FIGURE B.4 VV(CC) WIRESPEED SETTING

MAKING A WELD

SETUP

a. Connect work cable to metal to be welded. Work cable must make good electrical contact to the work. The work must also be grounded as stated in “Arc Welding Safety Precautions.”

b.Check that the LN-25 is properly connected to the power source for the polarity and process to be used, and appropriate power source settings are made for the procedure to be used. (Refer to power source operating and connection instructions.)

NOTE: If the K431-1 Remote Output Control Kit or K624-1 42V Remote Control Module is installed but the LN-25 is to be used without the K432 Remote Control Cable Assembly, then the Remote Board harness plug must be removed from the 16-pin receptacle on the Control Board and the jumper plug (T13498-21) reinstalled.

NOTE: If the K460-1 Pulse Power Adapter Kit is installed but the LN-25 is to be used without the K461 Pulse Power Control Cable Assembly, then the instructions for returning the unit to across the arc operation included with the Installation Instructions (L9636) must be followed.

c.Place the LN-25 conveniently near the work area in a location to minimize exposure to weld spatter and to avoid sharp bends in the gun cable.

d.Connect the LN-25 Clip Lead to work and set Po- larity Switch to same polarity as electrode.

e.Set WIRE FEED MODE switch to CV or CC, as appropriate for the power source, then set the proper DIAL RANGE and WIRE SPEED dial set- ting for the proper wire feed speed per the welding procedure:

For CV: Set dial to the calibrated IN/MIN desired. (Refer to Setting Constant Wire Feed Speed Section.)

For CC: Set dial to value determined from the

CCWire Speed Graph for the DESIRED IN/ MIN and ARC VOLTS to be used. (Refer to Setting Arc Sensing Wire Feed Speed Section.)

NOTE: If procedure permits a range of acceptable arc voltage, use the middle of the range to determine proper WIRE SPEED setting.

f. If using the optional Gas Flow Timer, set the de- sired PREFLOW TIME and POSTFLOW TIME.
