1.INTRODUCTION
MIG/MAG 550A-RWS and MIG/MAG 550W-RWS are professional, easy-to-use, compact,
reliable, robust, economical and semi-automatic MIG/MAG welding machine with
excellent welding characteristics, offering the ability to weld all solid and cored wire
types. MIG/MAG 550-RWS, provides precise voltage adjustment with 4 coarse, 10 fine,
40 steps in total.
MIG / MAG 550 W-RWS gas metal welding machine has two main parts. The wire feeder
unit names NSK 4-C and welding power supply.
