1. Electrical faults are the most common, including contactor burnout in the control cabinet, relay failure, and short circuits due to aging wiring. These can cause the equipment to fail to start, run unstablely, or stop abnormally.
2. Mechanical faults are mostly related to moving parts, such as jamming of welding fixtures and translation slides, abnormal noises, and inaccurate positioning. These are usually caused by dust accumulation on the guide rails, wear of transmission components, or deformation of the fixtures.
3. Welding quality problems manifest as weak welds, surface oxidation, slag spatter, and perforations. These are caused by improper welding parameter settings, unstable pressure, impurities in the material, or inadequate cleaning.
4. In addition, scratches are also a frequent fault, often caused by improper adjustment of the guide mechanism or extrusion rollers. It is necessary to check the die fit, roller height, and pressure.
