<p>The present invention relates to a hose for a polyvinyl chloride (PVC) welding machine, comprising a branch member which has a horizontal path whose both ends are horizontally penetrated in the branch member and a vertical path which is vertically penetrated in the horizontal path; a connection hose which connects one end part of the horizontal path to a welding gun; an air hose which connects the vertical path to an air generating device and supplies air supplied from the air generating device to the welding gun with use of the connection hose; a wiring hose which is connected to the other side of the horizontal path in the branch member; and a power line connected to a power plug which passes the wiring hose and the horizontal path of the branch member to be connected to the welding gun. In the present invention, the welding gun is connected to one connection hose, thereby preventing interruption or twist with another hose in a process of moving the welding gun and enabling the welding gun to move in a stable manner, leading to improvement of the accuracy and usability of the welding.</p> |
