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.
