POSSIbLE AREAS OF MISADJUSTMENT(S)

RECOMMENDED

COURSE OF ACTION

General degradation of the weld per-	1.Check for feeding problems, bad
formance	connections, excessive loops in
	cabling, etc.
	2. Verify weld mode is correct for
	processes.
	3. The power source may require
	calibration.
	4. Check the actual current dis-
	played on the Power Feed 10 vs.
	actual current measured via exter-
	nal meter.
	5. Check the actual voltage dis-
	played on the Power Feed 10 vs.
	actual voltage measured via exter-
	nal meter.
	6. Check the actual WFS displayed
	on the Power Feed 10 vs. actual
	WFS measured via external
	meter.

Excessively long and erratic arc.	1. Check for proper configuration
	and implementation of voltage
	sensing circuits.

If Wire Feed Speed is in Question.	1. Check system with K283 speed
Inch Per Minute = (IPM)	meter tester.
	2. Manual Check by:
	• Turning off all run in features of
	the feeder. Cut wire flush to
	weld gun electrode tip. Feed
	wire for 6 seconds. Measure
	feed wire length from the end of
	the electrode tip to the end of
	the feed wire. Multiple 10 to the
	measured length.
	Example: You measure 24” , then
	your results will be 240 IPM.
	(10 x 24 = 240 IPM)

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
