TIG AC - Setting the 4-STROKE function
The function indicates how the welding process is activated. In this mode, it
is necessary to press the control button, which sends a signal to activate the
welding process. The PRE GAS function is then activated, followed by START
CURRENT. When the button is released, the welding process starts by swit-
ching to WELDING CURRENT and activating other active functions gradually.
To complete the welding process, press the control button again to activate
the DOWN SLOPE function and then the END CURRENT function. When the
button is released, the welding process ends and the POST GAS function is
activated.

TIG AC - Setting the PULSE function
Setting the value determines the lower welding current I
2
of the pulse. Acti-
vating this function reduces the thermal load on the welded material. Acti-
vation is performed by pressing the control n-coder one after the other.

TIG AC - Setting the DUTY CYCLE function
The function allows you to set the ratio between the main welding current
and the pulse current I
2
. Decreasing the pulse current value causes a decrease
thermal load of the welded material and its penetration.

TIG AC - Setting the FREQUENCE PULSE function
The function allows setting the frequency of the main welding current and the
lower pulse current I
2
. Increasing the pulse frequency reduces the thermal de-
formation of the material and narrows the weld bath. Activation is performed
by pressing the control n-coder one after the other.
