    • A system and method for forming an arc between an electrode and a workpiece is disclosed. The present invention includes a method of initiating an arc that includes comparing voltage across output terminals of a stick welder to a voltage threshold, and if the voltage across the output terminals is less than the voltage threshold, increasing the voltage across the output terminals to an arc formation OCV. The output voltage of the stick welder will be driven to a lower OCV if an arc is not formed between an electrode and a workpiece within a given period of time.
    • 公开了一种用于在电极和工件之间形成电弧的系统和方法。 本发明包括一种启动电弧的方法,该方法包括将焊接机的输出端子上的电压与电压阈值进行比较,并且如果输出端子两端的电压小于电压阈值,则将输出端子两端的电压增加到 电弧形成OCV。 如果在给定的时间内没有在电极和工件之间形成电弧,焊接机的输出电压将被驱动到较低的OCV。
