1. GENERAL PROVISIONS
The PATON ProTIG-200/315-400V AC/DC argon-arc inverter is designed for arc welding:
- TIG AC/DC (constant/variable
current); - ММА (direct current);
- RIV (rivet weld mode).
The best offer for DC and AC welding of a wide range of materials: aluminum, aluminum
alloys (TIG AC mode), parts and materials made of steel, non-ferrous metals and copper
alloys (TIG DC mode). The unit can also be used for welding with coated electrodes (MMA
mode). The inverter provides excellent ignition and a constant and stable arc, highquality
welds and easy operation.
By increasing the frequency of the voltage supplied to the transformer, it is tens of times
smaller, which is why the unit has several times less weight and dimensions with the same
output parameters in comparison with the classic equipment.

5. Pulse function in TIG AC/DC, MMA modes;
6. Increased reliability in dusty environments;
7. Availability of RIV rivet weld;
8. When the temperature reaches 100 ˚C, the power unit will shut down until the
temperature decreases;
9. All electronics in the unit are impregnated with two layers of high-quality varnish,
which ensures the reliability of the product during its entire service life;
10. Infinitely adjustable welding parameters;
11. Stabilization of arc burning in TIG AC/DC modes;
12. Adaptive control of the fan depending on the temperature;
13. The unit has a state-of-the-art digital interface with LCD display, which makes it

4. TIG AC WELDING CYCLOGRAM
Identification marks:
-Тр – purging time before welding.
It is necessary for pre-purging of the welding zone, torch nozzle, and providing
guaranteed protection before arc ignition.
-Іс – start current.
After pre-purge, the arc is ignited at the starting current and during the time Tp it
rises up to lzv. It is used mainly for smooth heating of the edge of the piece so that
there is no melting.
-Tp – current ramp up time.
-Izv – basic welding current. -Тс – decay time.
After welding is complete, the main welding current descends smoothly to Izk for
the time Tc. It is used for crater welding.

PATON ProTIG AC/DC TIG/MMA - 12 -
-Іzk – ending current
-Вр – pulse polarity balance
-Fр – pulse frequency
-Ip – lower pulse welding current
When welding with alternating current, the cyclogram becomes more complicated,
and alternating current parameters are added.
-В – polarity balance.
-F – welding current frequency. In handheld welding machines, it is usually
adjustable from 20Hz to 200Hz.
The AC frequency can be increased or decreased within acceptable limits. This
setting allows the welder to provide more control of the arc by focusing the arc
across the width so that welding in hard-to-reach places is possible. It is used as well
for welding thin materials.

Typical cyclogram of the 2-stroke button mode (TIG АC/2T)
In modern handheld TIG welding torches, there is a button to control the welding
process, which is connected to the device. Consider the two modes of 2-stroke
operation.
There is purging before welding and smooth increase of current to the set value for
the time Tp. After releasing the button, the set current smoothly decreases to the
completion current in the time Ts. Then the purging after welding takes place.
Typical cyclogram of the 4-stroke button mode (TIG АC/4T)
After the button is first pressed and held down, the welding process begins. There
is a pre-welding purge and arc ignition at the start current. The start current will be
maintained until the button is released, after which the start current will smoothly
increase to the set value for the time Tp. After pushing the button again and holding
it, the set current will smoothly decrease to the completion current in the time Ts,
and will remain until the button is released. Then the arc will go out and the post-
welding purge will take place.
The welder chooses the button modes individually depending on the welding
condition.

Example of using the pulse mode:
Turn the machine on, switch to the TIG AC welding mode, set the basic parameters as
follows:
1. "BUTTON MODE" – button mode on the torch, 2Т.
2. "PREFLOW" – pre-purge time, 2 sec.
3. "START CURRENT" – start current, 30 A.
4. "RISE TIME" – current ramp up time, 1 sec.
5. "MAIN CURRENT" – main welding current, 100 A.
6. "FALL TIME" – current decay time, 1 sec.
7. "FINISH CURRENT" – completion current, 30 A.
8. "POSTFLOW" – post-purge time, 5 sec.

9. "PULSE BALANCE" – pulse shape balance, 50 %.
10. "PULSE FREQUENCY" – pulse frequency, 150 Hz.
11. "LOW CURRENT" – lower current (pulse mode), 50 A.
12. "BALANCE" – AC balance, 50 %.
13. "FREQUENCY" – AC frequency, 50 Hz.
Please note! To activate the pulse mode, the parameter "LOW CURRENT" must be
switched from the OFF position to any other value, and the indicator "P" (pulse
mode is on) must light up. Also, the parameter "PULSE FREQUENCY" must be at
least twice as big as the parameter "FREQUENCY". If this is not done, the process
will not be of good quality.
Then the welding can start. The welding arc will oscillate in the amplitude of 100 A to
50 A with the frequency of 150 oscillations per 1 second.
These parameters are set differently in each situation according to the welder's
requirements.

process begins. There is a pre-welding purge and arc ignition at the start current.
The start current will be maintained until the button is released, after which the start

button again and holding it, the set current will smoothly decrease to the completion
current in the time Ts, and will remain until the button is released. Then the arc will
go out and the post-welding purge will take place. The welder chooses the button
modes individually depending on the welding conditions.

Turn the machine on, switch to the TIG DC welding mode, set the basic
parameters as follows:
1. "BUTTON MODE" – button mode on the torch, 2Т.
2. "PREFLOW" – pre-purge time, 2 sec.
3. "START CURRENT" – start current, 30 A.

Please note! To activate the pulse mode, the parameter "LOW CURRENT" must be
switched from the OFF position to any other value, and the indicator "P" (pulse
mode is on) must light up. Then the welding can start. The welding arc will oscillate
in the amplitude of 100 A to 50 A with the frequency of 50 oscillations per 1 second.
These parameters are set differently in each situation according to the welder's
requirements.
RIV welding mode
RIV is a rivet weld or short weld mode.
RIV welding mode is a kind of argon-arc welding with a non-fusible electrode at
direct current. The welding time is permanently fixed by the "pulse time" parameter,
which allows the welder to make many short identical welds.
Consider an example. Let's set the mode:
-peak Current – 100A;
-postflow – 2 sec; - preflow – 2 sec;
-pulse time – 3 sec.
Put the torch to the piece so that the tungsten electrode does not touch the it.
Press the button on the torch. Then:
1. The valve opens and gas comes in. There is a preflow time (preflow) of 2 sec.
2. The arc is ignited at a current (Peak Current) of 100 A.
3. The arc burns exactly the time we set (pulse time) – 3 sec.

- 19 - PATON ProTIG AC/DC TIG/MMA
4. After 3 seconds, the arc goes out.
5. After the arc goes out, there is a postflow time of 2 sec.
The process is finished. To start the process again, press the button on the torch.

2. "PULSE BALANCE" – pulse shape balance, 50 %.
3. "PULSE FREQUENCY" – pulse frequency, 50 Hz.
4. "LOW CURRENT" – lower current (pulse mode), 50 A.
