5.3 Fan control

The power source has a time control that means that the fans continue to run for 6.5

minutes after welding has stopped, and the unit switches to energy-saving mode.

The fans start again when welding restarts.

The fans run at reduced speed for welding currents up to 110 A, and at full speed for

higher currents.

5.4 Overheating protection

The welding power source has overheating protection that operates if the

temperature becomes too high. When this occurs the welding current is interrupted

and a fault code is displayed on the control panel.

The overheating protection resets automatically when the temperature has fallen.

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.

Only those persons who have appropriate electrical knowledge (authorized

personnel) may remove the safety plates.

6.1 Inspection and cleaning

Power source

Check regularly that the welding power source is not clogged with dirt.

How often and which cleaning methods apply depend on: the welding process, arc

times, placement, and the surrounding environment. It is normally sufficient to blow

down the power source with dry compressed air (reduced pressure) once a year.

Clogged or blocked air inlets and outlets otherwise result in overheating.

Welding torch

The welding torch's wear parts should be cleaned and replaced at regular intervals in

order to achieve trouble-free welding.
