Troubleshooting DaDo "Error r4" (Flow Failure)
If your DaDo 1 laser welder is flashing Error r4 (Flow Failure) on the display screen, it indicates a critical issue within your water cooling loop. Before purchasing a new tank assembly, we recommend checking these common fault points:Low Water Level: Inspect the water level indicator window in the chamber and top up using de-ionised water if necessary.Cooling Line Blockage: Check for kinked tubes or biological buildup within the internal water hoses.Physical Tank Failure: Inspect the aging plastic seams or the integrated feed assembly for cracks and leaks.
Service & Installation Options:
For older generation machines encountering persistent flow issues, you have two pathways to resolve the problem:DIY Installation: Order this replacement water tank kit directly and complete the swap yourself using our guided documentation.Factory Service Option: Send your machine to our technical center for a comprehensive cooling overhaul. Our team will replace the internal tank, fully test the loop, and return the unit for a flat rate of £220 + VAT (includes return shipping).

Bending and feeding loose laser wire can be an awkward, inefficient struggle. The Speedwire pen allows you to easily hold and control your wire feed. By keeping your hands further away from the laser target area, it significantly improves operator safety and eliminates heat transfer from the wire to your fingers.
Dispense more wire instantly and smoothly. The wire remains perfectly positioned for firing, maximizing your speed, accuracy, and overall laser welding efficiency.
