NBM-350D Single-Pulse MIG / MAG Welder

CO2 / MIG / MAG Welder

NBM-350D single-pulse MIG / MAG welding machine with digital inverter control. Rated at 350 A, it provides a stable pulsed arc with low heat input, and is particularly suited to thin sheet and heat-sensitive materials. Single-pulse waveform control keeps heat input low and distortion small. The arc is stable, spatter is minimal and the bead appearance is clean. Synergic adjustment makes parameter storage and recall convenient, and protection against over-voltage, over-temperature and under-voltage is comprehensive. Applications Carbon steel, stainless steel, aluminium and aluminium alloys in thin and medium plate. Widely used in sheet-metal fabrication, automotive, rolling stock and kitchenware manufacturing.

Key Features

  • Inverter gas-shielded output: stable arc, low spatter and clean bead formation
  • Supports both CO2 and mixed shielding gas schemes
  • Stable wire feeding, tolerant of long cable runs and remote work
  • Complete over-temperature, over-voltage and under-voltage protection
  • Single-pulse control: one droplet per pulse, reducing spatter by more than 80%
  • Precisely controllable heat input: thin sheet resists burn-through and distortion
  • Easier pool control in vertical and overhead positions, consistent all-position appearance
  • Synergic adjustment with convenient parameter storage and recall

Typical Applications

  • Thin sheet assemblies and panel work
  • Stainless products and food/pharmaceutical equipment
  • Vehicle modification and precision structures
  • Batch production sensitive to post-weld cleaning cost

Selection & Setup Notes

The value of a single-pulse machine is straightforward: it removes post-weld grinding. Spatter drops by over 80% and thin sheet resists burn-through and distortion. If bead appearance matters too (the rippled finish), see the NBM-350DP double-pulse.

Frequently Asked Questions

How do I set pulse parameters?

Choose mean current for material and thickness, then set peak, background and frequency while watching droplet transfer and spatter. Calibrate on a test plate first.

Is pulse welding slower?

Lower heat input usually allows higher travel speed; on thin sheet and all-position work, overall productivity is often better than short-circuit transfer.

Is it suitable for aluminium?

Yes, but for thin aluminium sheet the double-pulse model is preferable for both the rippled appearance and heat control.
