6 CONTROL PANEL
6.4.2

RobustFeed AVS with CC Power Sources

1) Select the weld current/arc voltage needed for the wire type and diameter to be welded, see
section "Weld data table" in this chapter.
2) Set the power supply current with the knob for setting the current on the front panel of the power
source.
3) Set the wire feed speed value taken from the weld data table using the knob for setting the wire
feed speed on the wire feeder.
4) Strike an arc and adjust it to the desired wire speed with the knob for setting the wire feed speed.
6.4.3

RobustFeed AVS with CV power sources

1) Select the arc voltage/weld current needed for the wire type and diameter to be welded, see
section "Weld data table" in this chapter.
2) Set the power supply voltage with the knob for setting the voltage on the power source or use the
optional remote voltage control in the wire feeder.
3) Read the wire feed speed at the top of the column in the "Weld data table" for the chosen wire
type, diameter, and arc voltage/weld current.
4) Use the "Weld data table" to determine the position of the knob for setting the wire feed speed on
the wire feeder.
5) Strike an arc and adjust the arc length as needed with the knob for setting the wire feed speed.
NOTE!
It is NOT RECOMMENDED to use the CV switch setting when using a CC power source.
Extreme wire feed speed sensitivity exists that makes it difficult to set a stable welding
condition. The arc stability is very dependent on maintaining constant "Tip To Work" (TTW)
distance which is almost impossible to control when welding manually. CV setting is only
recommended for use with CV power sources.
NOTE!
On many CV power sources, the actual welding arc voltage is less than the "Open Circuit
Voltage" (OCV) set on the power source front panel. Therefore, an extra 3 to 6 volts may
be added to the power source front panel setting to achieve the actual arc voltage needed
or shown in the tables.

Shutdown

1) Release the torch trigger switch to break the arc.
2) When leaving the equipment unattended, always turn off and disconnect all power to the
equipment and turn off the shielding gas supply at the source.
