Hi Joshua
The connection point looks like that you have had reconnected it by yourself, did you have replace a laser tube for the laser before?
Please download a document that on how to replace a laser tube from below link, it has several pages to teaching you on how to reconnect the connection for two wires, it's very important.

If you did not rewired and resoldered the wire to good, there will be keeping a spark at the connection.
Not bad wire, it's also not too much power.
