Welding Machine Ultra box UT-MMA-350


Ultra box Welding Machine is made with the latest IGBT third-generation technology.

It has high voltage transistor with electronic efficiency converter which is designed for home or semi-professional use.

It has Hot Start, Arc Force and Anti Stick functions.

The Hot Start function allows us to increase the current at start-up for faster use of the machine. Arc Force is an automated function for stabilizing

performance, regardless of the time of use of the machine. The Anti Stick function prevents the welding of electrodes to the welding materials.
