<p>The present invention relates to a gas welding torch with a maximized radiation area, and specifically, to a gas welding torch with a maximized radiation area, comprising a diffuser, an insulator, a tip and a nozzle main body, wherein a various number of cooling holes are formed in the center or inside of the diffuser on the circumferential surface of the diffuser in order to maximize the radiation area of the diffuser, and a various number of gas-moving long grooves are formed inside the insulator in order to facilitate the movement of carbon dioxide, thereby effectively preventing the deformation and shortened lifetime of the diffuser due to an excessive temperature increase and allowing welding to be continuously carried out for a long time. Therefore, welding becomes convenient and welding velocity is remarkably improved.</p> |
