Abstract

PURPOSE:To interrupt arc current flowing to a work via a tip from an electrode so that the safety of operation is assured by subjecting the outside circumference of the tip which ejects a plasma working gas from the tip hole to an insulating treatment. CONSTITUTION:An insulation coating is provided on the outside circumference 16C of the tip 6 which ejects the plasma working gas Ga. The insulation coating 16C is constituted of a film consisting of 'Teflon(R)', epoxy resin, ceramics, etc. The material and the thickness of the film, etc., are adequately selected so that the insulation breakdown strength attains >=2kV. The safety of the operation is assured by such constitution.
