6 MAINTENANCE
6.1 Overview
NOTE!
Regular maintenance is important for safe and reliable operation.
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.
6.2 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.
Note: Make sure you turn both springs
the same amount.
Welding torch
• Cleaning and replacement of the welding torch's wear parts should take place at
regular intervals in order to achieve trouble-free wire feed. Blow the wire guide clean
regularly and clean the contact tip.
