NON-TRANSFERRED PLASMA ARC SYSTEM, CONVERSION ADAPTER KIT, AND NON-TRANSFERRED PLASMA ARC TORCH

摘要

A non-transferred plasma arc system, which is provided with a non-transferred plasma torch (1) that is provided with a non-consumable electrode (101) 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 (1) comprises a TIG welding torch (100) that is provided with the non-consumable electrode (101), whereby an arc is generated between the workpiece and said electrode (101), and a torch nozzle (105), which releases a shield gas toward an arc-generated weld pool of the workpiece. The plasma arc torch (1) is provided with an attachment (51) that is detachably attached to the TIG welding torch (100) while surrounding the periphery of the torch nozzle (105) and that functions as the insert chip, whereby a non-transferred plasma arc is inexpensively and easily used.

主权项

1. A non-transferred plasma arc system comprising a non-transferred plasma arc torch and a power unit for supplying power and gas to the non-transferred plasma arc,
wherein the plasma arc torch comprises a non-consumable electrode and an insert chip, wherein the insert chip is provided as an anode for emitting a plasma arc to the workpiece while the insert chip is cooled by circulation of coolant, and the plasma arc torch comprises a portion which repurposes a TIG welding torch comprising the non-consumable electrode which generates an arc between a workpiece and the non-consumable electrode, and a torch nozzle which releases a shielding gas toward the molten pool of the workpiece caused by the arc, and an attachment which functions as the insert chip and is provided so as to be freely attachable and detachable to and from the TIG welding torch in a state that the attachment surrounds the periphery of the torch nozzle.
