In AC square wave TIG welding, the pre-flow time and post-flow time are the same with those in DC TIG welding, and others
are described as below.
• Initial current (I0), welding current (I1) & pilot arc current (I2): The preset value of the three parameters is
approximately the absolute average of the practical welding current, and can be adjusted according to users’ technical
requirements.
• Pulse frequency (1/tp): It can be adjusted according to users’ technical requirements.
• Cleaning strength (100%*Tc/Tp): Generally, in AC welding, when taking the electrode as anode, the current is
called cathode current. Its main function is to break up the oxidized layer of the workpiece, and the cleaning strength is the
percentage cathode current holding in the AC period. This parameter is 10~40% commonly. When the value is smaller,
arc is concentrative, molten pool is narrow and deep, and when it is bigger, arc is dispersive, molten pool is wide and
shallow.

AC pulsed TIG welding is almost the same as AC square wave TIG welding, and what makes them
different is that in AC pulsed TIG welding, the welding current varies with the pulse and peak current and
base current are generated because the welding current is controlled by a low frequency pulse. The
preset peak current and base current are the low frequency pulse peak value (average value) and base
value (average value) respectively. For the AC square wave parameter selecting and setting, please
refer to the corresponding contents in AC square wave TIG welding. For the pulse frequency and pulse
duration ratio, users may refer to the corresponding contents in DC pulsed TIG welding. The pulse
frequency (1/T) is a little low, and it can be adjusted between 0.5Hz and 5Hz. The pulse duration ratio
(Tp/T) can be adjusted between 10% and 90%.
10.5 TIG operation mode
TIG operation mode is a kind of special stipulation, which stipulates the modes to control welding
current through different operation of the torch trigger in TIG (DC TIG, pulsed TIG and AC TIG) welding.
The introduction of TIG operation mode strengthens the application of remote control function of the
torch trigger, so that users can get practical remote controls for welding machines without further
investment.
TIG operation mode should be selected according to users’ technical requirements and operating
habits. All the TIG operation modes for this machine are listed in the table TIG operation modes below.
