WebDetermine the secondary voltage if the secondary circuit is open and the primary voltage is 120 V. Medium. Open in App. Solution. Verified by Toppr. First we use the fact that the ratio of the voltage on the secondary and on the primary will be the same as the ratio of the number of turns of both coils, WebJul 11, 2024 · At this temperature, mechanical pressure for melting is not required. Both AC and DC can be used in the arc welding. Usually, 70 – 100 V on AC supply and 50 – 60 V on DC system is sufficient to strike the arc in the air gap between the electrodes. Once the arc is struck, 20 – 40 V is only required to maintain it.
