PULSED TIG
Conventional Pulsed TIG 
Typically from 0.2 to 10 PPS. Provides a heating and cooling effect on the weld puddle and can reduce distortion by lowering the average amperage. This heating and cooling effect also produces a distinct ripple pattern in the weld bead. The relationship between pulse frequency and travel speed determines the distance between the ripples. Slow pulsing can also be coordinated with filler metal addition and can increase overall control of the weld puddle.
High Speed Pulsed TIG 
In excess of 40 PPS, Pulsed TIG becomes more audible than visible—causing increased puddle agitation for a better as-welded microstructure. Pulsing the weld current at high speeds — between a high Peak and a low Background amperage — can also constrict and focus the arc. This results in maximum arc stability, increased penetration and increased travel speeds.
AC waveshape
Standard Square Wave
The Standard Square Wave offers fast transitions between EN and EP for a responsive, dynamic, and focused arc with better directional control. It forms a fast-freezing puddle with deep penetration and fast travel speeds.
Sine Wave
The Sine Wave a soft arc with the feel of a conventional power source. It provides good wetting action and actually sounds quieter than other waves. Its fast transition through the zero amperage point also eliminates the need for continuous high frequency.
MIX TIG CONTROL
Features of MIX TIG:
The AC current can get a very good clearance, and DC current can get a deeper penetration.
Use the MIX TIG we can get an excellent Arc Concentration,can be carried out the excellent welding performance from thin to thick plate.
1) Nice weld appearance, deep penetration.
2) Excellet Arc Concentration..
3) Substantially reduce the electrode consumption.
MIX TIG Frequency (Hz):
the cycle time of MIX
TIG in 1 second. Adjustable range: 0.1-10Hz.
MIX TIG Balance (DC) %:
DC Balance (%) = (tad/Tmix) x 100
