General Mig/mag (Nbc-250m,nbc-350m,nbc-500m)

Features:-
1. Use phase shift full-bridge inverter main circuit and the whole welding machine has a high reliability.
2. The dual wave control circuit of superior voltage and current, the small welding spatter and beautiful welding forming.
3. Simple operation; weld with the long control cable around the narrow and high areas.
4. The numeration table can presets current and voltage; humanization design without cumbersome external welding specifications.
5. The special AFTT with removing ball circuit; there is no remained ball at the terminal after welding.
6. Configuring the wire feeder with straightener and the wire feed function is superior; the arc is still stable when the welding torch bends excessively.
