Parameter Definition
P.7 Gun Offset Adjustment
Range: -30 to 30 (default = 0)
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:
• Release the pressure arm on both the pull and push wire drives.
• Set the wire feed speed to 200 ipm.
• Remove wire from the pull wire drive.
• Hold an rpm meter to the drive roll in the pull gun.
• Pull the trigger on the push-pull gun.
• Measure the rpm of the pull motor. The rpm should be between 115 and 125 rpm. If neces-
sary, decrease the calibration setting to slow the pull motor, or increase the calibration setting
to speed up the motor.
P.8 TIG Gas Control
Allows control over which gas solenoid actuates while TIG welding.
• Valve (manual) = No MIG solenoid will actuate while TIG welding, gas flow is manually con-
trolled by an external valve.
• Feeder Solenoid = The internal (feeder) MIG solenoid will turn on and off automatically while
TIG welding.
• Power source Solenoid = Any gas solenoid connected to the power source will turn on and off
automatically while TIG welding.
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
Range: Off to 10.0 seconds (default = Off)
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
Only appears in the list with systems using Production Monitoring. Use this option to reset the
initial weight of the consumable package. Press the right Mode Select Button to reset the con-
sumable weight.
