该文依据理论分析和实验证明用弧焊机的空载电流指标来规定弧焊机节能指标,有可能造成能源和材料的浪费。并与实现寿命经济效益最佳焊机的目标相矛盾。故建议取消弧焊机标准中关于空载电流I_0<10％I_(1H)的规定,编撰符合国情,维护国家根本利益的弧焊标准。
Based on the theoretical analysis and experiments, this paper proves that using the no-load current index of arc welding machine to stipulate the energy-saving index of arc welding machine may cause the waste of energy and material. And contradicts the goal of the best welding machine to achieve economic benefits of life. Therefore, it is recommended to abolish the standard of arc welding machine about the no-load current I_0 <10% I_ (1H), and to compile arc welding standards that are in line with the national conditions and safeguarding the fundamental interests of the country.
