First of all: in terms of technology, the continuous combination with the internationally compared DC inverter technology has finally realized the double-pulse welding, which is actually what we often say as continuous welding and pre-welding. Pre-welding can effectively remove the oxide layer, directly eliminate impurities and reduce sparks; Continuous welding ensures the beauty and firmness of the solder joint to a great extent, and there will be no blackening phenomenon. The solder joint is very uniform in size, and there will be no burr, mainly because it will not affect the appearance.

Secondly, under the control of microcomputer, the microcomputer inside the welding machine can scan the input voltage for a long time and at high speed. When the power supply fluctuates, it can calculate the compensation data and effectively change the welding ability, so as to ensure that the welding will not produce virtual welding or fire explosion due to voltage fluctuation, effectively ensuring the welding effect, mainly because the welding spark is relatively small and the impact on the battery is very small.

Later: the output of current is very stable, because the automatic spot welding machine of filament lamp is controlled by single chip microcomputer, and the current is very detailed in adjustment, which effectively ensures the stability of current output. Moreover, the welding is very unrestricted in the control of discharge time, and it can be welded continuously for at least 200 times per minute, and the welding effect is very consistent.
