MAINTENANCE

Regular maintenance is important for safe, reliable operation.
Maintenance must be executed by a professional.
Only those persons who have appropriate electrical knowledge (authorised
personnel) may remove the safety plates.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1

Inspection and cleaning

Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced pressure. More
frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating. To avoid this you can use
an airfilter.
The airfilter is an accessory. Ordering number can be found on page 238.
Welding gun
Cleaning and replacement of the welding gun's wear parts should take place at
S
regular intervals in order to achieve trouble–free wire feed. Blow the wire guide
clean regularly and clean the contact tip.
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.
7.2

Topping up the coolant

We recommend a 50/50 % mixture of water and ethylene glycol.
