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 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 neces- sary, decrease the calibration setting to slow the pull motor, or increase the calibration set- ting to speed up the motor.The calibration range is -30 to +30, with 0 as the default value.

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 con-
	trolled by an external valve.
	"Solenoid (auto) = This selection only applicable to PWC300. The MIG solenoid will turn on and
	off automatically 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 out-
	put 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.
