Equipment principle:

Inverter DC resistance spot welding power supply is a new type of power supply developed by IGBT inverter technology, two pieces of 32-bit microcomputer control technology and modern power electronic technology. Due to the use of ac-dc-ac-dc conversion technology, the time control accuracy reaches 0.1 millisecond level, the control response and control accuracy are greatly improved; the DC output improves the welding process significantly; the application of 32-bit microcontroller (MCU) and electronic technology makes the equipment have more functions, including medium and high frequency sampling, digital control, monitoring, fault diagnosis and protection, data transmission, etc. This kind of equipment is especially suitable for spot welding of copper, aluminum and other non-ferrous materials, alloy materials, precision parts and high-quality products.

Specification and model of inverter spot welding machine:

Features of inverter spot welding machine:

1. The welding current is pulsating DC (with small ripple); the inverter frequency is 1-8khz, the power on time control cycle is 0.1ms, and the discharge time can be adjusted and controlled arbitrarily;

2. It can monitor current, voltage and power in real time;

3. It has the function of fault diagnosis and alarm such as current abnormality, monitoring value overrun, network voltage overrun, overheat, etc., which can greatly reduce the defective rate of product welding.

4. Three stage heating setting, with the function of slow rise and slow drop of current, can effectively solve the "spatter" and ensure the stability of welding.

5. The electrode life can be effectively prolonged. Energy saving is more than 50%.

Inverter spot welding machine is especially suitable for the following industries or high requirements of materials welding:

Automotive parts | automotive electronics | automotive electrical appliances | electric light source ﹤ various types of inductance enameled wire ﹤ battery nickel plate, combined battery | precision enameled wire welding
