2.Worn work cable or poor work

connection.

3.Wrongpolarity.

4.The gas nozzle is extended

beyond the contact tip or the wire

5.Poor gas shielding on processes

requiringgas.

1.Improper procedures or tech-

niques.

1.The software in the POWER

FEED™ 25M NNS must be
upgraded.

1.Replacethecontacttip.

2.Verify all work and electrode con-
