MCWlaserSet of 2 High Voltage Wire Connector Between CO2 Power Supply and CO2 Laser Tube for Laser Cutting Machine high Voltage Head

These are great HV connectors for your CO2 laser tube, either new or replaced as some units arrive without any connectors on either the cathode or anode connections. These ensure you get a solid electrical connection without the risk of flashover or leakage due to the high voltage present. My laser supply is running at 13KV and you don't want any stray current paths. These are easy to install and provide great HV protection.

This worked great to replace the one I had to cut off of the old tube. Great quality, and it shipped with Prime so I had it super quick. We are looking to upgrade to a higher watt tube sometime soon, so this will be the connector I will use again.

First off, there are no instructions. You get to figger it out. You have to slide on the black pieces first. The problem with that is that the typical high-voltage wire has a diameter of about 4mm, and the hole in these black rubber pieces is about half that. You can't just slide these on and off easily. I used a bit of petroleum jelly to lubricate the wire and the hole. The jelly is non-conductive, so don't worry about that! Once on, the black pieces have to be slid down about 6 six inches to make room for the rest of the process. Next come the white tubes. Once these are over the wires, you can then connect the little pin and socket pieces. You have to back out the screw first, carefully or it will pop-out and you might lose it. Look down the hole as you do this. Then with your wire stripped to about 3/8 of an inch, insert the wire into the side with the screw and tighten it down. I used the female (socket) side on the power-supply wire, and the pin side on the wire to the laser tube. These then slide back into the white pieces and then you have to wrestle the black pieces back over the top of the ends of the white pieces. Then the two sides just connect together and twist on the threads. Hope that helps. You can do it!

These make installing a prewired laser tube simple and safe. I put a 50w tube in my K40, and these assured that I didn’t electrocute myself in the process.The rubber pieces are TIGHT, but they need to be in order to do their job. I’ll definitely order again.

Muy práctico y buen acabado, con un video demostrativo excelente, lo utilicé para entender un cable alimentado a 27 Kv. Gracias.

My K40 laser didn't come with a disconnect on the high voltage line. This installed quickly and easily and will make any future tube replacement much quicker and easier.

One of the connectors clearly has what appears to be scorch marks on the end. Since these are high voltage connectors, I guess I won't be using that one. Didn't notice until one was already installed so I won't be returning it.

It appears to be a nice product, but I have a co2 laser with a possible 30kv potential. The only high voltage wires I've found were 20kv or 40kv. The 40kv are 5mm in diameter and the connector has a 4.55mm hole to feed it though. So at this point I'm stuck. Do I search for the proper size wire or proper cable?It would be nice if measurements were prominently displayed.Ordered the proper size wire.
