Transformer AC SMAW (STICK) Welding Machine AC-320 / AC-420 / AC-520
MMA SERIES
- Manually operated by a single person.
- Made up of a moving-iron type arc welding transformer.
- Uses trapezoid magnetic core as the magnetism shunt, with the result of a wider regulation range for the current.
- High grade insulation material
- Quick radiation, high effiency and longer operating life.
- Compact Structure, low noise and convenient remotion.
