At rear of the body frame, a hub(13) whereon the welding wire is wound is installed. A feeding adapter(20) guiding withdrawal of the welding wire is installed in the center of the body frame. A press roller assembly(26) with a pressurizing roller is installed on the axial line of the feeding adapter. In the upper end of the press roller assembly, a pressurizing handle(27) adjusting pressurizing force applied on the welding wire is installed. In a portion of a roller(28), a printer motor(19) is placed. In the upper of the body frame, a control box(16) controlling the printer motor is installed.
