EL5000BOily flux for lead-acid battery

I. Product Features
All organic active ingredients.  It is suitable for casting and welding electrode groups in lead-acid batteries such as medium and small density lead-acid batteries and electric vehicles, and can replace TBS N0.7 flux.  The voltage of the storage battery product produced by using the flux keeps stable and does not drop during use, and the consistency is good.
Second, product advantages
● Excellent activity, quick reaction with lead compounds such as lead oxide and lead carbonate, and strong activation capability on the surface of lead and its alloy;
● Improve welding quality and avoid chipping and false welding;
● Minimize the contact resistance of welding parts and improve the service life and performance of lead-acid batteries.  Especially for large current starting performance.
III. Scope of Application
Suitable for lead antimony, lead calcium and lead multi-element alloy plate grid electrode plate group welding.

V. methods of use
After polishing the lug, the flux is coated on the lug and then immersed in the lead furnace for a period of time depending on the temperature of the lead furnace.  During coating, only the soldering flux needs to be applied to the position to be welded, and no soldering flux is allowed to be applied to the non-immersed position.
Vi. matters needing attention
In the process of dipping flux, dip as little as possible to ensure that the electrode lug is coated with flux.
