Connect the other end of the grounding wire securely to the outdoor grounding pole.
4- Securely Lock the Connection
Ensure a Secure Connection Before Activating the Laser
Prior to switching on the laser, it is crucial to attach the safety lock to the loop
interface of the laser device. During laser preparation, fasten the other end of the
safety lock (alligator clip) onto the workpiece. This ensures that the alligator clip and
the welding head form a complete loop, allowing the laser to function properly and
output laser energy safely.
5-Safely Secure the Gas Connection
The welding head is cooled by inert gas, which requires maintaining optimum gas
purity and air pressure. Typically, nitrogen and argon serve as shielding gases. The
shielding gas purity must be 99.99%, and the input gas pressure should range from
80Kpa to 500Kpa. For an effective welding process, it's essential to use a pressure-
reducing valve with a flowmeter (nominal flow rate of 25L/min) to accurately control
the airflow.
