CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

Connection of LN-7 or LN-8 to the DX450

1.Shut the welder off.

2.Connect the LN-7 or LN-8 per instructions on the appropriate connection diagram in Section F.

3.Set the "WIRE FEEDER VOLTMETER" switch to either "+" or "-" as required by the electrode being used.

4.Set the "MODE" switch to the "CV WIRE " posi- tion.

5.Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

6.Set the "WELD TERMINALS" switch to the "REMOTELY CONTROLLED" position.

7.Set the "IDLE" switch to the "HIGH" position.

Connection of LN-15 to the DX450

1.Shut the welder off.

2.For electrode Positive, connect the electrode cable to the "+" terminal of the welder and work cable to the "-" terminal of the welder. For elec- trode Negative, connect the electrode cable to the "-" terminal of the welder and work cable to the "+" terminal of the welder.

3.Across The-Arc Model:

•Attach the single lead from the front of the LN-15 to work using the spring clip at the end of the lead. This is a control lead to supply current to the wire feeder motor; it does not carry welding current.

•Set the "WELD TERMINALS" switch to "WELD

TERMINALS ON".

•When the gun trigger is closed, the current sens- ing circuit will cause the DX450 engine to go to the high idle speed, the wire will begin to feed and the welding process started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed.

4.Control Cable Model:

•Connect Control Cable between Engine Welder and Feeder.

•Set the "WELD TERMINALS" switch to

"REMOTELY CONTROLLED"

•Set the MODE switch to the "CV-WIRE " position.

•Set the "WIRE FEEDER VOLTMETER" switch to either "+" or "-" as required by the electrode polar- ity being used.

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

•Set the "IDLE" switch to the "AUTO" position.

•When the gun trigger is closed, the current sens- ing circuit will cause the DX450 engine to go to the high idle speed, the wire will begin to feed and the welding process started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed.
