Turning on the power source
Turn on the mains power by turning the mains switch to the ”1” position.
Turn the unit off by turning the switch to the ”0” position.
Whether the mains power supply is interrupted or the power unit is switched off in the
normal manner, welding data will be stored so that it is available next time the unit is
started.
MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized personnel) may
remove the safety plates to connect or carry out service, maintenance or repair work on
welding equipment.
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.
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.
