— usually, arc welding in a shielding gas environment (MIG / MAG or TIG) is implied, carried out in the so-called pulsed mode.With this format of operation, the main welding current, which is relatively low, is supplemented by high-power pulses (7-10 times higher than the background current), which follow at a frequency of several tens per second. There are also various modifications of the pulse mode, with more complex current control; however, the original principle remains the same. Anyway, the advantages of pulsed welding are the uniformity of both the arc itself and the resulting seam, as well as an improvement in the overall quality of the joint: pulses help to mix the metal in the weld pool and eliminate pores, oxides and other defects. The disadvantage of this function is traditional — an increase in the cost of welding machines.
