Key Features of the NBE Series of Inverter AC MIG Welding Machine
-
Smart DSP Digital Control
-
30 Programmable Memory Channels—Save your best welding parameters (current, voltage, pulse settings) for instant recall.
-
Function Lock Key—Lock settings to prevent accidental changes, ensuring weld consistency across shifts.
-
-
AC Pulse & Dual Pulse Mastery
-
Crisp Fish-Scale Patterns: Dual-pulse mode creates stunning, uniform welds on aluminum (Al, AlSi, AlMg) with low heat input—perfect for thin sheets or decorative work.
-
Strong-Weak Pulse Switching: Hear the arc “sing” with precise control over penetration and aesthetics.
-
-
Industrial Toughness
-
100% Duty Cycle: Weld nonstop at max current (630A for NBE-630 model)—no overheating, no downtime!
-
Water-Cooled or Air-Cooled Torch: Choose cooling based on your workload. Water-cooling handles marathon sessions; air-cooling suits lighter jobs.
-
-
Robot Integration Ready
-
Built-In Robot Interfaces: Pair the NBE Series of Inverter AC MIG Welding Machine with automation systems for factory-floor efficiency.

Advantages:
A.In bottom welding, the backside of welding seam is also good, the defects can be avoided
B.Penetration about 20% bigger than the general DC MIG/MAG welding in the big current welding (300A)
C.Welding speed is 15% higher than the general MIG/MAG welding
D.In fillet welding, welding meat is flat and smooth, no bulge
- Iron water flows smoothly and is easy to control in covering welding
- Suitable for sold/flux-cored wire
