Key Features
- Inverter gas-shielded output: stable arc, low spatter and good bead formation
- Supports both CO2 and mixed shielding gas schemes
- Synergic single-knob adjustment for fast setup
- Stable wire feeding, tolerant of long cable runs and remote work
- Complete over-temperature, over-voltage and under-voltage protection
- Suited to all-position welding and continuous production
- 500 A output covering efficient welding of medium and thick plate
- Compatible with a water-cooled torch for high-duty continuous operation
Typical Applications
- Medium-heavy steel structures and heavy members
- Construction and mining equipment manufacturing
- Ship panels and offshore engineering
- High-volume multi-pass welding
Selection & Setup Notes
500 A targets medium-heavy plate and multi-pass work; pair it with a water-cooled gun for continuous duty. If your work is mostly thin sheet, the NBM-350D single-pulse controls spatter and distortion better.
