WIRE FEED MODULE™

DESIGN FEATURES

• Easy access to the controls located on the welder

control panel.

• Greatly enhanced welding arc performance. Now a

wider range of wire electrodes and processes are

supported by this device.

• Improved arc starting characteristics.

• Low spatter MIG welding with CO

• Built into the WFM is a power contactor that pro-

vides a "COLD" electrode when the gun trigger is

released.

• Simplified field installation process. All control wiring

connections between the welder, the control panel,

and the WFM are easily made with in-line plug type

connections.

• Includes thermostatic protection to protect the

welder from over current and over temperature.

RECOMMENDED WIRE FEEDERS AND ACCESSORIES

The WFM is designed to work with the complete

family of LN-7, LN-25, and LN-23P wire feeders.

Please refer to the connection diagram in the back of

this manual for details.

ADDITIONAL SAFETY PRECAUTIONS

The output terminals are energized when the

engine is running. The CV output will be de-ener-

gized only if WFM mode switch is in remote posi-

tion.

WIRE FEED MODULE OPERATION

OUTPUT

For constant voltage welding, place the CC/CV mode switch in the

CV position. Connect the wire feeder to the CV negative output

terminal and connect the work to the positive standard output ter-

minal. For electrode positive, reverse the output leads. The nega-

tive standard output terminal is not used for CV welding of either

polarity. Refer to diagrams section to determine the correct con-

nection to the remote control receptacle.

Gas.

WARNING

When the WFM is in the "CV" mode, the maximum auxiliary power

will be reduced by 25%. To obtain maximum auxiliary output,

place the CC/CV switch in the CC position.

If the current rating of the welder is exceeded, a thermostat will

reduce the output voltage to approximately 5 volts. The thermo-

stat will reset automatically as the machine cools. If the thermo-

stat trips, lower the wire feed speed and output voltage or reduce

Duty Cycle.

CONTROLS

The output voltage is set with the voltage control dial mounted on

the control panel. Set the "Current Range Selector" to the "190-

120" position for optimum welding characteristics. Changing the

"Current Range Selector" affects arc characteristics. Setting the

"Current Range Selector" one position to the right of the "190-

120" position will give a softer arc. If this switch is placed one

position to the left from the "190-120" set point, the machine will

produce a crisp arc characteristic. The setting of the "Fine

Current Adjustment" has no effect on the operation in "CV" mode.

For Coarse Current Control on the SAE-300 see operator manual.
