Embodiment 1

[0020] Such as figure 1 As shown, this embodiment includes a transformer, a controller, a circulating cooling water tank, a water-cooled cable, and welding tongs. The transformer is connected to the circulating cooling water tank and the controller. The water-cooling cable passes through the circulating cooling water tank. The welding tongs are connected to the transformer through the water-cooling cable. It also includes a water flow flood preventer arranged in the circulating cooling water tank, the water flow flood preventer is connected with the controller, and a heat dissipation fan is provided on the top of the transformer. The equipment is powered on, and the water inlet switch on the circulating cooling water tank is turned on. When the cooling circulating water passes through the water flow generator, the controller is turned on to let the equipment enter the working state; when the cooling water switch is closed, no cooling water flows through the water flow. The floo...

Embodiment 2

[0024] Such as figure 1 As shown, in this embodiment on the basis of embodiment 1, the water flow flood preventer includes a temperature sensor, a water level sensor, an alarm, and a control circuit, and the control circuit is connected to the temperature sensor, the water level sensor, and the alarm respectively, The control loop is connected to the controller. The control circuit is the command center of the water flow flood preventer. When the water level sensor detects that the water level in the circulating cooling water tank is low, it will transmit a signal to the control circuit, and the control circuit will control the alarm to give a buzzer prompt; if it is in the circulating cooling water tank When the temperature rises sharply due to lack of water, the temperature sensor transmits the signal to the controller through the control circuit, and the controller directly cuts off the power supply to avoid the water-cooled cable from burning out due to excessive temperatur...

Embodiment 3

[0026] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment further includes an electric shock prevention device provided on the input end of the transformer. When an electric welding machine that can automatically start and stop is empty, the voltage of the DC welding machine is 55-90V, and the AC welding machine is 60-80V, both of which exceed the safe voltage value, but because the voltage is not very high, it is often ignored. In particular, the electrical hazard of welders is relatively high. According to calculations, when the welder’s no-load voltage is 70V, people are operating in a humid place, and the protective equipment is not properly worn, the human body resistance RR at this time is about 1600Ω, if the welder’s hand touches the jaws, the current through the human body IR = V / RR=70 / 1600=0.044A=44MA. Under the action of this current, the welder’s hands will spasm, causing ventricular fibrillation. If the rescue is not timely, there will be a ri...

Abstract

The invention relates to an electric welding machine capable of being automatically started and stopped. The electric welding machine capable of being automatically started and stopped comprises a transformer, a controller, a circulating cooling water tank, a water-cooled cable and an electrode holder; the transformer is connected with the circulating cooling water tank and the controller; the water-cooled cable penetrates the circulating cooling water tank; the electrode holder is connected with the transformer through the water-cooled cable; a water flow flood prevention device is arranged in the circulating cooling water tank and connected with the controller; a cooling fan is further arranged on the top of the transformer; and an automatic starting and stopping circuit is further included. When the welding machine works, the transformer generates large heat as well, the arranged cooling fan can take away the heat generated by the transformer, and it is guaranteed that work of the transformer is stably performed; due to the arrangement of the automatic starting and stopping circuit, the idle running time of the welding machine can be shortened, consumption of electric energy is reduced, and when the welding machine bears no load, the automatic starting and stopping circuit can control the welding machine to be automatically powered off; and during welding, a welding electrode makes contact with a weldment, a switch in the automatic starting and stopping circuit is automatically turned on so that current can be supplied to the welding machine, and the energy conservation purpose is achieved.

Description

Technical field [0001] The invention relates to the field of electric welding, in particular to an electric welding machine that can automatically start and stop. Background technique [0002] In the production process of automobile and other covering parts products, welding machines and welding robots have become key equipment to improve production efficiency and ensure product quality. According to the working characteristics of the equipment, corresponding protective measures can be taken to ensure the safety and energy saving of the equipment. effect. Welding machines have greatly improved the productivity of enterprises, and the competitiveness of their products has also been greatly improved. However, many shortcomings were found in the course of use. The reason is that the water cable of this equipment has too short service life, damaged too fast, and the replacement frequency is too high. This not only causes the equipment to be frequently shut down for maintenance, whi...
