摘要
在对大多数逆变焊机的电网输入电路分析的基础上，对电网输入电流和焊机的功率因数进行理论分析和试验研究，提出了改善功率因数的几种方法。
The power input current and the ARG-welding machine power factor are analyzed in theory and tested by experiment in this paper,based on the analysis of the input circuit of the ARC-welding machine.It also develops several improving methods.
