[0002] Electric welders use a high-temperature arc generated by a momentary short circuit between the positive and negative electrodes to melt the solder on the electrode and the material being welded, thereby bonding the two objects. Their structure is quite simple: a high-power transformer. Electric welders are generally categorized by the type of power supply: AC and DC. They utilize the principle of inductance, which produces a significant voltage change when connected and disconnected. The high-voltage arc generated by the momentary short circuit between the positive and negative electrodes melts the solder on the electrode, bonding the atoms together.
