TIG WELDING MODE
1. Connect the ground cable to the connector marked
with a "+" sign and twist the cable plug to secure the
connection.
2. Connect the welding cable to the connector marked
with a "-" sign and twist the cable plug to secure the
connection.
3. Connect the control cable to the socket (IV) and the
burner gas hose to the gas connection (V).
4. Connect the gas hose from the regulator/flow meter
located on the shielding gas cylinder to the gas inlet
on the back of the unit.
4. Now you can connect the power lead and turn the
power on, once the return lead is connected to the
welded element, you can start working.

7. 2T/4T mode
TIG welding (4T Mode)
The starting current and end current can be pre-set. This
feature can compensate for any crater that occurs at the
beginning and end of welding, so 4T is suitable for welding
medium thickness sheets.

Description of individual events in the chart:
• 0: Pressing and holding the torch trigger. The shielding
gas begins to flow;
• 0 ~ t1: Gas pre-flow (0 ~ 2S);
• t1 ~ t2: The arc ignites and the set start current
B
is reached. It lasts as long as the torch trigger is
pressed and held;
• t2: The torch trigger is released. The output current
increases with the welding current;
• t2 ~ t3: The output current rises to the set value. Rise
time can be adjusted;
• t3 ~ t4: The welding process. During this time, the
torch switch is released;
Please note: It is possible to weld using a constant
current value or using the PULSE function.
• t4: The welding gun button is pressed again. The
welding current will start to drop.
• t4 ~ t5: The output current drops to the end current
value. The down-slope time can be adjusted;
• t5 ~ t6: Final current (crater filling current) duration -
depends on how long the torch button is held down;
• t6: Releasing the torch trigger will cause the arc
extinction;
• t6 ~ t7: Post gas flow time. You can adjust this
parameter with in the (0 ~ 10S range);
• t7: End of gas flow and of the welding process.
TIG welding (2T mode)
This function without adjusting the starting current
and crater current is suitable for tack welding, transition
welding, thin plate welding, etc.

Description of individual events in the chart:
• 0: Press and hold the torch trigger. The shielding gas
starts flowing.
• 0 ~ t1: Gas pre-flow (0 ~ 2S).
• t1 ~ t2: The arc ignites and the output current rises
to the set base current (in PULSE mode) or welding
current (if PULSE mode is off).
• t2 ~ t3: The welding process continues when the
torch trigger is pressed and held. If the PULSE mode
is set, the current changes its value cyclically (as in the
diagram). To use the constant current characteristic,
turn off the PULSE mode.
• t3: Releasing the torch trigger causes the welding
current to drop.
• t3 ~ t4: Down-slope time and extinction of the arc.
This parameter can be set in advance.
• t4 ~ t5: Gas post-flow time after arc off depending
on setting (0 ~ 10s).
• t5: End of gas flow and welding process.
Short circuit protection function:
• 1 TIG/DC/LIFT: If the tungsten electrode touches
the workpiece during welding, the current will drop
to 20 A, which will reduce damage to the tungsten
electrode and extend its service life.
• 2 TIG/DC/HF: If the tungsten electrode touches the
workpiece during welding, the current will drop to
0 in 1 s, which will reduce damage to the tungsten
electrode and extend its service life.
• 3 MMA mode: if the rod electrode touches the
workpiece for more than two seconds, the welding
current automatically drops to 0 to protect the
electrode.
• 4 TIG: If the TIG torch button is pressed quickly,
the welding current will decrease by half, another
quick press of the TIG torch button will return to the
previous value of the welding current.
8. OPERATION
1. After connecting the wires as described in the
manual, switch the power switch on the rear panel to
the "ON" position
2. Select the MMA/LIFT TIG/HF TIG welding mode
using the button (4).
MMA mode
3. Set the current appropriate for the electrode used.
4. Touch/tap/rub the end of the electrode against the
workpiece and quickly retract to the required arc
length.
5. The arc will extinguish as the electrode moves away
from the work area.
Lift TIG mode
3. After proper parameterization, open the gas cylinder
valve, the gas valve on the burner and adjust the
required gas flow rate.
4. The arc will ignite when the electrode is rubbed
against the workpiece and lifted by a distance of 2 to
4 mm.
5. The arc will extinguish as the electrode (torch) moves
away from the work area.
HF TIG mode
3. After proper parameterization, open the gas cylinder
valve, the gas valve on the burner and adjust the
required gas flow rate.
4. The arc ignites when the torch is brought closer to
the workpiece.

Please note: When using the HF TIG method, the
ignition spark may interfere with electrical equipment
near the welding machine. Please remember to take
special precautions or use covers.
5. The arc will extinguish as the electrode (torch) moves
away from the work area.
6. Before switching off the power, switch the machine
off using the ON/OFF button on the back of the
machine.
9. DISPOSING OF PACKAGING
The various items used for packaging (cardboard, plastic
straps, polyurethane foam) should be kept, so that the
device can be sent back to the service centre in the best
possible condition in case of any problems!
10. TRANSPORTATION AND STORAGE
Shaking, crashing and turning upside down of the device
should be prevented while it is transported. Store it in a

device. Please contact your customer service to solve the
problem.
What to do in case of a problem?
Please contact your customer service and prepare following
information:
• Invoice number and serial number (the latter is to be
found on the technical plate on the device).
• If relevant, a picture of the damaged, broken or
defective part.
• It will be easier for your customer service clerk to
determine the source of the problem if you give
a detailed and precise description of the matter.
The more detailed your information, the better the
