Fire-resistant door spraying machine eccentricity main cause

Spot welding machine weld bead eccentricity is mainly caused by misaligned electrodes or poor contact surfaces between the two electrode faces. Custom AB glue machine, improvement measures:

1) The upper and lower electrodes of the spot welder should be made into flat electrodes of the same diameter and in a fixed type. Generally, the lower electrode should not be movable.Spherical electrode.

2) To ensure evenness and flatness, place a layer of carbon paper between the upper and lower electrodes on a stiff cardboard. Apply slight pressure and slowly rotate the cardboard.A clear electrode shape can be obtained, thereby determining the concentricity and flatness of the spot welding machine electrode.
