What is the output voltage and current of electric welding machine using covered electrode?

The output voltage and current of electric welding machine using covered electrode are as follows:

Regular welding machines have current regulators ranging from 50 to 600A, and the output voltage is divided into no-load voltage and working voltage. No-load voltage refers to the voltage when the welding machine is not working, which is about 50 V-70 V When the voltage is high, it is easy to ignite the arc. The working voltage refers to the voltage during normal welding after igniting the arc, which is about 30 V, and the current is related to the workpiece to be welded. When the thickness of the workpiece is large, the required current is also large, and vice versa.
