Laser Tube Wire Connection and Electrical Leak Troubleshooting Tutorial

Laser Tube High Voltage Wire Connection Tutorial
Video show how to properly connect 40,000V red wire to CO2 laser glass tube. High voltage wire from power supply will leak an arc and spark all over the place if not properly insulated. Electrical tape will NOT hold arc will go through it very easily. (3M tapes are only rated up to 600V and laser has 40000V)
To properly insulate a disconnect in high voltage wire you need to boot it into silicone or glass tube , and that tube needs to extend more them max lengths of the arc. This will prevent leakage to the body of machine of to any closes grounded object.
Before working with laser wiring, keep in mind that power supply hold charge even after it’s disconnected! Let capacitors discharge before you touch wires! Ware proper PPE, do not work in wet of flooded areas.

Thank you for this Video! It was a huge help.

Glad it helped!

Thank you for the instruction video. I'm replacing my tube confidently now!

Thank you sooooo much for this video tutorial! I will follow your instructions! Very, very, very good video!!!

Can i use solder to then electric tape then use pipe thats with chiller

[@lasercutzinfo4718]

yes u can solder BUT twist wires before you solder as if wire get shot it will melt solder and wires will separate so twist will hold them in place. Electrical tape is mostly for water/moisture/humidity insulation so make sure silicone tubes covers far enough form a disconnect point, silicone form chiller is perfect choice.

Then this cable it is supposed to be wrapped with tape in tube?

[@lasercutzinfo4718]

red cable splice, wrapped by electrical tape, then silicone goes on top and and extra electrical tape on sides on tube

I do those steps everytime , machine runs fine 3 to 4 houres and then start again and burns everything :(

[@lasercutzinfo4718]

if u see same synptoms of high voltage leak, arc from wire to body/ground after few hours then check hymidity, check wire temp (contact less ir thermometer). if humidity increasing or water leaks from tune it can conduct electricity. if wire gets hot it may expose crack in shielding. both scenarios are not too mych likely but phisics is phisics . other thing to check is ur ground. if some how electric flow does not go though tunbe or its ground wire it will try to find nearest and weakest exit point. ex bad ground wire or some how electrical defect in power supply that increases resistance on groumd. what i seen on our own machine was leakage from flyback transformers, ex as power supply gets hot flybacks start shooting lighting to power supply body (inside). so bottom lime if wires leaking replace all, really all wired. if does not help replace power supply, if does not help look at what u could possibly miss in symptoms :)

@@lasercutzinfo4718 ur right i guess I did wrong instead of cilicon pipe as protection i used plastic pipes . For now I did changed to cilicon pipe to cover attached area . And for humidity yes can be a factor too . As I living in tropical weather country very high humidity level 😑 . Tqvm for explaining

[@lasercutzinfo4718]

plastic pipe can work but depends on plastic ex abs can absorb moisture which is irrelevant to most cases but when comes to high voltage it can become a conductor.
so yes, try silicone and as long as possible to to isolate any unexpected exit point
