  • Page 6: Chapter 1 - General Safety Information

    Chapter 1 – General Safety Information 1. Safe use of Handheld Laser Welding Machines • Handheld laser welding machines are classified as hazardous, invisible laser radiation Class 4 laser products. This product emits infrared laser radiation with a wavelength of 1080 nm, and the average power radiated by the welding head is greater than 100W, which can cause damage to eyes and skin directly or indirectly exposed to such light intensity.

  • Page 7: Signals Explanation

    and humidity can cause a short circuit, affecting the normal use of the laser and provoking potential safety hazards Do not expose the welding machine to excessive humidity The laser head is air cooled. Please ensure that the ambient air is dry and clean Operation or adjustment beyond the scope specified in this manual may result in dangerous radiation injury Keep the welding area clean.
  • Page 8 Warning Note: A warning symbol shows a potential product hazard. It points out an operating procedure that, if not followed correctly, can result in damage or destruction of the product or a component. Laser Welding Room Note: If someone enters unexpectedly into the welding cabin, the interlock automatically shuts down the welding system.

  • Page 10: Weld Safety Hazards

    4 .Weld Safety Hazards • • 1 -Eyes and Ultraviolet Radiation Hazard Visible and invisible radiation is generated during welding. The interaction between the high-power laser beam and the target material to be welded can create a plasma that generates ultraviolet radiation and “blue light,” which can lead to conjunctivitis, photochemical damage to the retina, or a sunburn like reaction to the skin.

  • Page 11: Safety Guidance

    5 -Cylinder Safety • The gas cylinder may explode if it is damaged or placed too close to the welding area. A gas regulator suitable for the required gas and pressure is essential. All hoses and fittings should also be in good working condition and suitable for the application.
  • Page 12 WARNING: If the product is not used in compliance with the instructions the protection mechanism provided may be affected. This product must and should only be used under conventional conditions. CAUTION: When operating laser welded output cables (such as installing optical cables, using optical instruments, etc.), be sure to keep AC power off.
  • Page 13 particles, and sparks. All personnel working near laser welding areas must also wear personal protective equipment. WARNING: Take protective measures to prevent skin damage. Wear protective clothing, such as laser/heat resistant gloves, hats, leather aprons, protective clothing, etc. Button sleeves and necklines up. WARNING: If flammable materials are near the welding area, the heat and sparks generated during welding may cause a fire or an explosion.
  • Page 14 not try to look at that area nor place any part of your body inside the expected specular cone. WARNING: Operators and people passing by must also be aware of reflections. If the laser parameters are not set properly to achieve melting of the workpiece, more reflection may occur.

  • Page 16 When the device is powered on, do not directly observe the laser torch, neither the output optical fiber nor the welding connector. Always wear safety glasses and a welding mask when handling the product. The people nearby must also wear the same safety gear. Ensure that all personal protective equipment is suitable for the power output and wavelength range listed on the laser safety label attached to the device.

  • Page 17: Electrical Safety

    9- Electrical Safety • WARNING: All electrical and welding gas connections must be checked before supplying power to the unit. Also, if applicable, all connections must be secured with screws to ensure proper function. All electrical and welding gas connections must be connected before power is supplied to the unit.

  • Page 18: Reference Standard

    The laser may be damaged unless careful handling of equipment. Refer to the product specification for more information. This device is not to be used where unprotected people may be present. Keep away from shock or vibration sources. Appropriate protective measures should be applied to ensure a laser- safe working area.

  • Page 19: General Safety Instructions

    WARNING: The output laser beam intensity of Ronch handheld laser welding machine is enough to weld metal, burn skin, clothing and paint, and ignite volatile substances such as alcohol, gasoline, ether, etc. Therefore, during operation and use, be sure to remove the flammable items around the welding area.
  • Page 20 9. Operate the equipment strictly in accordance with the instructions in this document, otherwise the protection device and performance of the equipment will be impaired, and Ronch warranty will be voided. NOTICE: The optical output of the handheld laser welding machine will be sent out after passing through a lens with an anti-reflection coating.
