Energy saving security controller for electric welding machine

Abstract

The invention discloses an energy saving security controller for an electric welding machine. The energy saving security controller for the electric welding machine structurally comprises a waterproofliquid crystal display screen, a hand lifting rod, a control panel, an electric welding host, ground feet, cooling holes, an electric welding machine plug hole, a speed adjusting rotator, a power switch and a prompting lamp; the waterproof liquid crystal display screen is electrically connected with the control panel through a single-chip microcomputer; the prompting lamp is electrically connected with the single-chip microcomputer in the control panel; the cooling holes and the electric welding host are of an integrated structure; the bottom of the electric welding host is welded to the topsof the ground feet; the electric welding machine plug hole is embedded in the electric welding host; and the speed adjusting rotor is electrically connected with the power switch through the controlpanel. According to the energy saving security controller for the electric welding machine, the structure is provided with the waterproof liquid crystal display screen which is connected with the electric welding host, the waterproof liquid crystal display screen can prevent the outside water from entering the display screen, and a sealing and protecting role is played on parts in the liquid crystal display screen, so that it can be avoided that parts in the liquid crystal display screen are damaged.

Description

technical field [0001] The invention is an energy-saving safety controller for an electric welding machine, which belongs to the technical field of electric welding machines. Background technique [0002] In the machine repair workshop of the mining factory, there are a lot of welding processing tasks every month. Many electric welding machines are running at full capacity almost every day. When the electric welding machines are in use, due to factors such as adjustments to weldments, slag removal, or other temporary work , so that the welding machine is often in a no-load standby state. A large amount of electric energy is wasted during no-load operation, which increases production costs. In addition, when the welding machine is unloaded, the output voltage of the secondary side is about 60-70V, which is not a safe voltage. If you accidentally touch the bare metal during operation, it is easy to cause an electric shock accident, and there are potential safety hazards. Pro...
