Welding inverter Sturm 300A has a wide range of welding and works with electrodes with a thickness of 1.6 to 4 mm. The device is lightweight (3.26 kg) and convenient dimensions, while at the same time demonstrating high productivity with a duty cycle of 60%. The welding current range is 20 to 300 A. The accuracy of the current setting is controlled by a digital display. EXTRA POWER 20-300A mode – when this function is activated, the maximum value of the welding current increases, and the intelligent ventilation system turns on when the temperature of the elements exceeds 40 ° C and turns off if there is no activity for two minutes, thus preventing heat shocks inside the machine and reducing the amount dust inside the case.
