PURPOSE: A combining structure of a plasma torch and a guide cap is provided to easily separate a separable cap unit from a fixing cap unit as the density of first threads is lower than the density of second threads. CONSTITUTION: A combining structure of a plasma torch and a guide cap comprises a plasma torch, a first O-ring(120), and a guide cap(200). The first O-ring is coupled to the outer surface of the plasma torch. The guide cap comprises a fixing cap unit(210), a second O-ring(220), and a separable cap unit(230). The fixing cap unit encloses the first O-ring, and one end of the fixing cap unit is connected to the outer surface of the plasma torch by a screw. The second O-ring is coupled to the outer surface of the other end of the fixing cap unit. One end of the separable cap unit encloses the second O-ring, and is connected to the other end of the fixing cap unit. A through hole which discharges plasma is formed on the other end of the separable cap unit. The separable cap unit is detachably connected to the fixing cap unit.
