Parameter
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) = The MIG solenoid will turn on and off automatically while TIG welding.
"Feeder Solenoid" = The internal (feeder) MIG solenoid will turn on and off automatically while TIG weld-
ing.
"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.
If a dedicated TIG gas solenoid is installed, as in the Advanced AC Module, all TIG gas control will use that
solenoid and this menu option will be irrelevant.
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).
On dual-head Power Feed 84 Feeders, a different setting can be used for each head. The operator will be
prompted to select which head to edit before the setting can be changed.
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.
