RECOMMENDED

COURSE OF ACTION

Bad Weld Ending.

1. Burnback Disabled.

1. From the DeviceNet tab of the

 

 

 

 

 

 

Diagnostics Utility, select Monitor. The

 

 

 

 

 

 

Monitor window will be displayed.

 

 

 

 

 

 

Verify under the “State Enabled” that

 

 

 

 

 

 

“Burnback” is present.

 

 

2.

Burnback Time.

2.

Verify that Burnback Time has a value

 

 

 

 

 

 

other than 0.

 

 

3.

Analog Scans Between Updates.

3.

The DeviceNet tab of the Diagnostics

 

 

 

 

 

 

Utility displays the POWER WAVE®ʼs

 

 

 

 

 

 

“Analog Scans Between Updates” and

 

 

 

 

 

 

“I/O Scans/Sec.” Verify that “Analog

 

 

 

 

 

 

Scans Between Updates” is ¼ of “I/O

 

 

 

 

 

 

Scans/Sec” value.

 

 

 

 

 

 

 

 

 

4.

Limit Error reported at the end of a

4.

Verify all welding settings for

 

 

 

 

weld.

 

Burnback and Crater states.

 

 

 

 

 

 

 

 

5.

Fan Out.

5.

From the DeviceNet tab of the

 

 

 

 

 

 

Diagnostics Utility, select Monitor.

 

 

 

 

 

 

Verify under “Analog Input Fan Out”

 

 

 

 

 

 

that Burnback is present for all

 

 

 

 

 

 

analogs in.

 

 

6.

Welding set points.

6.

Verify Burnback set points for work

 

 

 

 

 

 

point, trim, and wave values.

 

 

 

 

 

 

 

 

7.

Analog Hysteresis.

7.

From the DeviceNet tab of the

 

 

 

 

 

 

Diagnostics Utility, select Configure.

 

 

 

 

 

 

Verify in “Analog Input Channels” that

 

 

 

 

 

 

the Hysteresis settings are all 0.

 

 

 

 

 

 

 

 

8.

Gas.

8.

Verify Gas is turned on.

 

 

 

 

 

 

Bad Welding.

1. Analog Scans Between Updates.

1.

The DeviceNet tab of the Diagnostics

 

 

 

 

 

 

Utility displays the POWER WAVE®ʼs

 

 

 

 

 

 

“Analog Scans Between Updates” and

 

 

 

 

 

 

“I/O Scans/Sec.” Verify that “Analog

 

 

 

 

 

 

Scans Between Updates” is ¼ of “I/O

 

 

 

 

 

 

Scans/Sec” value.

 

 

2.

Voltage Sense Leads.

2.

Verify voltage sense leads are proper-

 

 

 

 

 

 

ly connected and configured as

 

 

 

 

 

 

described in the instruction manual.

 

 

 

 

 

 

 

 

3.

Analog Hysteresis

3.

From the DeviceNet tab of the

 

 

 

 

 

 

Diagnostics Utility, select Configure.

 

 

 

 

 

 

Verify in “Analog Input Channels” that

 

 

 

 

 

 

the Hysteresis settings are all 0.

 

 

 

 

 

 

 

 

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.
