NBC-270~630 IGBT Inverter Welder with Overheat Protection Dual Welding Processes and Digital Current Display

Our NBC series GMAW welding machine incorporates advanced IGBT inverter technology, supporting dual welding processes: CO2 gas shielded welding and MMA stick arc welding. Equipped with an exclusive automatic wire melting ball function, this energy-saving, eco-friendly, and lightweight multi-process welder is an ideal equipment choice for small and medium welding workshops.

• Full Safety Protection System: Built-in overheating, overvoltage, and undervoltage auto-protection to prevent machine burnout from abnormal power conditions and overheating.
• High-efficiency Soft Switch Inverter Technology: Low power consumption with high working efficiency, providing significant electricity savings for long-time industrial welding operations.
• Digital Current & Voltage Display: Preset parameter preview plus real-time data showing during welding operation, enabling easy parameter adjustment for welders.
• Optimized Short-circuit Waveform Control: Stable welding arc with minimal spatter and smooth molten pool to reduce post-weld polishing work.
• Adjustable Arc Hardness: Arc characteristics adjustable from soft to hard mode, compatible with carbon steel, stainless steel, and aluminum alloy welding demands.
• Dual-purpose Welding & Gouging Function: Functions as both a welding machine and carbon arc gouger for weld root cleaning of all metal workpieces.
• Dustproof Isolated Air Duct Design: Power unit separated from air duct, effectively avoiding dust damage to internal circuits and extending equipment lifespan.

The internal power components are separated from the air duct structure to prevent dust erosion, greatly improving whole machine circuit stability and ensuring long service life. This design enhances reliability in demanding industrial environments.
