2. Installation
1 TIG welding machines are tted with auxiliary power system, so if 15% of the voltage-
la pipe, it still works.
If you use a long wire to the battery voltage drops, it is recommended to increase the
diameter, but if line too long can cause abnormal operation, so choose the correct
length. Ventilation openings to allow free cooling system to operate.
2 Connect the inert gas source. The system includes a gas cylinder, gas regulator and
gas hose, hose clamps should be AWIhtened, to prevent escape of gas or air from
entering.
3 Motor housing is grounded at least 6mm ² conductors, grounding screw on the back
of the machine over to the grounding system.

Transmission options:
- If switch is set to “TIG”, you can work with TIG DC and AC/DC welding mode.
- DC / AC/DC Switch: “AC/DC” , there is alternate current and aluminum welding
mode.
- 2T/4T button: “2T” n is short welding, pressing button will power up when released, stop
power supply. The rst is the power button is pressed “4T” was and will remain so until
the next time you press the button.
- Pulse on / off: DC TIG pulse mode switch was turned on, then set the pulse parameters
necessary to achieve the required weld efciency.
Controller:
- Pre-ow timer : To ensure the efciency of welding , gas must ow before the ow , this
switch controls the time between the gas and electricity.
- Peak current control : Controls the pulse peak current of
- Clean width area (AC balance):
The reverse polarity connections advantage that the high density , high-volume ar-
gon ions collide with the surface of the object and is situated therein and any oxide
nitridhártyát evaporators . In this case, not only an argon protective effect , but also
cleaning effect. Within a pulse cycle rate can be set in this section .
This button sets the ratio between positive and negative current time direction . When
it is centered, is 50 % , maximum 80%, minimum 20%. If a clockwise direction , positive
current time is extended , reduced to negative and vice versa.
Strong power , cleaning time as low . : 200A , ≤ 30%
Low power , high cleaning time eg . 100A , ≥ 50%

- Down slope control : After completion of welding , the power should be reduced
gradually halt , this switch controls the decay time of the current. If a footswitch is
used, this key is “ 0” , adjustable by turning counterclockwise .
- After-ow time control : Due to the workpiece thermal oxidised , so be cool about gas
welder . To 10s , this button controls the after-ow time .
- Arc force control: MMA mode when the arc length varies, the voltage is changing
and at some point reach a critical value, when the strength of the arch is not ap-
propriate to maintain the melt. Then suddenly the automatic increases or decreases
the current is enough to maintain the melt. The controller can change the intensity
of control.
- Base current control : DC TIG pulses , this button controls the volume of stream valleys
- Pulse frequency control: If DC TIG PULSE position , the button sets the pulse frequency
( 0.5 to 300 Hz )
- Pulse time control: The length of each stage of the pulse cycle is controlled by set-
ting this function. It means that you can make the high amp stage of the pulse cycle
longer or shorter than the low amps stage of the pulse cycle. Each half cycle doesn’t
have to be balanced…it can be skewed to achieve the best result between melting
and freezing. Even though the pulse is happening several times a second, each half
phase of the pulse can be metered to give optimum results.
Indicators Features:
Indicators Overheating protection: If your work for a long time under heavy current,
internal parts are burned due to overheating. To prevent this, it is the light that, when
lit, stop the work, but do not turn it off, so after 2-3 minutes you can continue welding.
Abnormality indicator: Lights when abnormality is in use, so be sure to turn off the ma-
chine and reboot to check the operation. If you continue to behave abnormally,
contact your service technician or manufacturer.

4-2 . Safety requirements
Welding provides protection against overvoltage / overcurrent / overheating. If any
of the above events occurs, the machine stops automatically. However, over-
stress damage to the machine , keep the following guidelines :
1. Ventilation . When welding a strong current going through the machine , so the
machine is not enough natural ventilation for cooling . The need to ensure ad-
equate cooling, so the distance between the plane and any object around it at
least 30 cm . Good ventilation is important to normal function and service life of the
machine.
2. Continuously , the welding current does not exceed the maximum allowable value.
Current overload may shorten its life or damage to the machine .
3. Surge banned ! Observance of tension range follow the main parameter table .
Welding machine automatically compensates for voltage , allowing the voltage
within permissible limits of law. If input voltages exceed the specied value , dam-
aged parts of the machine .
4. The machine must be grounded! If you are operating in a standard, grounded
AC pipeline in the event of grounding is provided automatically . If you have a
generator or foreign , unfamiliar , non-grounded power supply using the machine
, the machine is required for grounding connection point earth to protect against
electric shock .
5. Suddenly stopping may be during welding when an overload occurs or the ma-
chine overheats . In this case, do not restart the computer , do not try to work with
it right away, but do not turn off the power switch , so you can leave in accord-
ance with the built-in fan to cool the welding machines .
5. Maintenance
1. Remove power unit before maintenance or repair!
2. Ensure that proper grounding!
3. Make sure that the internal gas and electricity connections are perfect and
AWIhten, adjust if necessary, if there is oxidation, remove it with sandpaper and
then reconnect the cable.
4. Hands, hair, loose clothing should be kept away under electric parts, such as wires,
fan.
5. Regularly dust from the machine clean, dry compressed air, a lot of smoke and pol-
luted air to clean the machine every day!
6. The gas pressure is correct not to damage components of the machine.
7. If water would be, for example. rain, dry it in the machine and check the insulation
properly! Only if everything is all right, go after the welding!
8 When not in use for a long time, in the original packaging in a dry place.
