WIRE FEEDER CONTROLS

The third section of the control panel is the wire feeder controls (Items 12-21 on page 8). An overview of each 

wire feeder control is provided below. For more detailed information, refer to the Lincoln Operating manual.

VOLTS

Displays actual voltage during welding

CURRENT

Displays actual current (amps) during welding

WIRE FEED SPEED

Controls the feed speed of the wire. Turn left for slower speeds; right for higher 

speeds. 

WIRE DIRECTION

Controls the direction the wire is being fed through the feeder. UP to return wire to 

the spool. DOWN to feed the wire to the gun in order to weld.

FLUX VACUUM

Turns the Flux Recovery Vacuum ON and OFF.

PREFLOW

Controls flow of shielding gas to the work before the arc is established. The gas 

solenoid valve is energized immediately when the gun trigger is closed, but the 

time delay before the wire feeder is energized is adjustable from 0 to 1.5 seconds. 

Turn the knob LEFT for shorter delays, RIGHT for longer delays.

POSTFLOW

Controls flow of shielding gas to the work after the welding has stopped. 

Adjustable from 0.5 to 4.5 seconds. Turn the knob LEFT for shorter delays, RIGHT 

for longer delays.

PURGE / COLD INCH 

Control some wire feeder functions without energizing the welding power source. 

The momentary UP position energizes the gas solenoid, but not the wire feeder or 

welding power source. The momentary DOWN position energizes the wire feeder 

but not the gas solenoid or the welding power source. 

BURNBACK

Provides a precise time delay that allows the wire to be burned off at the end 

of the weld. This is useful for those applications where higher speed, fine wire 

feeding is used and there is a tendency for the electrode to overrun at the end of 

the weld and cause “sticking” in the crater. The delay is adjustable for optimum 

burnback depending on wire size, process, procedure, etc.  

When entering data, use the diameter of the cylinder along whose intersection the cut has been made. Usually 

this will be the inside diameter of the nozzle or the outside diameter of the pipe it fits on. This will also allow for 

any bevel, if necessary. If no offset, enter “0” or just press “Enter”.

NOTE: If the STOP / RESUME button is pressed, the machine will be in pause mode, and cannot be pro-

grammed. Press the RESET button to get back to the ready mode for programming.

DATA ENTRY

When entering data with the pendant keypad, multiply inches, degrees, or seconds by 100 and enter the 

number without a decimal point.  For metric dimensions, multiply mm X 10 or cm X 100.

Example: 350 for 3.5 inches,

800 for 80 mm, on metric machines

Press “ENTER” on the keypad after the number is entered.

SAVING PROGRAMS

The machine has 100 storage areas or welds,  numbered 0 to 99 in memory. Push the “C” button on the 

pendant keypad to change (or set) the program number and enter the desired number. Program data is 

retained until reprogrammed.  At any time, one of these numbers is selected, it will stay selected even when 

power is shut off and turned back on, it will not change until the program number is changed by the operator. 

Settings for time delay and number of passes are not saved as part of a program.
