Unica MMA-291Ti

An excellent device, in six years of operation it has never turned off due to overheating. Even at an air temperature of +25, having melted 34 electrodes with four continuously in maximum mode, however, the holder and the mass became very hot. It was necessary to melt a shaft with a diameter of 60 mm and a length of 950 mm from the frame of a reversible plow. For some reason, these devices are afraid of the contact of the mass holder with the body of the device itself. The only downside is the length of the wires: the positive cable is 180 cm, the weight is about 150 cm, but there is enough power to add. I didn’t notice much of a difference between the MMA TIG mode when you work with an arc.
