1) Electrode Shape: Confirm the usability of the electrode shape. Ensure the electrodes are cleaned after a period of use.

2)Surface Cleanliness: Use a file or sandpaper to clean the electrode surface after a period of use.

3) Cooled Water Temperature: Maintain consistency in the cooled water's temperature. An increase in electrode temperature will decrease its durability.

The above factors significantly impact welding quality and appearance.
