RTF start ramp

The RTF start ramp function prevents the energy input at the start of welding from being too high and too
fast should the user press the remote control pedal too fast and too strongly.
Example:
The user sets the main current at the welding machine to 200 A. The user presses the remote control pe-
dal very quickly down by approx. 50% of the pedal travel.
• RTF start ramp switched on: The welding current increases in a linear (slow )ramp to approx. 100 A.
• RTF start ramp switched off: The welding current immediately jumps to approx. 100 A.
The RTF start ramp function is activated/deactivated by the parameter
menu > see 5.6 chapter.
