Power supplies can supply AC or DC current.

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.
Alternating Current "AC" & Direct Current "DC"
Coal, oil, and natural gas
There are two types of current AC current DCcurrent
Alternating current and Direct current
To contain and To deliver
Capacitive loads have a leading power factor. Current leads voltage when there is capacitive reactance. (The opposite is inductive, which is lagging.)
If the question is about electric current, then types of currents are alternating current (AC) and direct current (DC).
There is pure resistance, inductive reactance, and capacitive reactance.
Electric current from a generating plant is a alternating current transmitted at high voltages, but usually used at low voltages.
