KOBEWEL KMD-502 GMAW/MIG/MAG Welding Machine 40-500A, with Separate Wire Feeder (Made in Japan)

HIGHLIGHTS:

The Kobewel KMD-502 GMAW/MIG/MAG Welding Machine is a heavy-duty industrial welding system built for sustained, high-output MIG/MAG welding applications. Featuring a wide welding range of 40–500A and a robust 390A welding current at 100% duty cycle, it delivers the power and reliability required for continuous industrial welding work without performance compromise.

The KMD-502 is configured with a separate wire feeder unit — distinct from the main power source housing, with its own dedicated dimensions (550 x 242 x 410mm) and weight (21kg), separate from the main machine (950 x 390 x 750mm, 150kg). This configuration is characteristic of industrial-grade MIG/MAG welding systems, allowing the wire feeder component to be positioned independently from the bulkier main power source for more flexible job site setup.

With a wire feed rate of 0.5–20 m/min, the KMD-502 handles both steel wire (0.8–2.4mm) and aluminum wire (0.9–2.4mm), making it suitable for a broad range of metal welding applications. Running on a 3-phase 380V supply with a maximum power consumption of 23kVA and a power factor of 0.96, the machine is engineered for efficient power delivery in demanding industrial environments. Insulation Class H and Type F cooling support sustained operation under heavy continuous use, while noise emission is kept to under 75 dB(A).
