摘要:
A method and apparatus for generating a plasma arc used in arc welding, arc transformation hardening, minute working, etc. A plasma gas used for generating a plasma arc includes xenon. A tungsten electrode having a diameter of 0.5 millimeters or less is used. Thus, an extremely low plasma arc current of 0.1 amperes or less can be produced in a stabilized manner.
