Lincoln Electric IM649 Wave Designer - Manual (Page 28)

6. Status Bar The status bar provides a scrolled listing of recent
Wave Designer program
operations, error conditions, etc., and three operational status indicators. The adaptive
indicator is also a button that toggles between the Adaptive and Non-Adaptive mode.
7. Graphical Display Area The graphical display provides refreshed displays of the selected
waveforms from the output of the connected power source. The power source sampling rate
is 10kHz, unless the Condense option is selected.
4.1.2 OTHER ARC SCOPE OPTIONS
Live Update: The Live Update option is normally on (checked) to display changing output data
during the weld application. To maintain an existing display for study while welding, turn the Live
Update option off.
Condense: The Condense option is normally off (not checked). When turned on, the Condense
option forces the welding machine to sample data only during weld state transitions. This extends
the length (time) of the sample stored in the welding machine buffer and records only what
happens during weld state transitions.
Browse: The Browse left/right options allow you to display the contents of the welding machine
storage buffer following a weld application. The buffer stores the last 300 milliseconds of
sampling data when the Condense option is off. (Longer samples are stored when the Condense
option is on.)
Pause/Let Go: The Pause option allows you to freeze an ArcScope display while the welding
application is running. The Let Go option disables the Pause function.
Configure: Use the Scope Configuration window to select the power source measurements for
the graphical display area.
Centerline: Select the Centerline option to place a
gray centerline in each of the displays.
Available measurement/display options include:
Volt: average power source output voltage
Amp: average arc current
GSF: (Global Scale Factor) correction factor
forcing the weld application to the desired
arc length
State: the state progression of the welding
application (ramp-up, peak, tailout, etc.)
Watt: instantaneous power output
dv/dt: rate of voltage change per unit time
calculated at a 10 kHz sampling rate
dI/dt: rate of amperage change per unit time @
10 kHz
dp/dt: rate of power change per unit time @ 10
kHz
ohm: arc impedance
dr/dt: rate of resistance change per unit time @ 10 kHz
Reverse Polarity State: For machines with an AC welding option, Reverse Polarity State
selects the State (0 to 19) for electrode negative.
Waveform Start State: Specifies which Power Wave state (0 to 19) is used to calculate the
actual frequency displayed on the bottom left side of the ArcScope window.
Wave Designer
counts the elapsed time between the start of this state to calculate the frequency. The Waveform
Start State is set to 8 by default. Call Lincoln Electric for more details.
