POWER FEED™ 25M
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 auto-
matically 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 tung-
sten 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 set-
ting 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 consum-
able weight. This option will only appear with systems using Production Monitoring.
