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.
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-
Ÿ
justed according to users' technical requirements.
