Title: WELDING MACHINE
Abstract:
A welding machine comprises a main machine (4), a motor, a transmission mechanism (8), and a U-shaped rotating piece (7). The motor drives, via the transmission mechanism (8), the U-shaped rotating piece to rotate in a clockwise or counterclockwise direction. The main machine (4) has a U-shaped opening. A U-shaped cable guiding piece (9) is disposed at the U-shaped rotating piece (7). A welding gun frame (11) is disposed at the U-shaped cable guiding piece (9). A welding gun head (10) is disposed at the welding gun frame (11), and connected to a cable (2). A bridge plate (16) is hinged to one side of the U-shaped cable guiding piece (9). The bridge plate (16) can rotate to close an opening of the U-shaped cable guiding piece. The welding machine is not limited by the length and shape of a small tube base, implementing automated welding, moving flexibly, being simple in operation, and increasing welding quality and efficiency.
