Handheld laser welding machine welding gun maintenance and operation guide

 Maintenance of the welding gun of the handheld laser welding machine:


1. Regularly check and replace the contact tip:


As the aperture of the worn contact tip becomes larger, the arc will be unstable, the appearance of the weld will deteriorate or the wire will stick; the end of the contact tip will stick to splashes, and the wire feeding will become uneven; the contact tip is not tightened, The threaded connection will heat up and weld to death.



2. Regularly clean and replace the spring hose:


After a long time of use of the spring hose, a large amount of iron powder, dust, welding wire plating swarf, etc. will accumulate, which will make the wire feeding unstable. Therefore, it is important to clean it regularly. You can curl it and tap it lightly to shake off the accumulation, and then blow it off with compressed air. Use a brush to scrub the grease on the hose in the oil, and then blow it off with compressed air. If the spring hose is wrongly threaded or severely deformed and bent, replace it with a new hose. When changing the tube, make sure that it is suitable for the diameter and length of the welding wire used, and there should be no burrs on the cut surface.


3. Inspection of insulating ferrule:


If the insulating ferrule is removed for welding, splashes will adhere to the inside of the nozzle to make the nozzle and the live part conductive. The welding torch may burn out due to a short circuit. At the same time, in order to make the shielding gas flow out evenly, an insulating ferrule must be installed.


Hand-held laser welding machine operation guide:


1. The hand-held laser welding machine must be professionally trained to understand the use of system indicators and buttons, and be familiar with the most basic equipment knowledge, safety knowledge, and precautions before using it.


2. Inspection work before hand-held laser welding machine. Wire ducts and wires are undamaged and exposed; robot body, external shaft, gun cleaning station, water cooler are strictly prohibited from placing sundries, tools, etc.;


3. It is strictly forbidden to place liquid objects (such as water bottles) on the control cabinet; no flammable objects (such as cotton shoes) in the operating room; the temperature of the operating room must not exceed 25 degrees Celsius; no air leakage, water leakage, and electrical leakage; the welding tool thread is not damaged, the robot No abnormality; There is no magnetic field or vibration source (such as a magnet) in the working range of the robot.
