The present invention relates to a torch device capable of adjusting current and voltage of a carbon dioxide arc welding machine which is well used in a welding industrial site. The welding machine necessary for welding work which is capable of manufacturing a welding structure is a welding source, a welding cable, a wire feeding device, a welding torch, etc. A current and voltage adjusting volume is directly installed in a torch of a carbon dioxide welding machine, so an electric wire is connected along a control cable, and a torch cable protects thereof. A volume is installed to adjust the output voltage of a welding machine and the wire speed in welding or before and after welding. Therefore, a welding defect generated in welding can be prevented, and the high quality welding product can be manufactured thereby. A welding torch clip (9) can be mounted on a current volume (6) and a voltage volume (7), and the current volume (6) for determining the speed of a welding wire by receiving the current outputted through a control terminal is mounted on a welding torch. The voltage volume (7) adjusts the voltage, so the output voltage of the welding machine can be adjusted. A control cable (13) is built in and connected to the inside of the torch cable (10). A feeding motor is operated and carbon dioxide is supplied by the operation of a micro switch (8). The current is supplied to the wire of the welding torch, and an arc is generated according to the welding source set thereby. Therefore, continuous welding, which a user desires, can be performed. |
