AC welding machines

Variable

— alternating current does not have a specific polarity, the “plus” and “minus” with such a connection constantly change places, and it is physically impossible to reverse the polarity. On the other hand, AC welding is considered less accurate than DC welding, this option increases the amount of spatter and reduces the overall quality of the work. However in high-end inverters, this drawback can be almost invisible — nevertheless, there is one more thing: only special electrodes, originally designed for this power format, are suitable for alternating current. As a result of all this, simple work with MMA arc welding remains the main area of \u200b\u200bapplication for alternating current.
