P007 Gun Offset Adjustment This option adjusts the wire feed speed calibration of the pull motor of a push-
pull gun. This should only be performed when other possible corrections do not
solve any push-pull feeding problems. An rpm meter is required to perform the
pull gun motor offset calibration. To perform the calibration procedure do the
following:
1. Release the pressure arm on both the pull and push wire drives.
2. Set the wire feed speed to 200 ipm.
3. Remove wire from the pull wire drive.
4. Hold an rpm meter to the drive roll in the pull gun.
5. Pull the trigger on the push-pull gun.
6. Measure the rpm of the pull motor. The rpm should be between 115
and 125 rpm. If necessary, decrease the calibration setting to slow the
pull motor, or increase the calibration setting to speed up the motor.

The calibration range is -30 to +30, with 0 as the default value.
P008 TIG Gas Control This option allows control over which gas solenoid actuates while TIG welding.

"Valve (manual)" = No MIG solenoid will actuate while TIG welding, gas flow
is manually controlled by an external valve.

"Feeder Solenoid" = The internal (feeder) MIG solenoid will turn on and off
automatically while TIG welding.

"Pwr Src Solenoid" = Any gas solenoid connected to the power source will
turn on and off automatically while TIG welding. This selection will not
appear in the list if the power source does not support a gas solenoid.
Notes: Preflow is not available while TIG welding. Postflow is available - the
same Postflow time will be used in MIG and TIG. When machine output on/off
is controlled via the upper right Control [10], gas flow will not start until the
tungsten touches the work. Gas flow will continue when the arc is broken until
the Postflow time expires. When machine output on/off is controlled via an arc
start switch or foot Amptrol, gas will begin flowing when the output is turned on
and will continue flowing until the output is turned off and the Postflow time
expires.
P009 Crater Delay This option is used to skip the Crater sequence when making short tack welds.
If the trigger is released before the timer expires, Crater will be bypassed and
the weld will end. If the trigger is released after the timer expires, the Crater
sequence will function normally (if enabled).

OFF (0) to 10.0 seconds (default = Off)
P014 Reset Consumable
Weight
Use this option to reset the initial weight of the consumable package.
"No" = Weight reset annulment.
"Yes" = Weight reset accept.
In addition it shows the current wire weight.
Note: This option will only appear with systems using Production Monitoring.
P016 Push-Pull Gun Control
Behavior This option determines how the potentiometer on the Push/Pull torch will
behave.

"Gun Pot Enabled" (default) = The welding wire feed speed is always
controlled by the potentiometer on the push-pull gun. The Left Control [9] is
only used to adjust Start and Crater wire feed speed.

"Gun Pot Disabled" = The wire feed speed is always controlled by the Left
Control [9]. This setting is useful when the operator wishes to have wire
feed speed settings recalled from memories and not have the potentiometer
"overwrite" the setting.

"Gun Pot Proc A" = When in procedure A, the welding wire feed speed is
controlled by the potentiometer on the push-pull gun. When in procedure B,
the welding wire feed speed is controlled by the Left Control [9]. This setting
allows a fixed wire feed speed to be selected in procedure B and not have
the potentiometer "overwrite" the setting when the procedure changes.
