are factory set as “relative programs”, i.e. they are dependent on a percentage
of the WF value of main program P
A
(switching between relative and absolute wire feed values,
see chapter “WF Speed Switching (absolute / relative)”.
Changes to the welding parameters can only be made when the key switch is in position "1".
