OPERATION

MAKING A TEST WELD AND ADJUSTING LN-9 GMA RESPONSE AND STARTING CHARACTERISTICS

ADJUST THE POWER SOURCE

DC-250, DC-400, or DC-600

1.Connect electrode lead to terminal of desired polarity.

2.Set toggle switch to same polarity as the electrode cable connection.

3.Set toggle switch to "Output Control Remote."

4.Set mode switch to the desired position for the process to be used.

NOTE: Since the LN-9 GMA cannot control the fixed OCV of R3S power sources, starting difficulties may be experienced when strik- ing the arc of processes which use a low voltage or a narrow voltage range. The following steps should remedy this difficul- ty:

1 . The electrode stickout when starting should be as close to procedural length as possible, and the tip of the electrode should be clean and held nearly touching the work.

2.Install the R3S voltage triangle to the position higher than the desired arc voltage, provided it does not result in out of range shutdown of the LN-9 GMA while welding.

PULSE POWER 500, DC650 PRO, V300

CV-400, CV-500-I

1.Connect electrode lead to terminal of desired polarity.

2.Connect #21 control lead to the work polarity ter- minal (+21 or -21), at the terminal strip, matching the same polarity as the work cable connection.

3.Set toggle switch to "Output Control Remote."

R3S-400, R3S-600, R3S-800

1.Connect electrode lead to terminal of desired polarity.

2.Set toggle switch to same polarity as the electrode cable connection.

3.Set the toggle switch to "Remote."

4.Install voltage triangle to a position as close as possible to desired arc voltage.

Refer to each machine Instruction Manual. The LN-9 GMA requires the K442-1 Pulse Power Filter Kit. (See the Accessories section of this manual.)

ADJUST THE LN-9 GMA CONTROLS

1.Set the "Electrode Polarity" switch to same polarity as the electrode lead.

2.Check that "Feed Direction" is set to forward.

3.Set the "Trigger Interlock" switch as desired.

4.Set the "Meter Reading" switch to "Wire Speed" and adjust the "Wire Speed" rheostat so the meter reads the desired wire feed speed.

5.Set the "Meter Reading" switch to "Volts" and adjust the "Volts" rheostat so the meter reads the desired arc voltage. IMPORTANT: Make certain this setting is within the voltage output range of the power source setting.

6.Load the LN-9 GMA with electrode.
