4.3 Welding Process
- Select the appropriate welding parameters (power, scan width, wire feed speed) based on the material and thickness.
- The welding gun is designed for 360° welding and can be used at various angles.
- For materials like stainless steel, carbon steel, and galvanized sheet, the single-side melting depth can reach ≥5mm. For aluminum alloy, it is ≥4mm, and for titanium alloy, it is ≥5mm.
- The auto wire feeder can be engaged for stronger welds or when filling larger gaps. The feeder function can be turned off if not needed.

4.4 Weld Seam Cleaning
After welding, switch to the cleaning mode to prepare the surface for painting or to improve the aesthetic finish. This process enhances adhesion during subsequent treatments.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your laser welding machine.
5.1 Cleaning the Welding Gun and Lenses
- Periodically inspect the welding gun nozzle and protective lenses for dirt or damage.
- Clean lenses with appropriate optical cleaning solutions and lint-free wipes. Replace damaged lenses immediately.
- The red warning reminder on the welding head indicates when the inner lens may be dirty or the temperature is high, prompting necessary cleaning or cooling.
5.2 Water Cooling System Maintenance
- Check the water level in the tank regularly and refill with distilled, deionized, or pure water as needed.
- Replace the cooling water periodically (e.g., every 3-6 months, depending on usage) to prevent algae growth and maintain cooling efficiency.
- Clean the cooling system filters if present.
5.3 General Machine Care
- Keep the machine exterior clean and free of dust and debris.
- Inspect all cables and connections for wear or damage. The outside cloth of the cable is designed with flame-retardant fabric for added safety.
