1. STATUS LED

FIGURE b.2

 

The status LED indicates system status.

Normal A. WIRE FEED SPEED/AMMETER DISPLAY

 

operation is a steady green light.

 

 

Note: During normal power-up, the LED may flash red and/or green as the equipment performs self tests.

LED condition

Definition

 

 

Steady green

System okay. The power source and

 

wire feeder are communicating nor-

 

mally.

 

 

blinking green

Occurs during a reset and indicates

 

the power source is identifying each

 

component in the system. This is nor-

 

mal for the first 10 seconds after

 

power-up, or if the system configura-

 

tion is changed during operation.

 

 

Alternating

Non-recoverable system fault. If the

green and red

power source or wire feeder status

 

LED is flashing any combination of

 

red and green, errors are present in

 

the system. Read the error code

 

before the machine is turned off.

 

Instructions for reading the error code

 

are detailed in the Service Manual.

 

Individual code digits are flashed in

 

red with a long pause between digits.

 

If more than one code is present, the

 

codes will be separated by a green

 

light.

 

To clear the error, turn the power

 

source OFF, and then back ON to

 

reset. See troubleshooting section.

 

 

Steady red

Non recoverable hardware fault.

 

Generally indicates a problem with

 

the cables connecting the wire feeder

 

to the power source.

 

 

blinking red

Not applicable.

 

 

2.DIGITAL METERS AND OUTPUT ENCODER KNObS (See Figure B.2)

The primary weld procedure settings are controlled and displayed using digital meters and output encoder knobs located at the top of the Power Feed™ 10M Single Wire Feeder control panel.

WFS AMPS

VOLTS TRIM

This meter displays either the wire feed speed or cur- rent value (Amps) depending upon welding process (Mode) being used and the status of the wire feeder and power source. Written below the display is "WFS" and "Amps". An LED light illuminates which value is being displayed on the meter. The knob below the meter adjusts the value displayed on the meters.

Prior to Welding

Description

CV Welding Processes

Meter displays the preset

 

WFS value.

CC Welding Processes

Meter displays the preset

 

Amps.

During Welding

 

An Weld Processes

Meter displays displays the

 

actual average welding

 

Amps.

After Welding

 

An Weld Processes

The meter holds the actual

 

current value for 5 sec-

 

onds. The display blinks to

 

indicate the Power Feed™

 

10M Single Wire Feeder is

 

in the "Hold" period. If the

 

output is adjusted while in

 

the "Hold" period, the

 

Power Feed™ 10M Single

 

Wire Feeder will revert to

 

the "Prior to welding" dis-

 

play described above.

Note: If the output knob for the WFS/AMPS is adjust- ed while the Power Feed™ 10M Single Wire Feeder is in the “Hold” period, the Power Feed™ 10M Single Wire Feeder will immediately revert to the “Prior to Welding” display.

The default wire feed speed units are inches/minute and can be changed to meters/minute by entering the "Set-up Menu" in this Operation Section. The wire feed speed is calibrated to within ±2%. Refer to the power source man- ual for calibration specifications of the ammeter.
