A forced pressure power supply torch comprising:- a first conductive tip body that is connected to a torch body and has a first wire insertion hole formed in a portion of the first tip body in an axial direction; a pressurization shaft that is passed through the first wire insertion hole of the first tip body and has a second wire insertion hole; a compression spring having a first end engaged with the torch body and a second end held in contact with the pressurization shaft; a second conductive tip body that is detachably connected to a distal end of the first tip body and has an accommodation hole formed in a central portion of the second tip body in the axial direction; a power supply tip having a third wire insertion hole formed in a central portion of the power supply tip in the axial direction, the power supply tip being removable from the accommodation hole after the second tip body is removed from the first tip body, wherein, when the second tip body is connected to the first tip body, the power supply tip is arranged along the axial direction in the accommodation hole and urged by the compression spring with a proximal end of the power supply tip held in contact with the pressurization shaft; and a conductive tip cover that is detachably connected to a distal end of the second tip body and arranged in such a manner as to cover a distal end of the power supply tip, the tip cover having a fourth wire insertion hole; wherein a tapered surface (61 a) is formed in the fourth wire insertion hole of the tip cover; wherein a tapered contact surface that contacts the tapered surface of the tip cover is formed in the power supply tip; wherein the compression spring urges the contact surface of the power supply tip to contact the tapered surface (61 a) of the tip cover; and wherein the tip cover is arranged in such a manner as to form a clearance between an inner surface of the fourth wire insertion hole and the power supply tip: and characterized in that the power supply tip has a projection, formed on an outer circumferential surface of the power supply tip and engaged with an engagement step (51 e) formed in the accommodation hole of the second tip body, that prevents the power supply tip from moving along the axial direction in the accommodation hole of the second tip body and coming off the accommodation hole at the distal end of the power supply tip. a first conductive tip body that is connected to a torch body and has a first wire insertion hole formed in a portion of the first tip body in an axial direction; a pressurization shaft that is passed through the first wire insertion hole of the first tip body and has a second wire insertion hole; a compression spring having a first end engaged with the torch body and a second end held in contact with the pressurization shaft; a second conductive tip body that is detachably connected to a distal end of the first tip body and has an accommodation hole formed in a central portion of the second tip body in the axial direction; a power supply tip having a third wire insertion hole formed in a central portion of the power supply tip in the axial direction, the power supply tip being removable from the accommodation hole after the second tip body is removed from the first tip body, wherein, when the second tip body is connected to the first tip body, the power supply tip is arranged along the axial direction in the accommodation hole and urged by the compression spring with a proximal end of the power supply tip held in contact with the pressurization shaft; and a conductive tip cover that is detachably connected to a distal end of the second tip body and arranged in such a manner as to cover a distal end of the power supply tip, the tip cover having a fourth wire insertion hole; wherein a tapered surface (61 a) is formed in the fourth wire insertion hole of the tip cover; wherein a tapered contact surface that contacts the tapered surface of the tip cover is formed in the power supply tip; wherein the compression spring urges the contact surface of the power supply tip to contact the tapered surface (61 a) of the tip cover; and wherein the tip cover is arranged in such a manner as to form a clearance between an inner surface of the fourth wire insertion hole and the power supply tip: and characterized in that the power supply tip has a projection, formed on an outer circumferential surface of the power supply tip and engaged with an engagement step (51 e) formed in the accommodation hole of the second tip body, that prevents the power supply tip from moving along the axial direction in the accommodation hole of the second tip body and coming off the accommodation hole at the distal end of the power supply tip.
