Start Settings
The Start Settings should be set up after the process
setup has been completed. The start settings screen –
see
FIGURE 24 - Start Settings Screen –
allows the
user to adjust the start settings specific to the pro-
gram which affect how the system acts when the weld
starts. The start settings take effect as soon as the
Start/Stop button is pressed to initiate the weld. Refer
to
page B-21
to see a full timing diagram.
The settings that can be changed in this screen are:
Preflow
The amount of time (sec) that gas flows before welding
begins to ensure adequate gas coverage for the weld
preventing starting porosity.
Upslope
This is the amount of time (sec) it takes for the system
to ramp up from start settings to welding parameters.
RunIn WFS
Determines the WFS prior to establishing an arc will
ramp up to welding WFS during upslope.
RunIn Volts
The voltage or trim setting at which the system begins
to weld. Once established, it will ramp to welding volt-
age during upslope.
Motion Delay
This determines how long the system will wait before
beginning to travel and oscillate.
End Settings
The end settings screen – see
FIGURE 25 - End
Settings Screen
–
allows the user to adjust the end
settings specific to the program, which affect how the
system will behave at the end of the weld. End set-
tings take effect as soon as the Start / Stop button is
pressed to stop the weld. (Refer to
page
B-21
to see
a full GMAW/FCAW timing diagram.) The settings that
can be changed in this screen are:
Crater WFS
- The wire feed speed during crater
Crater Volts/Trim -
The amount of voltage/trim during
crater
Crater Time
- The duration of crater
Burnback -
The time the arc is maintained after the
wire stops at the end of a crater.
Downslope
- The time to ramp from welding parame-
ters to crater parameters
Postflow
- How long the gas continues to flow after
the weld to provide shielding
Both the Start and End Settings screens provide ac-
cess to the Advanced screen to allow advanced values
to be set for start and end of weld.
