一种新型扩展作用范围的推挽式送丝系统XR—15和XR—30是以铝和其它软合金作为焊丝,适用于气体保护金属极电弧焊。这种新装置可送进硬焊丝,也可送进药芯焊丝。该装置是采用美国威斯康星州米勒电焊机制造公司的高技术设计而成的,是一个用电子仪器控制的、固态、恒速系统。该系统的特点是重量轻、良好平衡的手枪式握把以永久性磁铁24V直流电机驱动推动着焊枪。焊枪与一台115V交流转矩
A new extended range of push-pull wire feed systems XR-15 and XR-30 are aluminum and other soft alloys used as welding wire for gas metal arc welding. This new device can be fed into the hard wire, can also be sent to the flux cored wire. The device is based on the high-tech design of Miller Weld Manufacturing Company in Wisconsin, USA. It is a solid-state, constant-speed system controlled by electronic instruments. The system features a lightweight, well-balanced pistol grip driven by a permanent magnet 24V DC motor that drives the torch. Torch with a 115V AC torque
