A constant voltage (CV) power source is recommended for flux-cored arc welding
(FCAW) and gas metal arc welding (GMAW) to obtain c ode quality results.
However, this wire feeder may also be used with a c onstant current (CC) power
source to obtain passable results for noncritical q uality applications.

On recommande une source de puissance à tension con stante (CV) pour le
soudage à l'arc avec électrode fourrée (FCAW) et le soudage à l'arc gaz métal
(GMAW) pour obtenir des résultats de grande qualité . Cependant, ce chargeur de
fil peut aussi être utilisé avec une source de puis sance à courant constant (CC)
pour obtenir des résultats acceptables pour des app lications de moindre qualité.

The serviceability of a product or structure utiliz-
ing the ACTIV8™ wire feeder is and must be the
sole responsibility of the builder/user. Many vari-
ables beyond the control of The Lincoln Electric
Company affect the results obtained in using the
ACTIV8™ wire feeder. These variables include,
but are not limited to, welding procedure, plate
chemistry and temperature, weldment design, fab-
rication methods and service requirements. The
available range of the ACTIV8™ wirefeeder may
not be suitable for all applications, and the
builder/user is and must be solely responsible for
welding settings.
CONSTANT CURRENT OPERATION
Setting Wire Feed Speed in CC mode
When Across the Arc models are operated with CC
power sources, the wire feed speed changes as the
arcvoltagechanges.Whenthearcvoltageincreases,
the wire feed speed will increase; and when the arc
voltagedecreases,thewirefeedspeedwilldecrease.
TopresetthewirefeedspeedonCCpowersources:
1.Set the Wire Feed Mode switch inside the
ACTIV8™ to"CC".
2.RefertotheFigureB.4graphtodetermineccset-
tingofthewirefeedspeedknob.Selectthehori-
zontal line representing the Desired Wire Feed
Speed.(SeeFigureB.4arrowfor375in/min.)
3.Select the diagonal line representing the Arc
Volts.(SeeFigureB.4for29volts.)
4.Determine the vertical line representing the CC
Wire Feed Speed setting where the above two
lines cross. (See Figure B.4 arrow line for 450.)
Set the ACTIV8™ wire feed speed knob to this
value.
