💡 Key Repair & Operation Instructions:

  • Thermal Dissipation Handling: Copper alloys conduct heat rapidly away from the weld zone. Preheating or using higher laser pulse peak energy is essential for seamless fusion.
  • Safety Note: Ensure proper local exhaust ventilation during TIG grinding or welding to minimize fume inhalation.
