| Post subject: | Arc Voltage accross 1mm Gap |
Bonjour, I'm working on a DC arc generator. This generator is able to create an arc beetween two electrodes of tungsten. The DC Voltage is about 300V and the arc is stable. I measure the arc voltage of about 200V for a gap of 1mm. I have found figures with the arc voltage and current for different gaps here : http://www.arcadvisor.com/faq/dc_direct_current_arc.html. This figures tells that the voltage must be of about 50V for 10 mm gap, and this is in condradiction with my measure. My question : is my measure false (have i ommitted something) or are the figures false ? Thanks |

Please provide the generator load curve. - Michael www.arcadvisor.com |

The generator is a simple transformer whith a rectifier device to generate DC voltage. I haven't got yet the generator load but what i'm sure is that it's neglgible to the resistive serial load I added for arc current control. How can this generator load change the Arc voltage ? |
