2) Whether the positioning block is firm or not, and whether the positioning surface is worn is generally not more than 0.3mm.

3) Whether the pressure pliers can be reliably pressed and the head wear is serious. If the head area is too small and the workpiece is pressed out of the pit, it must be ground or replaced.

4) Whether the bolts of the connecting parts are tightened securely or not, and whether or not the solder joints are fixed at the spot welding are cracked.

5) Check whether the chute positioning is reliable and whether it moves freely.
