    smaw and tig(gtaw) are using CC source. because these both types using manual wire feeding. so welder can not able to maintain constant arc length. change in arc length will change voltage. so it needs power supply which should not affected by this arc length = voltage changes. that's why CC type is used for these process. in CC type source change in voltage will not change current much.
