It brings customers higher quality and higher efficiency welding experience and value with excellent arc characteristics, reliability and high efficiency, and helps customers ...

(1) Spot welding: The weldment is pressed between the two cylindrical electrodes, heated by electricity, so that the weldment melts at the contact to form a nugget, and then the power is cut off, and it solidifies and crystallizes under pressure to form a dense solder joint. Spot welding is suitable for welding thin plates (laps) and steel bars below 4 mm.

The first is that the PLC sends a start/stop signal to the server through the I/O point, and the server controls the operation of the servo motor. The PLC controls the operation/stop of the servo through the digital output, so as to achieve the purpose of controlling the servo motor. The second is through the pulse output of the PLC, which ...

1. PLC industrial gateway has rich interfaces and is easy to deploy It supports 4G, 3G, PPPOE, Wi-Fi network, digital IO input and output, and serial terminal communication, providing different access solutions for different applications. 2. Intelligent analysis and efficient access Inline protocol analysis ...

Laser spot welding machine, also known as resistance welding machine, is usually divided into three categories according to the nature of the welding power source: 1. AC spot welding machine; 2. Energy storage spot welding machine; 3. DC spot welding machine. 1. AC spot welding machine Precision AC spot welding machine generally refers to the spot welding machine with a power of less than 16KVA.

Peripheral circuit component failure This type of failure often occurs in the failure of the PLC after a certain period of work. In the PLC control loop, if there is a component damage fault, the PLC control system will immediately and automatically stop working. The input circuit is PLC to accept switching quantities, analog quantities, etc.

1. Power components The power supply assembly is used to provide the power required for the operation of the PLC, and the external power supply can be converted into a power supply for the PLC internal and applicable to the case. 2. Microprocessor CPU and memory components Microprocessor CPU is the core device of PLC, and CPU is different from each manufacturer.

1. The ladder diagram language is the most commonly used programming language in PLC programming. The CPU reads physical input into a memory table, often referred to as an "input table". The form is evaluated for use in the procedure. Different platforms, using different types of registers; In each scan cycle, follow from left to right, ...

What aspects should be paid attention to in the application and protection of AC arc welding machine: (1) It should be used according to the additional welding current and load continuation rate of the welding machine, and should not be overloaded. (2) The welding machine is not allowed to be short-circuited for a long time. (3) The regulating current should be operated at no load. （4） ...

1. When the oscilloscope looks at the current monitoring output of the driver, it finds that it is all noisy and cannot be read Cause: The current monitoring output is not blocked from the AC power supply (transformer). Solution: You can use a DC voltmeter to detect and investigate. 2. Servo motor high speed ...

Sinusoidal Pulse Width Modulation (SPWM) control mode It is characterized by simple structure of control circuit, low cost, good hardness of mechanical characteristics, and can meet the smooth speed regulation requirements of general transmission, and has been widely used in various fields of industry. However, this type of control is at low frequencies, ...

From April 13 to 16, 2021, CHINAPLAS 2021 was grandly held at the Shenzhen World Convention and Exhibition Center (Bao'an New Hall) with the theme of "New Era· New Power, · Sustainable Innovation". As a vane of rubber and plastics professions and a barometer of shopping malls, the World Rubber and Plastics Exhibition has a 350,000 square meter ...

1. In this computer, right-click, manage, check to find the device manager, plug in the USB-PPI cable (one end is connected to the computer, the other end is connected to the PLC), the computer device manager will pop up the port USB-SERLAL CH304 (com3), the number in parentheses may change, indicating that you have found the cable. This...

1. Use the analog output module of the PLC to control the inverterThe analog output module of the PLC outputs a 0-5V voltage signal or a 4-20mA current signal, which is used as the analog input signal of the inverter to control the output frequency of the inverter. This control method is simple to wiring, but requires the option to ...

(1) The ambient temperature exceeds the range of 0-50 °C; (2) The relative humidity exceeds 85% or there is dew condensation (caused by sudden temperature changes or other factors); (3) direct sunlight; (4) There are corrosive and flammable gases, such as hydrogen chloride, ...

(1) Use the analog output module of PLC to control the analog output module of the inverter The analog output module of the PLC outputs 0-5V voltage signal or 4-20mA current signal, which is used as the analog input signal of the inverter to control the output frequency of the inverter. This control method is simple to wiring, but it needs to be selected and changed.

The inverter is composed of a main circuit, a rectifier, a flat wave circuit, and an inverter. 1) Main circuit: The main circuit is the power conversion part that provides voltage regulation and frequency regulation power supply for the asynchronous motor, and the main circuit of the inverter can be roughly divided into two categories: the voltage type is the DC ...
