1 Answer

Answer :

Special features of welding transformer:

i) It is a step down transformer that reduces the source voltage to a voltage desired according to the demands of the welding process.

ii) Having large primary turns and less secondary turns.

iii) The secondary current is quite high.

iv) The secondary has several taps for adjusting the secondary voltage to control the welding current.

v) The transformer is normally large in size compared to other step down transformers as the windings are of a much larger gauge.

vi) Common ratings:

i) Primary voltage – 230 V, 415 V

ii) Secondary voltage – 40 to 60 V

iii) Secondary current – 200 to 600 A
