6 MAINTENANCE
WARNING!
Be sure the branch circuit or main disconnect switch is off or electrical input circuit
fuses are removed from the power source main supply before attempting any
inspection or work on the inside of the wire feeder. Placing the power switch on the
welding machine in the off position does not remove all power from inside of the
equipment.
WARNING!
Inspection, troubleshooting, and repair of this equipment should be undertaken by a
competent individual having at least general experience in the maintenance and
repair of semi-conductor electronic equipment. Maintenance or repair should not be
undertaken by anyone without such qualifications.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer attempts
any work to rectify any faults in the product during the warranty period.
NOTE!
Regular maintenance is important for safe and reliable operation.
6.1 Inspection and cleaning
WARNING!
If uninsulated cable and parts are not replaced, an arc caused by a bared cable or
part touching a grounded surface may damage unprotected eyes or start a fire. Body
contact with bared cable, connector, or uncovered conductor can shock, possibly
fatally.
Wire feed unit
Regularly check that the wire feed unit is not clogged with dirt.
• Cleaning and replacement of worn parts in the mechanism of the wire feed should take
place at regular intervals in order to achieve trouble-free wire feeding.
NOTE!
If pre-tensioning is set too hard, this can result in abnormal wear on the pressure
roller, feed roller and wire guide.
