三功能一体式IGBT逆变焊机

A Three Function in One IGBT Inverter Welder

弧焊逆变电源由于使用了ＰＷＭ芯片等集成电路以及先进的电子控制技术，目前弧焊逆变电源不仅用于ＭＭＡ，在其它熔焊方法：如ＴＩＧ、ＭＩＧ、ＭＡＧ以及ＡＰＣ等领域均得到应用。本文将在ＭＭＡ电源的基础上，着重介绍一下：集手工焊、ＴＩＧ直流脉冲及ＴＩＧ交流脉冲方波于一体的三功能逆变焊机的一些特点。

Since the use of PWM and advanced electronic control technology,the arc inverter weldingpower source is not only used in MMA,but also found use in TIG、MIG、MAF and APC、Based on MMApower source,We take emphasis to introduce some characters about a″Three in One″ inverter welderwhich has three functions:metal arc welding、TIG DC pulse welding and TIG AC pulse square wavewelding.
