumed, feed theelectrode into thearc in order to
maintain arc length.
As a general rule, the arc should be held as short as possible while
still giving stable burn
off and good weld appearance. An arc which is too long cause an
unwieldy flow
of metal with aroughweld appearanceand reduced penetration.An arc too
short leads
to a narrow weld depositand"stuttery" arc characteristics, andthe electrode is
liable to freeze onto thework piece.
As the solidified weid deposit forms, movethe end of the electrode slowly along the
weld path, aimingto maintaina pool of molten weld metal behind the arc. Decreasingthis
rate of travel
will result in a wider weld deposit, and similarly increasing it will narrow the
weld deposit.
Always fill the crater which tends to form
at the end of a weld deposit, by pausing
momentarily before withdrawingthe electrode to break the arc. Unfilledcraters are a point
of weakness, and canlead to weld cracking.

7. GTAW WELDING
A. CONNECTION FOR GTAW WELDING
For GTAW,the torch is connected electrode negative.Figure 3 illustratesthe correct
connection ofthe welding torch and gas supply.Welding grade Argon isthe shielding gas
most commonlyusedfor
DC GTAWwelding.
Before initial use of the welding torch,
allow gas to purge the torch and hoses for 5
minutes at approximately 10 litres/min. For welding purposes, the gas flow rate should be
set
in the range 2 - 5 litres/min.
Tungsten electrodes for
DC GTAW shouldbe 1 - 2% Thoriated.Thistype will
providethe best arc initiation, arc stability and tip shape retentioncharacteristics.
Thoriated electrodes canbe recognisedby
a red coded end. The tungstenelectrode is
ground to
a point, with the grinding marks pointing towards the tip. For welding currents
less than 28 amps, the includedangle of the point should be 3Q",fOrcurrents greaterthan
20 amps,therecommended angle is 60". When set in thetorch,thetungstenshould
protrudeQmm fromthe ceramic gas
noule.

VORTEX DX13 OWNERS MANUAL Page 9
B. GTAW OPEFIBTION
To initiate thearc,thetungstenelectrodeshould be touchedontotheworkpiece,
then lifted in
a smoothmovementto establish an arclength slightly largerthanthe
diameter
of the electrode.When the arc is stable, it can betransferred to the work piece.
Use
of acopper striking plate is recommended to avoid electrode contamination.
The electrode can also
be contaminatedbycontact with the filler rod. A Contaminated
electrodeproduces an unstable arc.
8. GENERAL MAINTENANCE
Check thatmainssupply is availabte atthe VORTEX DX13 power source,ie.that the
fan is running and the
POWER ON LED is lit. Check for continuity of the welding current
circuit, ie. work lead, workclamp and electrode holder.
The
VORTEX DX13weldingpowersourceincorporates inbuilt protection devices
which will trip if the unit is overloaded. In this event, the machinewill not deliver welding
current, and the red
LED will beilluminated.Ifthethermal overload protectiondevices
havebeen tripped,leavethe machine energised with the fan running to achievethe
maximumcooling rate.
if equipment failure is suspected,forwardthe unit
to yournearest WIA Salesand
Service branch, or aqualified service agent.
