Welding current (A), estimated duty cycle during operation (Φ), no-load voltage on the output side (V), operating efficiency (ξ)
By default: A = 1,500 A, Φ = approx. 20%, V = 110 V → Primary input Po = 1,500 × 110 = 105 (kVA)
Therefore, a power transformer with a capacity of 110 kVA or more must be provided.
