4. ARC WELDING PROCESS CYCLE - TIG DC 2T
The function of a button to control the welding handle, the welder has a non-contact arc ignition
module (oscillator), with a built-in gas supply valve. When the control button on the handle is
pressed, the control signal is sent to the welding machine's controller, which develops a gas preflow
function to clean the weld area before welding, and with a delay, it sends a signal to the source which
delivers an impulse to the non-contact arc ignition system, which produces a high-voltage impulse to
initiate the welding process, and then determines the time for the current to rise to the preset welding
current. After this, all other functions will be carried out (we will discuss them below) according to
the welding cycle. When the button is released, the welding current will decrease linearly, the arc will
start to expire and the welding area will be cleaned with gas (Postflow), the gas supply valve will be
closed with a delay. TIG welding, both direct and alternating current, stands out among other ways
by its rather complicated additional settings.
Figure 1 Welding cycle ladder - 2-tact button mode

13 | Pag e PATON®ADI 200 PAC AC/DC TIG/MMA
4.1 ARC WELDING CYCLE - TIG DC 4T
The function of a button to control the welding handle, the welder has a non-contact arc ignition
module (oscillator), with a built-in gas supply valve. When the control button on the handle is
pressed, the control signal is transmitted to the welding device controller, similar to the TIG - 2T
function (see point 4.), but with two differences.
The first difference - as long as we keep the button pressed for the first time, the weld area will be
preflushed with gas (Preflow) as well as providing an impulse to the non-contact arc ignition
system, which produces a high voltage impulse initiating the welding process with the initial current
(Start Current), only when the button is released will the welding current increase to a fixed value
of working current (Main Current).
Second difference - at the end of welding, when the button in the handle is pressed again, the
welding current will decrease linearly to the value of the crater filling current (Low current) as long
as the button is pressed, the current will be constant. When the button is released, the welding current
will decrease again linearly (Finish Current), the arc will start to expire and the welding area will be
purged with gas (Postflow), the gas supply valve will close with a delay.

14 | Pag e PATON®ADI 200 PAC AC/DC TIG/MMA
4.2 PRE-WELDING GAS PURGING
This function is necessary to protect the welded area from the harmful effects of atmospheric air and
consists in pre-cleaning the welded area with shielding gas against electric arcing. By default, the
blowing time [Pre Flow] is set to 1.0s, this value can be changed at any time at your discretion.
The mode for changing the value of any function in the current welding method, see section 8.2.
4.3 INITIAL CURRENT (PILOT ARC CURRENT) SETTING
This function facilitates the welding process by means of a welding handle when the arc ignition is
activated. It allows the welding process to start at low current values, which only sustains the cycle
without increasing the heat input to the weld and without burning the material. When welding in inert
gas shielding with the TIG - 4T function, it is sensible to heat up the welded area. The default value
of the initial current [Start Current] is 40 A
.
The mode for changing the value of any function in the current welding method, see section 8.2.
4.4 LINEAR INCREASE OF WELDING CURRENT
This function saves electrode wear, extends the life of the welding torch and facilitates its use. It
eliminates the formation of initial spatter of metal melted in the weld pool. In addition, during the
[Rise Time] period of the linear increase in welding current, the welding fixture can be positioned
exactly in the welding area because the initial point of the pre-arc is not always in the welding area.
The place of the weld area can also be preheated. By default, the period for which the welding
current is continuously rising is set to 1.0 seconds.
The mode for changing the value of any function in the current welding method, see section 8.2.

15 | Pag e PATON®ADI 200 PAC AC/DC TIG/MMA
4.5 LINEAR DECREASE OF WELDING CURRENT
This function is necessary to improve the crater filling process, which is created under the pressure of
the basic working current of the welding arc. The crater left at the end of the weld is a very serious
defect in the weld, which can cause the whole seam to crack or leak and is then a source of defects in
the weld. Therefore, it is much easier and more correct to perform a weld for a fixed time of the
current [Fall Time]. The default setting is 0.1 s.
The mode for changing the value of any function in the current welding method, see section 8.2.
4.6 CRATER WELDING CURRENT
It is essential to determine the level to which the current drops at the end of the welding process. It is
necessary to fill the crater in the case of the TIG-4T button mode (while holding the handle button
for the second time). By default, the crater filling current [Finish Current] is set to 10 A.
The mode for changing the value of any function in the current welding method, see section 8.2.
4.7 ARC STABILIZER FUNCTION
This function consists in maintaining the glow of the arc by the oscillator during the entire welding
process, when the arc is broken, the oscillator will ignite it again. It is recommended to use this
function at low currents.
The mode for changing the value of any function in the current welding method, see section 8.2.

16 | Pag e PATON®ADI 200 PAC AC/DC TIG/MMA
4.8 POST WELDING GAS PURGING
According to this function, the area to be welded is cleaned with protective gas immediately after
welding. This is to prevent the molten metal in the welded area from contact with atmospheric air. By
default, the final cleaning period [Post Flow] is 2.5 s and can be adjusted as desired.
The mode for changing the value of any function in the current welding method, see section 8.2.
4.9 PULSED CURRENT WELDING FUNCTION - TIG DC
This function is intended to facilitate control of the welding process in spatial positions as well as the
welding of non-ferrous metals. Influencing takes place directly on the mixing of molten weld metal
and this, in turn, on the stability of weld training. The correct setting of the parameters of the
pulsating current welding process has a direct effect on the quality of a welded joint, in particular, it
reduces the porosity and fineness of the weld metal grains, thus increasing the quality of the joint.
To activate this function in the device, two parameters must be indicated: pulse balance [Pulse
Balance], pulse frequency [Pulse Frequency].
The mode for changing the value of any function in the current welding method, see section 8.2.

on). For function value change mode, see section 8.2.

5. TIG AC ARC WELDING WITH FUNCTION - TIG AC
5.1 ARC WELDING CYCLE - TIG AC 2T
The function of a button to control the welding handle, the welder has a non-contact arc ignition
module (oscillator), with a built-in gas supply valve. When the control button on the handle is
pressed, the control signal is sent to the welding device controller, which activates the gas preflow
function to clean the weld area before welding. It then sends a signal to the source, which supplies an
impulse to the contactless arc ignition system, which produces a high voltage impulse to initiate the
welding process, and then determines the time for the current to rise to the preset welding current.
After this, all other functions will be carried out (we will discuss them below) according to the
welding cycle. When the button is released, the welding current will decrease linearly, the arc will
start to expire and the welding area will be cleaned with gas (Postflow), the gas supply valve will be
closed with a delay. TIG welding, both direct and alternating current, stands out among other ways
by its rather complicated additional settings.

5.1.2 ARC WELDING CYCLE - TIG AC 4T
The function of a button to control the welding handle, the welder has a non-contact arc ignition
module (oscillator), with a built-in gas supply valve. When the control button on the handle is
pressed, the control signal is transmitted to the welding device controller, similar to the TIG - 2T
function (see point 5.0), but with two differences.
The first difference - as long as we keep the button pressed for the first time, the weld area will be
preflushed with gas (Preflow) as well as providing an impulse to the non-contact arc ignition
system, which produces a high voltage impulse initiating the welding process with the initial current
(Start Current), only when the button is released will the welding current increase to a fixed value
of working current (Main Current).
Second difference - at the end of welding, when the button in the handle is pressed again, the
welding current will decrease linearly to the value of the crater filling current (Low current) as long
as the button is pressed, the current will be constant. When the button is released, the welding current
will decrease again linearly (Finish Current), the arc will start to expire and the welding area will be
purged with gas (Postflow), the gas supply valve will close with a delay.
