PURPOSE: A hot air welding device for synthetic resin, capable of controlling the height and the angle of a workbench is provided to control the angle in the front and rear directions according to the selection of an operator and to improve the working efficiency by ensuring an optimal working condition for the operator. CONSTITUTION: A hot air welding device for synthetic resin, capable of controlling the height and the angle of a workbench comprises a workbench (300), a control box (400), and a support arm (500). A support member (200) includes a fixing pipe, a lifting pipe, a first actuator, a rotary shaft, and a second actuator. The first actuator is connected to a support plate (100) and the lower surface of the support plate inside the fixing pipe and controls the lifting of the lifting pipe. The second actuator connects an extending plate and the rear lower surface of the workbench and controls the back-and-forth motion of the workbench.
