An inside portion of the TIG torch supporting arm is formed of an electroconductive material. The apparatus further includes water-cooling welding cable hoses which are attached to a water tank, extend through the inner side of the torch handle, and are attached to the TIG torch. The water-cooling welding cable hoses being formed with electroconductive cables provided therein. The apparatus may additionally include a TIG torch rotation block which is rotatably mounted to the wire-feeding curved nozzle and fixed to the TIG torch supporting arm. Thus, a semi-automatic TIG welding apparatus is provided wherein a TIG welder can freely adjust the position of the welding wire, and wherein the welding wire can be inserted to an ideal position, and also wherein the wire-feeding curved nozzle and thus the wire do not fluctuate in position, resulting in great savings in the expense and time related to TIG welding, and also in the amount of labor on the part of the welder.
