The electrode rod is an important part of the welding machine. Discharge welding is completed by the electrode rod. However, many people do not understand that the electrode rod is a consumable and needs to be replaced when it reaches a certain life span. Although the metal itself is hard and will not be worn by external forces, it needs to withstand high temperature discharge for a long time. At the beginning of the discharge, it will inevitably wear out slowly.

During the discharge process, the glass ions of the fiber itself diffuse and adsorb to the tip of the electrode rod due to high energy and heat, forming non-conductive insulating impurities. After using the electrode for a period of time These impurities can be observed on the rod with the naked eye.

The generation of the insulating film will cause the arc to avoid it and discharge, so the original loss from the top may be transformed from the rear. If this happens, the wear rate of the electrode tip will increase and it will become very irregular.

It is also very important to choose the original electrode rods. The fake and inferior electrode rods have materials that cannot withstand high temperatures and are of different sizes. In this way, not only the life of the electrode rod itself will be very short, but also the discharge voltage may be unstable due to In this case, the power devices inside the fusion splicer will be burdened or even damaged.

(6) After the electrode replacement is completed, execute [Reset the number of discharges].
