- High welding efficiency: It can quickly achieve the connection of metals. Especially for some thick plates, it can complete the welding in a relatively short time, improving work efficiency.
- Good welding quality: It can precisely control parameters such as welding current, voltage, and time to ensure the strength and sealing performance of the welded joint. The welding quality is stable and reliable.
- Low cost: Compared with some other connection processes, such as riveting and bolt connection, the equipment cost and operation cost of the electric welding machine are relatively low, and a large amount of auxiliary materials are not required during the welding process.
- High flexibility: It has a small volume, is easy to move, and can be used in different workplaces. It is suitable for welding operations of various scales and can play a role in both large-scale industrial production and small-scale maintenance and processing.
