    As with the above, its a procedural thing. Procedure calls for CV, you use CV. Wires in CC will be pure spray, and will only work with a VS feeder. Penetration, and over all adhesion will be vary low. so while it looks pretty, the weld will fail on critical applications. On machines like the Lincoln 350 pro there is an innershield setting and Lincoln powerwave in STT mode. This uses a modified cc signal, with a background voltage. Miller has tried to copy this in thier Axcess and static Pippros. MASSIVE problems in the past.

    In otherwords, you have CV then use it.....

    Stick mode...is cc current only good for stick, with dual shield and some self shielded wire running ok, but if it is going to be xrayed, a welder caught running wire with a cc only machine welds will be failed.

    Wire mode....is cv ie constant voltage. Now there is settings for voltage sensing. This basically leaves the electrode hot all the time, thus the feeder box must have a contactor inside the machine to turn power on/off when the gun trigger is pressed.

    Wire mode through 14 pin plug....basically feeder ties into welder, the welder has a contactor inside, the feeder tells the welder current on, current off, normally you also can set voltage at the feeder, not as handy in the mud as there is another cord to trip on. However it is very nice when the feeder is in a hole, and the welder is 100ft away.
