OPERATION POWER FEED™ 25M NNS
Parameter Definition
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 manu-
ally controlled by an external valve.
"Feeder Solenoid" = The internal (feeder) MIG solenoid will turn on and off automati-
cally while TIG welding.
"Pwr Src Solenoid" = 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 con-
trolled 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.
P.18 Wire Drive Gear Ratio
This option selects the Wire Drive Gear Ratio that will be used. The possible selectable values
are read from the Wire Drive on startup. For semi-automatic systems, if the feedhead board
has dip switches, this option does not appear in the menu. Gear ratio can be selected using the
dip switches.
Note: Changing this value will cause the system to reset.
P.20 Display Trim as Volts Option
This option determines how trim is displayed.
False = The trim is displayed in the format defined in the weld set (default).
True = All trim values are displayed as a voltage.
Note: This option may not be available on all machines. The power source must support this
functionality, or this option will not appear in the menu.
