Abstract
A non-transferred plasma arc system, which is provided with a non-transferred plasma torch () that is provided with a non-consumable electrode () as a negative electrode and an insert chip as a positive electrode, the insert chip being cooled by a circulated coolant (W) and the insert chip releasing a plasma arc onto a workpiece. The plasma arc torch () comprises a TIG welding torch () that is provided with the non-consumable electrode (), whereby an arc is generated between the workpiece and said electrode (), and a torch nozzle (), which releases a shield gas toward an arc-generated weld pool of the workpiece. The plasma arc torch () is provided with an attachment () that is detachably attached to the TIG welding torch () while surrounding the periphery of the torch nozzle () and that functions as the insert chip, whereby a non-transferred plasma arc is inexpensively and easily used.
