With adjustable eccentric pressure work piece applied on this welder, welding process is artificially controlled with proper current and upsetforce.
该系列对焊机采用可调的偏芯轮压紧工件的方式，选择合适的电流档位和顶锻力，人控焊接时间完成焊接过程。

This series use screws to compress the work pieces. The welding process is finished under the reasonable current gear and upsetforce in the man-controlled time.
该系列对焊机采用螺杆压紧工件，选择合适的电流档位和顶锻力，人控焊接时间完成焊接过程。
