Welbee M350 MIG Inverter | Full

NEW Welding Power Supply

Welbee MIG Inverter

The Welbee M350 and Weblee M500 MIG inverters are designed for high quality welding in any situation. 

The M500 is the 500 amp standard welding power supply for high quality welding in any situation at 100% duty cycle.

Both the M350 and the M500 provide superior arc stability in the entire range of low-to-high welding currents and always delivers a beautiful weld bead end with less voltage fluctuation, even during high-speed welding.
