目前使用的脉冲焊机多为并联式,由两部分组成,即维弧电源和脉冲电源相并联。这种电源有一个缺点:在调整规范时,两部分的输出互有干扰,调节参数多,规范调节较困难,使用也不方便。而一体式脉冲焊机则克服了上述缺点,它的调节与一般焊机一样,因此,使用比较方便。 Pulse welder currently used mostly parallel, consists of two parts, namely the arc power and pulse power in parallel. This power supply has a drawback: when adjusting the specification, the outputs of the two parts interfere with each other, the adjustment parameters are many, the regulation of the specification is difficult, and the use is inconvenient. The integrated pulse welding machine overcomes the above shortcomings, its regulation and general welding machine, therefore, more convenient to use.
