Q:What is the reason for the flashing of the small LED spherical lamp?

Why would the poor contact soon after and bright: breakpoint near, due to thermal expansion and contraction because of why cause this situation: usually the reason for LED driving power supply circuit is too simple, another point is the factory that the burn time is too short.

Q:Can aluminum wire be used as welding rod for ws250 welding machine?

The content of impurities in common aluminum wire is higher, and the composition of welding wire and chemical elements can not meet the requirement of aluminum welding wire. Can not replace the aluminum welding wire for welding use.

Q:What can drum up Water Leakage glue

L, better solder it2, see how big hole, if not very easy to use aluminum wire, solder wire into the hole, with hammer flat.

Q:LV how to solder, seek expert advice, please everybody

Loading wire to welderThere is a knack for correctly loading aluminum wire (also applicable to steel wire), which is very important for loading aluminum welding wires and avoiding welding failures. Hold the wire shaft safely with one hand to make sure it won't let loose. Once you open the cellophane wrapper, hold the loose end of the wire with the other hand before you put it into the drive wheel. Inexperienced people usually fail to grip the loose end and cause the entire bundle of wires to start loosening. If this happens, it will not be remedied and welding operations will be greatly affected - you will have to buy another bundle of wire.

Q:Common causes and treatment of LED light flashing

This is the bad contact LED lamp gold or aluminum wire, usually, a welding wire connecting wire, arc welding off, if the two did not fill ball there may be two welding welding.

Q:Why use a sound line aluminum wire, another copper clad aluminum wire?

That's not aluminumTinned copper wireIf it's aluminum, it breaks off a couple of times

Q:There is aluminium on copper, take off caustic soda, can copper why become red?

Aluminum and alumina film easily reacts with oxygen to form dense, the sandpaper polished aluminum wire surface in order to remove the oxide film on the surface of aluminum

Q:With a broken rod can pine, or drill drilling with curved hair?

May take. The best drilling rod or broken tape and rope protection on thick aluminum wire with large camber after bending, if several times with dry soil, take good.

Q:What material (iron plate? Aluminium plate? Aluminium plate? Plastic board? Stainless steel plate? Can prevent the radiation of routers and light cats?

1, any metal plate can prevent electromagnetic radiation, and even the brick wall and other non conductive objects can reduce the degree of radiation.2, routers and light cats are not radiation ah;

Q:Why can't iron solder weld aluminum wire?

Copper oxide, aluminum oxide, iron oxide and so on are not easily used in soldering welding. That's why welding flux is needed.
