+100% duty cycle, especially suitable for working in bad conditions such as long-term using, high

temperature and large current when used in heavy industry (MZ1000);

+ High efficiency and energy saving, the main circuit power source will be cut automatically if arc striking fail

within 30 minutes;

+High efficiency, slow wire feeding speed, 100% arc striking;

+Digital display of current and voltage, easy operation;

+Two wire feeding mode: variable speed and constant speed;

+Two wire feeding mode: variable speed and constant speed;

+The machine will stop automatically when the wire contact with the work piece.

+PWM adjusts wire feed and tractor travel speed:little effect by input voltage and temperature;
