The features of manual downhill welding, semiautomaticwelding, automatic welding and other welding technologies like butt flash welding and laser beam welding (LEW) and so on are analyzed.
The controlling system has many work patterns, such as manual, semiautomatic, and automatic, and can compensate for the effect of voltage fluctuation to welding current.
控制系统具有手动、半自动、全自动等工作方式,可自动补偿网压波动对焊接电流的影响。
