Gouging
‰ Gouging is used for working out the roots or faulty
points and serves for preparing the weld seam.
‰ A special torch is required for gouging that has car-
bon electrodes and compressed air connection.
 Press and hold the electrode button 50 (Control Pro)
or 58 (Basic Plus) for at least 2 seconds.
9 The Electrode CEL LED 49 flashes.
 Set the desired current by rotating the control knob

Up / Pulses (Control Pro)
‰ The Up and Pulses function can be activated or de-
activated. The Up (LED 37) and Pulses (LED 36)
functions are only available in an active state.
‰ If Up / Pulses is deactivated, the Arc Force can be
selected or deselected directly (without pressing but-
ton 30 several times).

Hold functionality
‰ After the welding, with Hold = 5, 10 or On, the aver-
age values of the last welding task are visible in the
display for 5 sec., 10 sec. or permanently, the LED
