Do you know some ways of maintenance of handheld laser welding machine?

 Maintenance of welding gun of 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 become 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 the spring hose is used for a long time, 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 the 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.handheld laser welding machine

The Best Solar Power Batteries On The Market

One of the best ways to reduce your reliance on fossil fuels is to use solar power. You'll want to consider buying a battery system that is designed for solar power in order to store excess electricity and use it at night, during cloudy days, or when the sun isn't shining.   How solar power batteries work   Solar power batteries are a great way to store solar energy. They work by converting sunlight into electricity. This electricity can then be used to power things like lights or electronics. Solar power batteries can be used in a number of ways. They can be used to store energy when there is not enough sunlight. They can also be used to power devices when there is too much sunlight.   Best Solar Power Batteries   Looking for the best solar power batteries on the market? You ’ ve come to the right place! In this article, we will discuss some of the top solar power batteries on the market today. So, whether you are looking for a backup battery or an investment, read ...

Six Ways To Make Your Home More Energy-Efficient

  Home energy is a constant battle, and with the increasing cost of living, it can sometimes be hard to find ways to conserve. Take a look at these six tips for getting your home more efficient, including how to lower your energy bills and gain some peace-of-mind that you're doing your part.   Types of batteries   Batteries are needed for solar panels, windmills, and other types of renewable energy. Batteries can be found in three different materials: lead-acid, nickel-cadmium, and lithium ion. Lead-acid is the most common type of battery used today because it is cheap and easy to manage. The problem with lead-acid batteries is they produce hydrogen gas when they are discharged which can be explosive if mixed with other chemicals or gases. Nickel-cadmium is an alternative and safer to use because the gas produced is only hydrogen not dangerous chemicals like the spark from a welding torch. Lithium ion batteries are expensive but considered the safest type to use because t...
