とを特徴とするプラズマ切断トーチ。 In a plasma cutting torch, an electrode is attached to the tip of a core tube provided inside the torch body, a support tube is fitted onto the core tube through an insulator, and a tip and a shield cup are attached to the support tube. A gas inflow path is formed that penetrates the electrode and reaches near the tip of the electrode, communicates with the gas inflow path near the tip of the electrode, passes through the electrode and the core tube adjacent to the gas inflow path, and then passes through the core tube. A cooling passage is formed through an orifice drilled in the insulator and the support cylinder, and the cooling passage is branched into two, with one branch being used for plasma working gas flow between the chip and the electrodes. A plasma cutting torch characterized in that the tip and the shield cup are connected to each other, and the other branch path is connected between the tip and the shield cup.
