I am new here and have just had a catastrophic failure on a relatively new laser cutter from China. We impoerted the 160 max watt machine from AlphaCNC and it worked fine unitl it just stopped cutting after sitting for about 1 month. It began to do some wierd arcing in the anode end of the tube, loud crackling sounds and now all I get is this (please see video link) Any ideas why the arc would go backwards and not to the ring, and along the glass tube?

Regards Richard
