Auto Calibration Procedure

The auto calibration procedure is used to provide an automatic means of configuring the pull gun to operate with
the optimal setting of Gun Offset (P.7 in the user preference menu).
Before running the auto calibration procedure, make sure that the system is set up and ready for welding. P.24
must also be set for the correct pull gun type prior to running auto calibration.
To begin the auto calibration procedure, select P.50 from the user preferences menu. Press the "Begin" button to
start the calibration. Pull the gun trigger and hold it closed throughout the procedure. Wire will feed out of the gun
while the calibration is being performed. The welding output is NOT energized during the auto calibration
procedure. The prompts on the display will indicate when the calibration is complete. If the calibration is
interrupted or fails, the procedure should be repeated.
Auto calibration should be performed whenever the wire or gun is changed.
P.80

Sense From Studs

Use this option for diagnostic purposes only. When power is cycled, this option is automatically reset to False.
False = Voltage sensing is automatically determined by the selected weld mode and other machine settings
(default).
True = Voltage sensing is forced to "studs".
P.81

Electrode Polarity

Used in place of DIP switches for configuration of the electrode sense lead. This option allows selection of the electrode
voltage sense polarity. Most GMAW welding procedures use Electrode Positive welding. Most GTAW and some inner
shield procedures use Electrode Negative welding.
Positive Electrode Welding (default).
Negative Electrode Welding.
This option will only appear in the menu if the feedhead board does not have a dip switch to set the polarity, and the
power source does not support auto-hardware sense lead configuration. If this option does not appear in the menu,
voltage sense polarity can be selected using the dip switches.
P.82 Voltage Sense Display
Allows viewing of Voltage Sense Lead Selection to aid in troubleshooting. The configuration is displayed as a text
string on the lower display whenever the output is enabled. This parameter is not saved on a power cycle, but will
be reset to False.
P.99 Show Test Modes
Most power sources contain weld modes used for calibration and test purposes. By default, the machine does not
include test weld modes in the list of weld modes that are available to the operator. To manually select a test
weld mode, set this option to "Yes". When the power source is turned off and back on again, the test modes will
no longer appear in the mode list. Test weld modes typically require the machine output to be connected to a grid
load and cannot be used for welding.
P.100 View Diagnostics
Diagnostics are only used for servicing or troubleshooting the Power Wave system. Select "Yes" to access the
diagnostic options in the menu. Additional parameters will now appear in the setup menu (P.101, P.102, etc).
