Welders 400 V

3 phase (400 V)

— a three-phase 400 V circuit is used to power industrial equipment and is practically never found outside workshops and other specialized premises. Accordingly, welders for such a mains usually have an appropriate purpose, high power and productivity. It makes no sense to purchase such a device for simple household work — not only because of the excess power, but also because of the difficulties in connecting. But for professional tasks, such models can be very useful.
