[3dem] Thank you for your support! - Arcing in the gun chamber

[kunihiro uryu]

Dear Colleagues,

Many thanks to your kind reply to my inquire. Support from you and our
engineer from the vendor gave me better understanding and a significant
improvement. Clearing of the gun chamber made a big improvement. We haven't
heard a arch for a few weeks now. Thanks again!

Regards,
Hiro
