Welding Power Source
The welding power source converts line voltage into a suitable low current and arc voltage to stabilize the arc. It ensures stable process control through a steep or flat characteristic.
Physical-Chemical Mechanism of Action
The welding power source transforms the mains voltage into a low current and working voltage suitable for the arc. This is done through special conversion and regulation of the voltage to achieve the desired temperature and flow profile in the welding area.
Metallurgical Relevance & Risks in Welding
An inaccurate power source can lead to instability in the arc process, causing irregular weld quality and possible cracks or distortion. A stable power source is crucial for high joint quality.
Workshop Practice & Action Instructions
The power source should be checked regularly to ensure it is correctly calibrated and operates stably. If there are issues with stability or the arc process, the power source may need to be readjusted or serviced.
