What is the right way to install a laser tube.

[quy.ngo]

One article recommends that you use terminal connectors to wire the tube but another says the proper way is to use the wire wrap technique to join the 2 wires. Also I didn't get silicon tubing with my laser power supply or tube and I'm wondering if it is okay to use the compressor hose that came with my compressor. 

Terminal connectors

Feed high voltage and ground wire in to the enclosure through the same hole. Solder on spade terminals on to both wires. Be sure to use plenty of solder on the high voltage spade terminal to reduce corona discharge and risk of arcing. Squeeze both terminals slightly with a pair of pliers to decrease the spade terminal loop diameter. Wrap both terminals with plenty of electrical tape, excluding the front of the connector. Note that every wrap of electrical tape is rated at 600 volts. Push connectors on the laser tube electrical connections. The connectors should be fairly snug. If not, disconnect and squeeze the spade connecter again with a pair of pliers. Do not solder to the tube. Not only does it make it difficult to replace the tube, you risk fracturing the tube as the glass on the tube will expand unevenly as you heat it with the iron.

The 100W tube already has terminals and insulation. It's super straight
forward, no extras required.

I wanted to start with the 40w and work my way up to 100w. With the 40w power supply only came with the high voltage line.

I eventually found 2 more articles basically one said that there are many ways to attach the -/+ voltage lines and there really isn't a best way just whatever works for you.
