How many volts are there in welding line when argon arc welding machine is welding?

Answer:

How many volts are there in welding line when argon arc welding machine is welding?This question is a little professional, but asked so professional, so how can I not for a bit and you answer:From the actual welding voltage, welding, or welding arc voltage arc column, and the pressure drop causes some conductive impedance on the other; but this voltage is the voltage of the arc column in the dominant component, so we usually ignore other voltage;Then the arc column voltage is mainly composed of three parts: the arc column and tungsten needle end face excessive voltage, the middle arc column voltage, the arc column and the workpiece surface excessive voltage;The actual value only third points: design experience, argon welding output voltage Uo = 14V+ (0.04 * Io input current);

It's probably around 20~40V!

No load voltage: when the welding machine is energized, but no welding operation (no arc), the voltage on the output terminal of the welder is usually between 60~80V;Load voltage: of course, the output voltage of the welder when there is arc (with current or pressure drop), or the voltage between the weldment and the weldment is usually half or less than that of the no-load (with respect to the current);Working voltage: more general, can refer to the power supply voltage, load, output voltage and welding arc voltage of welding machine.
