5 Welding mode optional as DC MMA | DC TIG | AC TIG| Pulse TIG | AC Pulse TIG
DC TIG – DC positive connection (workpiece connected to positive , welding torch to negative) is used, which has the advantages of stable and concentrated arc, less damage to the tungsten electrode, relatively large welding current, and narrow and deep welds.
AC TIG – Adjust the cleaning Knob to clean the oxide film, maximum penetration and minimum rungsten loss.
Pluse TIG -The base current is used to maintain the ionization channel of the main arc, anda pulsed arc is generated by periodically adding a high peak pulse current of the same polarity to melt the metal and control the droplet transfer.
AC Pulse TIG -Pulse and AC mode are mixed to obtain a more perfect welding process.
