Welding current. One of the important reasons that affect welding quality is the welding current. If the current is too high, it is easy to cause overheating or deformation of the welding part, which can damage the welding parts. If the current is too low, the welded part will not be able to fully melt, resulting in incomplete welding; Different types of welding components require different current values, and practical judgments need to be made based on the material and thickness of the workpiece.
Welding voltage. During the welding process, voltage and current cooperate with each other. If the voltage is too low, it can lead to poor welding effect and instability; If the voltage is too high, it is easy to damage the workpiece and generate splashes. Experienced personnel will pay special attention to the coordination and adjustment of voltage and current during the welding process.
