DN功能及特点：
1、加压方式采用脚踏杆，结构简单。
2、脚踏杆控制电路，不踩下时主机则不通电，能节约电能。采用定时控制，焊接时即使工件仍被压住，但电流却能按时自动切断，减少人为因素，操作更加容易，焊点质量更稳定。
3、时间定时采用电子控制器调节，调定范围0.02~2秒（通常工件焊接所需时间在0.5秒内）精确地重复选择。

DN series foot-operated spot welder
Functions & Features:
1.A simple structure, with a foot lever for pressurizing.
2.Control circuit of foot lever; the mainframe is power-off when the foot lever is released, which is good for energy saving. Timing control; even if the work piece is pressed during welding, the current can be cut off automatically on schedule. This helps reduce impact of human factors and realize easier operations and stable of welding spots.
3.An electronic controller is used for timing. Accurate adjustment: 0.02-2 seconds(usually the welding time required is less than 0.5s)
