If you want to go high-speed welding with TIG welding you need to use high current. When you use high current; fusion and arc force will be very high and will be broken to the base material. So impossible to go highspeed welding with single tungsten and a single power source. Until now everyone knows TIG welding is good quality but slow welding. Dual tungsten technology makes a wide area and gets softer arc force and gives more area for filling material. Also base material fusion depth become less than Iron mixing in the fusion area very less. So getting more quailty.
