What Are The Reasons Why The Spot Welder Makes Harsh Sounds During Welding?

During the welding process, the spot welder sometimes makes a harsh sound, which not only affects the operator's work experience, but may also indicate welding quality problems.

1. Welding current is too high

When the welding current is set too high, the molten metal will produce a violent arc effect, resulting in a sharp and harsh sound.

2. Insufficient electrode pressure

Too low electrode pressure will lead to poor contact between the workpiece and produce a jumping or unstable arc during welding, which will produce a harsh sound.

3.Poor surface condition of the workpiece

The presence of rust, oil or oxide layer on the surface of the workpiece will affect the conductivity and welding stability, resulting in abnormal sound during welding.

4. Poor contact of equipment

Poor contact of the electrode head, cable or terminal of the spot welder will cause current fluctuations and cause harsh noise during welding.

5. Improper welding parameter settings

If the welding time is too short or the frequency setting is inappropriate, the welding process may be unstable, resulting in harsh sounds.
