Reci W4 S4 Z4 100W Max.130W CO2 Laser Tube Wooden Case Box Packing Length 1400 Dia. 80mm for CO2 Laser Engraving Cutting Machine
Mark & Model: W4, The product is featured as small size and good model, higher power rate compared with the laser tube of similar
length and longer service time, which is suitable for laser marking, laser cutting and laser engraving.
1. Installation Requirement:
Make sure to follow the operation instruction of model W4 as shown in the illustration. The dedicated power P14 should be
equipped. The positive pole of laser tube is in high voltage (the ignition voltage is 24kv). It may cause the following
consequence when it is failed to follow the instruction: Arcing; the inner tube will be punctured by electricity and may cause
water leakage.
2. Operation conditions:
Water cooling: using purified water; 3 to 5 liter/minute; water temperature: 10鈩�-40鈩�.
The operating environment: temperature 2-40鈩�; Humidity 10-60%.
The working current: test current is 30mA. Maximum working current is 30mA. The running current must be kept below 28mA. The life
span can reach 10,000 hours if the current is kept below 26mA. The ammeter must be connected to the negative electrode of laser
tube.
When it is working under over-high current for long term, the negative pole will appear light yellow and the life span will be
shortened rapidly.
To protect dust from going into the insulation sheath, please wrap it with plastic film.
3. Working Performance:
Cutting function.
Engraving function: Very good. When the working current is 4mA and the tube is in the state of preionization, the laser can be
used for high-frequency impulse engraving.
4. Key Notes:
Do not clean the exterior surface of the output widow mirror with tools such as tampon; otherwise the output power will be
seriously affected. The followings are the designated methods to clean up pollution in the exterior surface of window mirror:
1) When the mirror is polluted, do not turn on the laser.
2) Blow the mirror surface sideways with an air blower.
3) Spray the pure alcohol on the mirror surface with sprayer.
4) Turn on the laser after the alcohol gets fully volatilized.
5) If the methods above don't work effectively, it is necessary to ask for the professional to use tampon with alcohol to clean
the mirror surface from middle to edge. The best solution is to prevent the window from being polluted.
Attention: it is forbidden to clean the mirror with acetone.
The screws in the front and back ends of the laser tube are not allowed to be moved, otherwise the output power will be declined,
even the tube will be scrapped.
Put the acryl 300mm far away from output mirror, when testing its laser spot.
5. Safety:
The laser beam is invisible light. Please wear protective glasses when debugging the laser. The positive pole is in high voltage.
Pay attention to the security marks.
6. Storage and Transportation Requirement:
Pour out cooling fluid in the event of storage and transportation, and cover the output terminal with a dust-proof plastic bag.
The storage environment is 2-40鈩�, and the requested humidity is 10-60%. Pack the laser as in the original way.
Important notes: it is requested to use adhesive tape to cement the sponge together with laser tube to prevent the tube from
vertically sliding during transportation. The sponge in the side of output mirror must be 70 mm beyond it, and the sponge in the
side of reflecting mirror must be 50 mm wider.
7. Tubes operated in wrong way are not guaranteed by Manufacturer.

Works, and no residue!
Style: SPF 50 (Pack of 2), Size: 5.5 Ounce (Pack of 2)
I love that I can just use my FSA account to buy this.
The sunscreen works well and does not irritate my kids sensitive skin. What I like the most is that it does not leave residue everywhere so I can do a quick spray on the kids every morning before daycare. I also spray my son's head because he has a very fair skin and does not wear a hat at daycare.
It seems to be doing well by the pool too.
Good value pack.

Must have sunscreen for kids!
Style: SPF 50 (Pack of 3), Size: 5.5 Fl Oz (Pack of 3)
This is our favorite sunscreen. It is easy to apply stays on and my kids do not get burned. I have a 9, 8 and 6 year-old we live in Florida and this is the only sunscreen we buy for their body. It does not cause any skin irritation.

Lightweight and non-greasy
Style: Sensitive Skin, Size: 6 Ounce (Pack of 2), Style: Sensitive Skin, Size: 6 Ounce (Pack of 2)
It doesn’t feel heavy or greasy on the skin, and I really like the scent. It absorbs well and does its job protecting from the sun. I sent these to Cuba, where the sun is very strong, and my mom is really happy with the results. Overall, a great sunscreen.

Fantastic sensitive skin mineral lotion
Style: Sensitive Skin, Size: 6 Fl Oz (Pack of 2)
Mineral sunscreen is required in Hawaii. They don't allow the chemical variety as they are trying to protect the reefs. The Banana Boat Sensitive 100% Mineral Sunscreen Lotion SPF 50 Twin Pack is a great option for reliable, gentle sun protection. Made with 100% mineral actives, it’s perfect for sensitive skin and provides strong broad-spectrum coverage against UVA and UVB rays. The lotion is lightweight, blends in well without leaving a heavy white cast, and feels comfortable for all-day wear. It’s also water-resistant, making it a dependable choice for outdoor activities. With the value of a twin pack, it’s a smart buy for keeping your skin safe and protected. We used it in Hawaii and it was popular among our crew. It didn't last long!

On my Safe List from allergist!
Style: Sensitive Skin, Size: 6 Fl Oz (Pack of 2)
I like this product because it is nice and creamy, has no odor, it rubs in easily and it stays on. I need constant sun protection every day and this one seems to provide it, even when boating. I have no itching or irritation of skin or eyes after using. So much better than a sticky spray that feels like a plastic coating when it dries. I am getting better protection with this one, and you don’t feel like you’ve gotta wash it all off at the end of the day. Very happy I tried it, and I’m going to stick with it.
