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.

What is the term tw refers to in welding?
TW = thermite welding, a welding process that requires no external source of heat or current.
Is current source available in any circuit?
The question is vague.A current source is the short form of constant current source.A voltage source, on the other hand, is the short form of constant voltage source.That being so, then no, a current source is not available in any circuit.
One source of constant electric current is a?
Alah
Do you agree or disagree with your lab partner who says a battery provides not a source of constant current but a source of constant voltage?
agree
Why you use constant current source?
What follows below is not a full description. Full descriptions are in chapters of books about electronic power supplies.A constant current source is an electronic device which acts as a source of power whereby, however the load resistance changes - within a certain fixed range - the device is designed to monitor the output current drawn from it and will change its output voltage to keep the output current constant within a certain fixed range.Another answerA constant current source will provide constant current with a load if the load changes the volts will change to compensate for the constant current flowing. Which is just opposite to a constant voltage source whereby a load change will change the current but not the voltage. And that how it works.

What is the output impedance of a constant voltage source and constant current source?
The output impedance is z= V/I, the ratio of the constant voltage and the constant current source.
What ismean by current source?
A current source produces a constant current no matter the variation in voltage.
Is a battery provides not a source of constant current or a source of constant voltage?
Batteries will provide a source of constant voltage. A battery also can be used to produce an electrical current immediately upon a necessary connection.

What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
What is an example of electric current?
Here are a couple. Assuming everything is "normal" here, if you drop a bagel in the toaster and turn it on by pushing the lever down, the AC current the toaster uses (draws) will stabilize after a few seconds and stay constant. If you turn on your car's headlights, each lamp will draw a constant current from the DC source after a few seconds of "warm up" time. Those are examples of constant electric current.
Highly inductive load as a constant current source?
An inductor is a device that resists a change in current. The equation is di/dt = v/L. This means that inductors are current sources, and given a sufficiently large inductor, in comparision to the circuit, it is a constant current source.
Are dry cells a source of constant direct current voltage?
Yes.
