Common problems with manual operation of photovoltaic junction boxes

The straightening operation of the busbar before installation caused damage to the busbar.

The "Lineman's pliers" is often used manually to clamp and straighten the bus bar, which may damage the bus bar and affect its strength after welding. However, such defects cannot be found in subsequent inspection and will inevitably cause quality problems.

The installed busbar is not flattened in place. Manual installation involves manually pressing the busbar, which may not be in place and directly affect the welding quality of the next busbar welding process.
