NBM-350/500 Combined Double Pulse MIG Welders – Advanced Inverter Technology for Superior Aluminum Welding

Release time: 2026-06-05


NBM-350 Combined and NBM-500 Combined double pulse MIG welding machines, designed to deliver exceptional welding performance across carbon steel, stainless steel, copper, and especially aluminum and aluminum alloys. With advanced IGBT soft‑switching inverter technology and a fully digital control architecture, these new models set a new standard for stability, efficiency, and weld quality.

Precision Welding Process for Minimal Spatter & Perfect Beads
The NBM series combines a high‑stability PWM wire feeding circuit with closed‑loop arc self‑regulation, ensuring a consistently stable welding process – even under harsh shop floor conditions.

Short‑circuit transition welding produces dramatically reduced spatter.

Pulse welding achieves virtually spatter‑free operation, ideal for cosmetic or critical joints.

The double pulse process is especially effective for aluminum, providing fine droplet transfer and a smooth, ripple‑free bead appearance without extensive post‑weld cleaning.

Digital Integration & Smart Features
Both models feature a full digital structure that integrates the water tank, wire feeder, and power source into one compact unit (1040×580×1480 mm). This high‑integration design lowers machine failure rates and simplifies operation.

Welding process storage and recall – store optimized parameters for repeatable jobs.

Software upgradeable – supports special welding processes.

Human‑centric design – intuitive controls with a beautiful, generous appearance.

Rugged & Reliable in Harsh Environments
Key components are built with three‑proof protection (dust, moisture, and salt spray), allowing stable operation from –10°C to +40°C.
