GTAW (TIG)
3.0 GTAW (TIG) Welding Process
The heat needed for Gas Tungsten Arc Welding is produced by an electric arc maintained between a non‑
consumable tungsten electrode and the workpiece to be welded. The heat‑aected zone (HAZ) molten metal
and the tungsten electrode are all shielded from the atmosphere by a blanket of inert gas typically argon
ran through the TIG torch. An inert gas such as argon is inactive, or deficient in active chemical properties
making it non‑reactive so it does not take from or add anything to the metal. Inert gases like argon and
helium do not chemically react or mix with other types of gases. They have no smell and are transparent,
giving the welder maximum visibility of the arc. In some cases, small amounts of a reactive gas such as
hydrogen can be added to enable faster travel speeds.
The TIG welding process produces extreme temperatures of up to 19,426  C, and the TIG torch contributes
only heat to the workpiece through the tungsten electrode. If some filler metal is needed to perform the
weld, it may be added manually in the same way as it is in the oxyacetylene welding process. There are also
ways to feed the filler metal in automatically by specialist systems.
3.1 Typical TIG Welding Setup
3.2 Advantages of the TIG Welding Process
The biggest advantage of the TIG welding process is that it will weld more metals and metal alloys than any
other type of arc welding process. TIG is used to weld almost all steels including mild steel, stainless steel,
Chromoly, titanium, aluminium, magnesium, copper, brass, bronze, and you can even weld gold. You can
also join dissimilar metals to one another such as stainless to mild steel.

Manual Version 1.3 - June/2017

ALUMTIG 200
ALUMTIG 200
GTAW (TIG)
3.3 Concentrated Arc
The precise nature of the TIG welding arc allows a high level of control of heat input to the metal resulting in
a narrow HAZ (heat‑aected zone). This high concentration of heat is a significant advantage when welding
metals with very high heat conductivity such as aluminium and copper. A narrow HAZ is an advantage
because the base metal has undergone a change due to the very fast heating of the arc and rapid cooling
rate. The HAZ is where the welded joint is the weakest and is the area that is most likely to break under
destructive testing.
3.4 Slag Free
Unlike stick welding, there is no need for flux with TIG. Therefore, there is no slag to obscure vision of the
weld pool. The finished weld also does not have the layer of slag le.
3.5 No Sparks and Spatter
In the TIG welding process, there is no transfer of metal across the arc, so there is no molten globules of
spatter to deal with and no sparks produced if the metal being welded is free of contaminants. TIG is also
very quite compared to stick or MIG welding and the only time any real noise will be present is when using a
pulsed arc, or AC welding is being done.
3.6 No Smoke or Fumes
TIG welding on its own does not produce smoke or dangerous fumes. But if the base metal contains coatings
or elements like lead, zinc, nickel or copper that do produce fumes, these must be dealt with as in any
electric arc welding process. If the workpiece has oil present, paint, grease or other contaminants, harmful
smoke and fumes will always be made as the heat of the process burns them away. It is of the utmost
importance when TIG welding to clean and prepare your meals with diligence.
3.7 TIG Disadvantages
The major disadvantage of the TIG welding process is the slow and low filler metal deposition rate. Another
disadvantage is that the skills needed to accomplish a beautiful sound weld can be diicult to learn, and
requires a good deal of practice to become skilled. The higher amounts of ultraviolet rays from the arc also
causes the formation of ozone and nitrous oxides. Extra care should be taken to protect skin with the proper
PPE with the correct shade welding filter and helmet.
3.8 Process Overview
TIG is a very clean process, and it is a great choice from a welders point of view because of the reasons
above. For an excellent result, it is a must that the welder maintains sound welding conditions by always
properly cleaning the material, using cleaning and using clean filler metal, clean gloves, and ensuring to
keep oil, dirt and other contaminants away from the welding area. Cleanliness is one of the most important
factors with TIG, especially on aluminium and magnesium. These metals are more prone to contaminants
than ferrous metals the porosity in aluminium welds has been known to be caused by hydrogen this is
why it is the most necessary to completely remove hydrogen containing elements such as moisture and
hydrocarbons that reside in the form of oils and paint.

FUNCTION PARAMETERS PURPOSE
1. Pre‑Flow 1‑10 Seconds
(N/A AUTO MODES)
This parameter operates in 2T and 4T HF TIG mode only and is
used to provide gas to the weld zone prior to striking the arc,
once the torch trigger switch has been pressed. This control
is used to dramatically reduce weld porosity at the start of a
weld.
2. Start Amps 10‑200 Amps
(N/A AUTO MODES)
(N/A FOOT CONTROL)
This parameter is used to set the start current for TIG. In 4T
mode the Initial Current remains on until the torch trigger
switch is released aer it has been depressed. In 2T mode this
is the Initial Current for the Up Slope current ramp.
3. Upslope 0‑10 Seconds
(N/A AUTO MODES)
This parameter is used to set the time for the weld current to
ramp up from INITIAL current to BASE current. (N/A AUTO MODES)
(N/A FOOT PEDAL)
4. Welding Amps 10‑200 Amps
(N/A AUTO MODES)
This parameter sets the welding current. In PULSE TIG mode,
this parameter sets the PEAK current. (N/A AUTO MODES)
5. Pulse Base Amps 10‑200 Amps
(N/A AUTO MODES)
This parameter sets the welding current. In PULSE TIG mode,
this parameter sets the BASE current. (N/A AUTO MODES)
6. Downslope 0‑10 Seconds
(N/A AUTO MODES)
Down Slope will ramp amps “down” from the welding amp
value to the end amp value to give time to fill the crater le
at the end of the weld bead. Can also be used in the 4T mode
to help with heat control by briefly tapping the switch to cool
o the weld before tapping it again to restart the up slope
sequence before the arc reaches the end amp stage.
7. End Amps 10‑200 Amps
(N/A AUTO MODES)
Sets the final or minimum current before the arc is
terminated. Used for filling craters at the ends of the weld and
crack prevention.

