  • Multi-process: DC TIG/Pulse TIG
  • 100% arc starting success rate: high-frequency arc starting cooperates  with suitable arc striking current, outstanding arc striking performance
  • Short circuit protection: prevent tungsten electrode from sticking with the  workpiece due to short circuit during welding
  • Multiple wire feeding modes: pulse simultaneous/constant speed wire  feeding modes, realizing excellent welds formation
  • Stable wire feeding: 4-roll drive system + encoder speed feedback,  realizing high-precision smooth wire feeding
  • Abundant robotic communication interfaces: It can achieve CAN/485/DEVICENET/ ETHERNETIP/ETHERCAT/PROFINET and other digital  communication through digital interface box, and human-machine control  through analog and switching value
