• The output head of the laser is connected with the optical cable. Please utilize unique lens paper when cleaning the output lens.
• The laser may be damaged by the inappropriate operation of the laser is not used as specified in this handbook.
• When the laser is in operation, it is forbidden to set up the output head.
• Do not view the output head directly. Make certain to wear laser defense when running the machine.

Preventative Measures

• Before the laser welding device is connected to the Air Conditioning power supply, it is essential to ensure that the right 380V Air Conditioning voltage is connected. The wrong connection of the power supply will trigger irrecoverable damage to the laser.
• Failure to operate the laser by the control or change methods specified in this handbook may trigger damage.
• It is essential to keep the output lens clean for the laser output with good collimation. Otherwise, the laser will be harmed irrecoverably.

Devices Preparation Before Use

Cooling system water temperature level setting: In summer (ambient temperature level greater than 30 ℃) 29 ± 0.5 ℃.

In winter (ambient temperature level below 30 ℃) 25 ± 0.5 ℃.

Coolant requirements:

Cleansed water is used as cooling water, and drinking cleansed water is suggested.

To avoid the pipe blockage caused by mold growth in the chiller’s water, it is suggested to include ethanol when adding distilled water, and the volume ratio of ethanol is 10%.

When the ambient temperature of the equipment is between– 10 ℃ and 0 ℃, 30% ethanol solution by volume must be utilized and replaced every 2 months.

When the ambient temperature level of the devices is lower than– 10 ℃, the double system (with heating function) chiller must be used, and the constant operation of the cooling system should be guaranteed.

Other requirements of the cooling system:

The cooling water inside the cooling system and the laser ought to be drained pipes if the laser is not utilized for a long time. Otherwise, it will cause irrecoverable damage to the laser devices.

Set the water temperature level of the cooling system correctly according to the ambient temperature. The laser will not usually work if the water temperature level is set too high. If the water temperature level is set too low, the condensed water will be produced in the laser or in the laser output head, which will cause irrecoverable damage to the laser.

Before starting the laser, the cooling system needs to work generally, and the water temperature level should reach the appropriate temperature. (summer season: 29 ± 0.5 ℃; winter: 25 ± 0.5 ℃).

Installation Precautions

The devices will be put in a correct position horizontally and repaired as essential.

Before the equipment is powered on, please check whether the power supply is steady (220-380vac ± 10%, 50/ 60Hz) and whether the grounding wire is in good condition.

All power lines and control lines ought to be linked well in the state of no electrical power.

Link the cooling system to the laser and output head according to the water inlet and outlet recognition.

Please examine the laser output head and clean it as required before installing it into the equipment. Do not continue to operate the laser and set up for the time being if dust is discovered on the output head.

Do not step on, squeeze, or overbend the Yellow/metal armored protective sleeve during jumper set up to avoid damage to the fiber optics.

In the installation and removal process, please manage the laser output head with care and avoid vibration.

In the procedure of installing the jumper output head, the surrounding environment must be clean. Otherwise, it may pollute the output head (when hot every day in summertime, do not use an electric fan to dissipate heat to avoid large dust in the air).

The minimum bending radius of the transmission fiber of the laser should not be less than 20cm under non-working conditions such as transportation and storage. In the laser output state, the minimum bending radius will not be less than 30cm.

All the control lines of the laser must be connected in a non-electrified state. The charged setup of the control line might trigger damage to the laser.

The laser output fiber needs to be placed in a natural state as far as possible, and it is forbidden to twist the output fiber.

If the size of the fiber is too small, the output of the laser will be damaged.

In setup and elimination, please manage the laser output head with care and avoid vibration.

Before the laser output head is put together, the optical lens and cutting head cavity must be pollution-free and tidy.

Please take great care of the protective cap of the output head to avoid it from being contaminated; otherwise, the protective cap will trigger indirect contamination to the output head.
