产品概述

该系列焊机是一夽先进的焊接设备。应用广泛,焊接变压器体积小而输出能量大,三相交流电经整流后转换成为直流,再经由IGBT组成的逆变电路逆变成为中频1000HZ方波接入焊接变压器的初级,经焊接变压器降压整流成为脉动很小的直流电供给电极对工件进行焊接。逆变器通过反馈回来初级或者次级焊接电流进行调整IGBT的占空比,从而达到焊接过程恒流的效果。

Description

Medium frequency inverter spot welding machine is an advanced welding machine wide application.The welding transformer is in small size but the output energy is large.Three-phaseACwill be converted intoDCafter being rectfied。Then theDC will be converted into medium frequency1000Hz square wave to be connected to primary welding transformer through the inverter circuit which is composed of LGBT.The MF square wave will become small pulseDCto the electrode for welding work Piece through the depressurization and rectifying process in the welding transformer.The inverter will adjust the duty ratio of IGBT through the feedback primary or secondary current so as to achieve current of the welding process.

性能特点

Features

1.    The current in secondary welding loop is DC.Dramatically reduce the impact to the welding current due to the inductive reactance in secondary loop when conducting welding to the work piece.

2.    Three-phase balanced load can reduce the requirement to the power supply system.The power factr is close to1.No electrical inductance,so no need to adjust the power factor.

3.    Eradicate the contamination to the power supply. Lt is a kind of environmentally friendly welding method.No need to provide power independently.lt is able to be used together with robotic welding ssystem.

4.    Reduce power consumption,energy saving.Reduce the requirement of cables and lots of maintenance cost.

5.    The weight of transformer is reduced greatly .lt is light and convenient.The weight and size of the MF transformer is only1/3 of theAC type transformer. Suitable for robot welding system.

6.  lncrease the heat input efficiency.The output of welding transformer isDC voltage,without the disturbance of inductance.Pure DC has no defect of zero passage.The efficiency of heat is enhanced dramatically.

7.  Lntelligent digital full-closed loop control.The welding control current will be more precise.The adjustment precision and monitoring precision is20 times higher than theAC system.Be able to protect the inverter and transformer.

8.  Lncrease the stability of the welding technology.DCwelding technology is good and the welding parameters are of wide application.The secondary current could achieve actual constant current.Have better using prospect thanAC.
