Safety First: 5 Protective Measures that cannot Be Ignored when operating 3KW Handheld Laser Welding Machine
Dec 22, 20251) Eye protection: Special laser protective glasses must be worn. The protection level should be matched with a laser of around 1060nm (common handheld welding wavelength), and the optical density (OD) value should be high enough.
2) Skin and body protection: Wear professional laser welding protective clothing (flame-retardant and sputtering resistant), insulating thick gloves, and ensure that there is no exposed skin on the body.
3) Respiratory protection: A powerful exhaust system with high-efficiency particle filtration (HEPA) function must be used or air-supplied respiratory protective equipment must be worn.
4) Operating Environment and Fire Prevention: Clean the operation area and remove all flammable and explosive materials (oil, paint, gas cylinders, etc.). Prepare fire extinguishers and set up fire prevention monitoring.
5) Equipment Safety and Training: Strictly train before taking up the post to ensure that operators are familiar with the emergency switches and safety interlock functions of the equipment. The equipment must be grounded and the insulation of the cables and joints should be inspected regularly.
Advanced Security Practices
1) Set up a physical isolation zone: Install laser safety protection fences or curtains in the operation area and post prominent laser radiation warning signs to prevent unauthorized personnel from entering by mistake.
2) Implement the "two-person operation" system: Especially in complex or high-risk environments, one person operates while the other is responsible for supervising the safety status and being ready to activate emergency measures at any time.
3) Strictly conduct equipment inspection: Before each use, check whether the laser output head, protective lens, cooling system, and air pipe wires are in good condition. Lens contamination can greatly increase the risk of reflection.
4) Pay attention to the particularity of materials: Some materials (such as galvanized steel and aluminum alloy) can produce more toxic smoke and dust or stronger reflection, and additional ventilation and protection measures need to be strengthened.
The Golden rule for Safe operation
1)Always assume that the laser beam and the processing area are in a "dangerous state".
2) Never point the laser head at anyone, even if the device is not emitting light.
3) When the welding risk of the material is uncertain, conduct a test weld with a small parameter first and enhance protection.
4) Any damaged safety equipment should be replaced immediately without any compromise.
