Abstract: A movement support includes a base. An air inlet is formed in the base. A drainage plate is installed on the base. A first heat dissipating flow channel communicated with the air inlet is formed in the base on one side of the drainage plate. A second heat dissipating flow channel communicated with the air inlet is formed in the base on the other side of the drainage plate. The first heat dissipating flow channel and the second heat dissipating flow channel between the drainage plate and the air inlet are communicated with each other.

Abstract: The invention provides a double-power-supply switching control system for a welding machine and method. The welding machine double-power-supply switching control method comprises the steps of: continuously detecting and modifying an input voltage signal by a signal modification unit; under the control of a control unit, judging, by a judgment unit, whether to perform voltage doubling, controlling to execute voltage doubling switching action, and locking an actual input voltage mode of a welding machine by a locking unit; and finally outputting matched output current by a power supply output unit.
