讨论了在手工电弧焊焊钳上施加智能控制的可能性。手工电弧焊中决定焊接质量的一个重要因素是弧长的随机波动，在焊钳上加上一个附加的调节运动原则上可以消除或减少这种波动。本文主要探讨了该系统的原理并进行了机械和电路的初步设计。
Discusses the possibility of applying intelligent control on a hand-held arc welding torch. An important factor in determining the weld quality in manual arc welding is the random fluctuation of the arc length. The addition of an additional adjustment movement to the welding tongs in principle eliminates or reduces this fluctuation. This paper mainly discusses the principle of the system and the preliminary design of the mechanical and electrical circuits.
