The PATON™ BPI digital wire‐feeding machine is designed for operation as a part of an external welding source in the semiautomatic metal inert/active gas welding (MIG/MAG) mode. In this case, the source feeds the power welding current, and the feed unit provides a stable supply of solid or flux-cored wire to the weld pool. The wire‐feeding machine has its own inverter power supply for the motor, the protective gas supply valve, and the control circuit. The distinctive feature of PATON™ semi‐automatic machines is very robust, high‐quality, and structurally sound wire feeding mechanism, as well as availability of the KZ‐2 socket of world standard EURO type, which allows user changing torches at his/her own discretion. The protective gas supply valve is built into the unit.
