Relationship between the voltage and current for different process in CV type power source is as under

GMAW:

V = I * 0.05 + 14

FCAW:

V = I * 0.05 + 18

Note:

Some power source have both CC and CV characteristics. The explanation given above is general and

the capability of the machines depends on the model number of the machine purchased by you.