FUNCTION PARAMETERS PURPOSE
8. Post‑Flow 1‑10 Seconds
(N/A AUTO MODES)
Controls the amount of time in seconds that the argon flows
aer the arc has terminated. Provides proper shielding
during cooling to prevent rapid oxidation of the weld which
results in porosity the weld pool.
9. Pulse Peak Amps 10‑200 Amps
(N/A AUTO MODES)
This displays the parameter.
10. Pulse Base Amps 10‑200 Amps
(N/A AUTO MODES)
This displays the parameter.
11. Pulse Time On
(Balance) %
10‑90%
(N/A AUTO MODES)
Defines the duty cycle (balance) of the pulse, by dividing or
skewing the amount of time the pulse stays in the lower or
upper stage of the pulse. The pulse consists of two stages:
Welding amps (upper /Peak) and Pulse amps (lower/
background current). This is represented by a % of total
time the pulse spends in the pulse amp stage of the cycle
during one full pulse. The feature can be used to increase or
decrease pulse amp time relative to the welding amp time of
the cycle to help manage heat input.
12. Pulse Frequency
Hertz (Pulses per
second )
1‑500Hz
(N/A AUTO MODES)
Represented by Hertz (Hz), the pulse frequency defines
the actual number of times each second the pulse makes
one complete cycle between welding amps (peak/high
amp value) and pulse amps (background/low amp value).
This is also commonly referred to as Pulses Per Second
(PPS). Low pulse frequencies are ideal for timing the
point where filler metal is added. This helps improve
appearance and uniformity. Higher pulse frequencies are
useful for welding seams and edges of thin material. Also
it is useful for overall heat input control for thicker metals.
Higher pulse frequencies are highly useful for automated
welding processes. WARNING: WELDING AT HIGH PULSE
FREQUENCIES INCREASES THE DECIBEL /NOISE LEVEL OF
THE ARC. HEARING PROTECTION IS HIGHLY RECOMMENDED!

FUNCTION PARAMETERS PURPOSE
13. 2T/4T Selection N/A To operate with the torch switch, select 2T or 4T (2T Double
ended arrow 4T separate arrows). For 2T operation, simply press
and hold the switch. The panel program will cycle automatically.
When the switch is released, the arc will downslope and
terminate with post gas flow. When in 4T mode, the switch is
pressed, and held to start the pre‑flow and the start amps part
of the cycle. When released, upslope be‑gins and continues until
the amps are raised to the preset welding amps. When pressed
and held again, downslope starts and ramps down to the end
amp stage (crater current). When released, the arc terminates,
and post flow begins. If desired, before the downslope finishes,
the switch may be tapped again to start the up slope again.
14. HF or Li TIG
Selection
N/A The Process selector oers the choice of Li Tig (for DC only)
which requires contact with the metal to initiate the arc and
High Frequency Start which allows non contact starting of the
arc (for AC and DC). (HF is selected when symbol is not striked
out) The li start function on the ALUMTIG 200 provides a cold
electrode for safety, and prevents accidental starts. This requires
that the pedal or torch switch must be used to energise the arc.
HF refers to the start type only. The inverter design of the welder
eliminates the need for a constant HF overlay in AC.
15. Welding Current N/A This displays the Amps in real time while welding and will hold
aer weld is complete.
16. AC or DC Selection N/A The unit features AC/DC operation. This machine uses advanced
square wave for AC that has excellent wet in, and arc stability.

FUNCTION PURPOSE
17. AC Balance 50‑98% Defines the percent of Electrode Positive (EP) used during AC welding to
provide cleaning action. This divides the time that the AC cycle spends
in Electrode Positive or Electrode Negative during one full AC cycle. It
controls the amount of cleaning and penetration via a ratio to achieve
the best balance while welding on AC. Too much cleaning action will
result in tungsten balling or splitting. Too little cleaning can result in
dirty, sooty welds and even a dull weld appearance. Simply put, as the
percent increases, greater cleaning will occur, but less penetration will
be achieved. For old aluminium that has some corrosion, adjust the ac
balance to where you use more (EP).
18. AC Frequency 10‑200 Hz Governs the number of times per second that the current alternates in
AC mode. To achieve greater arc focus (constriction) and increase puddle
agitation while welding in AC mode, increase AC frequency. This allows
pinpoint use on thin materials, and helps penetration on thicker materials.
Ideal adjustment range is usually between 80‑120Hertz. For comparison
most transformer welders operate on 60 Hz. Greater arc control and
stability can be achieved through the higher frequency range oered by
this welder. Lower Frequencies will widen and soen the arc and reduce
the level of control. WARNING: INCREASING THE AC FREQUENCY ALSO
INCREASES THE DECIBEL/NOISE LEVEL OF THE AC WELDING ARC. HEARING
PROTECTION SHOULD BE WORN!
