3, power box with high pressure on many places, after power on, hand can't touch the metal parts of the device;
4, Before replace the power box inside device ,turn off the power supply of the energy storage capacitor shall be discharged completely and voltage profile after confirm no voltage for the next step of replacement or repair measures;
5, if the laser machine works unstable, or fall of work, can check circuit screw, terminal blocks, such as whether is loose,
wiring the phenomenon such as oxidation.The old power supply or the power supply works under poor environment ,pay more attention on formation condition;
6 ,when maintenance,don't tear down the internal cable tie and connecting wire, control panel, or cut disorderly change, is likely to cause the whole machine interference or performance degradation, and even cause scrap.

Fault Analysis of CO2 Laser Power Supply Not Working:
CO2 laser power does not work
(1) Maybe overvoltage protection action:
A. Please check whether the power supply output and the positive connection of the lamp are reliable!
B. may be damaged or lamp tube aging, breakdown voltage exceeds 35KV.
(2) Check that the AC input cable and the control wire are securely connected.
(3) Check the high-voltage output line for damage, leakage may lead to power in the work, but the lamp is not light!
(4) Power ground wire (not the power output of the black line but the first port of the AC input terminal see page 3 of the
manual) is correct and reliable access to the earth.

Daily Drinker Warning: Great Energy, but Watch Your Teeth!
Set name: Orange Cream
No sugar which is great and this energy drink has become a staple but it is also very acidic so watch out if you have very thin teeth like me. I often find it increasing my sensitivity by a lot so a sensitivity toothpaste daily is essential for me since I drink these daily.
The feeling or energy from these is great, I have been drinking similar ones like G fuel for years and this gives me significantly more energy. A quick tip though is many dollar trees have Gfuel available so if you need sugar free energy drinks like me, they provide cheaper deals - currently dollar tree has G fuel for 1.25$ a can which is quite cost effective compared to Ghost.
Drinkability is mixed with Ghost, they are strong drinks. I often find G fuel being very refreshing and enjoyable while Ghost is very concentrated.
Comparison - Gfuel vs. Ghost ingredients and focus
Ghost:
Focus - Cognitive function, energy metabolism, and premium/transparent sourcing.
Caffeine - Natural from coffee beans
Nootropics - Alpha-GPC, NeuroFactor™ Coffee Fruit Extract.
Performance - Carnipure® L-Carnitine L-Tartrate, Taurine.
What makes it unique - AstraGin® (absorption enhancer), transparent proprietary blends.
Sweeteners - Sucralose, Acesulfame Potassium.
Gfuel:
Focus - support for focus and antioxidants.
Caffeine - synthetic
Nootropics - L-tyrosine and L-theanine
Performance - Taurine, L-citrulline malate
What makes it unique - Extensive Antioxidant Complex, high dose of Vitamins C, E, and B-vitamins.
Sweeteners - Sucralose, Acesulfame Potassium.
The bottom line here: G Fuel for maximum boost and vitamins; Ghost for premium, clean, and focused energy. Ghost is mostly proprietary blends of vitamins which is something to keep in mind since we do not know what is in them while G fuel is more transparent for the most part. I recommend trying both and seeing what works best for you.

Best Blue Raspberry energy drink out there!!
Set name: Blue Raspberry
I've tried multiple different brands of energy drinks that have blue raspberry as a flavor. My absolute favorite was the C4 Jolly Rancher Blue Raspberry energy drink..... UNTIL I tried this one. Beats it for sure. It has such a sweet, smooth and refreshing taste and gives a solid boost to power me through my day. The price is a little high but in all honesty it's worth the money! No crash or jitters after one of these and this is coming from someone who drinks lots of caffeine every day. TL;DR absolutely worth a try!!

Great flavor and solid energy boost
Set name: Cherry Limeade
By far my favorite flavor in any energy drink. GHOST really does this one well and the Cherry Limeade tastes great compared to a lot of other energy drinks I’ve tried.
Yes, it is high in caffeine, but that’s actually what I need sometimes for a real energy boost, and this one does the job without feeling overly heavy. The calorie content is also great if you’re someone who watches calories, which I appreciate.
Overall, great flavor, solid energy, and one of my go-to energy drinks.

Compact snacks you won’t give back!
Flavor Name: Variety, Size: 29 Ounce (Pack of 1)
Super tasty! I actually didn’t realize I could get something like this since most in person stores I’ve never seen these specific combo of flavors together. I personally love the pretzels and getting them in actual lunch snack sizes for work or just to grab for a quick snack on the go is the best thing and makes my day! Perfect size to fulfill a craving and there’s plenty in there even for 2 kids or adults to take to school work or just a tasty on the go snack! Pricing was great for the size and amount of snacks you get and definitely still has that flavorful salty delicious good fish crackers taste while still being fresh and providing that perfect crunch and texture of the regular or jumbo box version.
