ZX7 Series IGBT Inverter ARC Welding Machine/Welder

逆变式弧焊设备的出现得益于

逆变电源理论和器件的出现。逆变弧焊电源是先将 50/60Hz 的工频交流整流为直

流，然后利用大功率功率器件 MOSFET 场效应管将直流转换为高频（如

100KHz 或更高）。再降压整流，通过脉宽调制技术（PWM）输出大功率直流源，

由于采用了开关电源逆变技术焊机主变压器、电抗器的重量、体积大幅度下降，

效率提高 30%。逆变焊机的问世被专家誉为焊机产业的一次革命。

Inverter arc welding equipment generation was benefit from the inverter theory

and devices appearance. Inverter welding power source produce that is to make

50/60Hz frequency AC rectify into DC, and then use high-power power device

MOSFET FET DC converter into high frequency (100KHz or higher)， and

depressurization rectification, by pulse width modulation (PWM) to output

high-power DC, and due to adopt the main transformer of a switching power supply

inverter technology welding machine, the weight of the reactor, and the volume

dropped significantly, but the efficiency increase to 30%. The advent of inverter

welder was by experts as a welder industrial revolution.

逆变式手弧焊机可提供更强、更集中、更为平稳的电弧，在进行短路熔滴

过渡时，焊条与工件发生短路后，其反应更加迅速。此外，此类电源可装配电弧

调节装置，这意味着可设计成不同的动态特性的焊机，对动态特性进行调节，使

电弧更软或更硬。

Inverter arc welding machine with more power, more focused, more stable

electric arc, in the progress of short circuit molten drop transition, electrodes and the

workpiece after a short circuit, which reacted more quickly. In addition, this type of

power supply to install arc distribution adjusting device, which means you can design

different dynamic characteristics of the welding machine, to adjust the dynamic

characteristics, make ARC softer or harder. .

逆变式手弧焊机系列的特点是：高效、节能、轻便、且具有良好的动特性，

电弧稳定，溶池容易控制。较高的空载电压和较好的能量推力补偿，用途广泛。

可焊接不锈钢、合金钢、碳钢、铜和其他有色金属。该焊机可使用各种不同规格

和材质的焊条，包括酸性、碱性及纤维素型的焊条。可用于高空作业，野外作业，

室内外装修等，与国内外同类产品相比具有体积小，重量轻、安装简便，操作容

易等特点。适用于

The characteristic of Inverter arc welding machine series is high efficiency,

energy-saving, light, and has a good dynamic performance, stable electric ARC,

dissolved pools easy to control, with high no load voltage, better energy thrust

compensation, and a wide range of uses. This Inverter arc welding machine can weld

stainless steel, alloy steel, carbon steel, copper and other nonferrous metals and was

suitable for a variety of different sizes and materials of electrodes, including acidic,
