Abstract
A hot wire type electric arc welding torch includes a wire heating unit which has a first guide hole therein disposed substantially parallel to a welding torch. An insulative guide is connected to the wire feeding unit and supplies a wire to the welding torch at an angle which is inclined relative to the first guide hole. An insulative spacer is disposed in the wire feeding unit, and the insulative spacer has a guide hole therein which forms an angle with the first guide hole for bending the wire. Tapered escape hole portions are formed at wire inlet and outlet sides of the insulative spacer to minimize friction.
