EW-D Handheld Welding Machine
The EW-D handheld laser welding machine is specially designed to minimize accidental exposure to hazardous radiation. To ensure safe operation and optimal performance, please follow these prompts and warnings:
Warning: When using this laser device, ensure that the safety ground wire is connected.
Attention: Before powering on the laser device, confirm that the input is either 220V or 380V AC power, as indicated on the device nameplate. Using incorrect voltage may damage the device. GH-Smart Laser Engraving Machine The GH-Smart laser engraving machine produces a high-brightness, high-power, and high-energy beam of light. Intense laser irradiation can cause skin burns. If the laser is directed into the eyes or reflects off a bright surface, it can result in permanent eye damage or blindness. To prevent accidental injury, avoid placing any part of your body in the laser's path.
GH-Smart Laser Engraving Machine
Laser is a high brightness, high power, and high-energy beam of light. Intense laser irradiation can cause burns to the skin of the human body. If directly shot into the eyes or reflected from a bright surface, it can cause permanent damage to the eyes until blindness. It is advisable to avoid placing any part of the body in the laser path to prevent accidental operation and injury.
Safety Requirements for Equipment Operation
The user may operate the laser device only when all external adjustments (such as electricity, temperature, and auxiliary gas) and protective measures are normal.
Carefully read the user manual and pay attention to the safety precautions it contains.
Special laser protective goggles must be worn before performing any laser operations.
During operation, always ensure that your eyes and any part of your body do not become exposed to the light path emitted by the laser.
While using the equipment, regularly check that safety measures such as protective grounding, safety interlock switches, and emergency stop buttons are functioning properly. If any abnormalities occur, immediately cut off the power for inspection and maintenance. When carrying out repairs, refer to the relevant content in the manual and have qualified personnel perform the work.
It is prohibited to use ordinary welding protective glasses or sunglasses instead of specialized laser protective goggles, as this can cause more damage to the retina than exposure to naked eyes.
Power interruptions pose a significant threat to lasers; therefore, ensure a continuous power supply. The laser power supply box contains high-voltage components, and disassembly is prohibited during equipment operation.
