Pulse TIG Welding
Fig 15 DC Pulse TIG Current Change Waveform
In pulse TIG mode, all DC TIG parameters except current (I3), could check the description above DC TIG Welding. There are 4 dif-
ferent adjustable parameters in this process. Describe them as below.
Ÿ Peak Current (Ip): It should be adjusted according to users' technical requirements.
Ÿ Background Current (Ib): It should be adjusted according to users' technical requirements.
Ÿ Pulsed Frequency (1/T): T=Tp+Tb. It should be adjusted according to users' technical requirements.
Ÿ Pulse Duration Ratio (Pulse Width (100%*Tp/T): The percentage peak current time holding in pulse period. It should be ad-
justed according to users' technical requirements.
