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

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 44.

Welding gun

Cleaning and replacement of the welding gun'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.

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

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