Parameter Definition
P.7 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 fol-
lowing:
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.
Note: The range was changed to -90 to +90 for the PF25M in WD software S28539-3.
Default value remains at 0.
P.8 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.
"Solenoid (auto) = This selection only applicable to PWC300. The MIG solenoid will turn on and off auto-
matically while TIG welding.
"Feeder Solenoid" = No applicable to PWC300. The internal (feeder) MIG solenoid will turn on and off
automatically while TIG welding.
"Pwr Src Solenoid" = Not applicable to PWC300. 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 knob, 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.
P.9 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).
P.14 Reset Consumable Weight
Use this option to reset the initial weight of the consumable package. Press the Right Button to reset the
consumable weight. This option will only appear with systems using Production Monitoring.
