6 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
6.1 Inspection and cleaning
Wire feed unit
Check regularly that the wire feed unit is not clogged with dirt.
Cleaning and replacement of the wire feed unit mechanism's worn parts should
take place at regular intervals in order to achieve trouble-free wire feed. Note
that if pre-tensioning is set too hard, this can result in abnormal wear on the
pressure roller, feed roller and wire guide.
The brake hub
The hub is adjusted when delivered, if
readjustment is required, follow the instructions
below. Adjust the brake hub so that wire is slightly
slack when wire feed stops.
Adjusting the braking torque:
Turn the red handle to the locked position.
Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque
Turn the springs counter-clockwise to increase the braking torque. NB: Turn
both springs the same amount.
Welding gun
The welding gun's wear parts should be cleaned and replaced at regular
intervals in order to achieve trouble-free wire feed. Blow the wire guide clean
regularly and clean the contact tip.
