Anti-freeze Maintenance of Laser Source
1.If there are frequent power outages and the conditions for emptying the coolant every day are not available, antifreeze must be used. The base liquid of antifreeze is generally composed of water and alcohols. It requires high boiling point and flash point, high specific heat capacity, good heat conductivity, low low-temperature viscosity, not easy to foam, and does not corrode metal parts and rubber hoses. When selecting and preparing antifreeze, its freezing point should be 5 degrees Celsius lower than the lowest environment temperature.
2.Recommended antifreeze brands.
CLARIANT. There are two models suitable for laser systems:
1)Antifrogen RN glycol-water type (industrial product, harmful to human body)
2)Antifrogen RL propylene glycol-water type (food grade, harmless to the human body)
Note: Any antifreeze cannot completely replace deionized water and cannot be used for long periods of time throughout the year. The volume used accounts for 10%-20% of the water tank volume and cannot exceed 20%. After winter, the pipes must be cleaned with deionized or purified water and restored to their use as coolant.
3.When the ambient temperature is too low, the water chiller must be turned on 24 hours a day.
4.If the equipment is not used for a long time, the cooling water needs to be drained. Use clean and dry gas (pressure less than 0.5MPa) to dry the water in the pipeline.
Precautions for Using the Cladding Head
1.Avoid plugging and unplugging optical fibers unless necessary. When necessary, make sure the surrounding environment is clean, clean your hands or wear rubber gloves before performing horizontal plugging and unplugging. After the optical fiber is pulled out, use a protective cap to protect it. After the optical fiber is inserted, wrap the interface with paper tape to avoid contamination.
2.Check whether the protective lens is clean before each use, and wipe or replace it if necessary (see the user manual for details). This process requires sealing the protective lens drawer opening and the light hole at the bottom with paper tape to prevent dust from entering the interior of the cladding head.
3.Check whether the light path is blocked before each use and remove obstructions.
4.Check and adjust before each use to ensure that the focus is correct, the spot size is appropriate, and the spot and powder are in the appropriate position on the workpiece.
5.Check whether the powder is evenly distributed before use. If it is uneven, adjust the powder feeder or clean the powder feeding nozzle.
6.During use, ensure that there is always gas protection, and the protective gas pressure and flow rate are appropriate; it should also be clean and dry.
7.Pay attention to the protection of the cladding head during use to avoid damage to it due to collision, reflected light, etc.
8.Every 1.5-2 hours of work, the operator should check whether the temperature of the cladding head is abnormal. If there is any abnormality, please stop the machine in time and contact our after-sales personnel;
9.Clean the dust and powder on the laser cladding head after use. And seal the light outlet with paper tape to prevent dust from entering.
10.If the cladding head needs to be dismantled for transportation, please use clean and dry gas to dry the water in the water pipe, blow out the powder in the powder pipe, and take anti-shock protection measures.

1.The protective lens must be from the original factory, otherwise the quality problems of the cladding head will be borne by the customer!
2.The parts of the cladding head including upper protective lens, lower protective lens, collimating lens, focusing lens, powder feeding nozzle, baffle and pan plug seal are all wearing parts. Their lifespan will vary depending on length or method of use. They are not covered by the warranty.
Precautions for Using Gravity-fed Powder Feeder
| The powder feeder has been installed and debugged before delivery. Do not disassemble or change settings at will. (As shown on the right) |  |
| Connect one end of the powder feeding tube to the powder outlet interface at the bottom of the gravity powder feeder, and the other end to the powder inlet of the powder feeding nozzle (it is recommended to use a special anti-static PU powder feeding tube). |  |
| The front panel of the powder feeding controller is fixed on the right of the cantilever (see the picture on the right). After the equipment is powered on, press the power switch and the indicator light will light up. Change the voltage by adjusting the “armature voltage adjustment knob” to adjust the powder feeding amount. |  |
| Precautions: 1. Before use, the alloy powder should be baked at 100-150°C for 30-40 minutes and sieved with a sieve. Then put it into the powder feeder and tighten the powder top cover. 2. The manufacturing process and particle size range of the powder will affect the powder feeding accuracy. Atomized spherical alloy powder and alloy powder with a small particle size range have higher powder feeding accuracy. Please use spherical powder with appropriate particle size, otherwise the powder path will be blocked due to poor powder fluidity. 3. When not in use for a long time, please clean the powder feeder and blow it clean with dry airflow. It is recommended to use dry high-pressure air to clean the entire powder circuits every month. 4. The powder storage cylinder is fragile and should be protected with care. 5. Avoid powder contacting electrical components and causing short circuits. 6. All parameters of the powder feeder have been set before delivery, and users are not allowed to disassemble it without permission. Quality problems caused by unauthorized disassembly shall be borne by the customer! | |
Note: The powder barrel of the powder feeder and the powder dividing wheel are wearing parts, and their service life will vary depending on the length of use or method of use. Therefore, all consumable parts are not covered by the warranty.
