一、问题的提出及国内外现状减轻焊机重量及提高功率因数以节约能源的努力,在已成熟定型的BX、AX及ZXG三个主要系列的焊机中,潜力有限。从增大铁芯磁通密度(Bm)和铜线电流密度、
First, the issue put forward and the status quo at home and abroad to reduce the welder weight and improve the power factor to save energy efforts, has mature stereotypes BX, AX and ZXG three main series of welders, the potential is limited. From increasing the core flux density (Bm) and copper current density,
