5.2.7.8 Up/down speed
Functionality
Press and hold the up push-button:
Increase current up to the maximum value (main current) set in the power source.
Press and hold the down push-button:
Decrease current to the minimum value.
Use the machine configuration menu
> see 5.8 chapter
to set the up/down speed parameter
which
determines the speed with which a current change becomes effective.
5.2.8 Operating modes (functional sequences)
The parameters that can be set in the machine control function sequence are dependent on the welding
task selected. This means that if no pulse variant was selected, for example, no pulse parameters will be
available to set in the function sequence.
