MAIN - Progr. (Programming)
Step modulation
The welding practice often requires working with different main param-
eters. The power continuation is ensured by shortly pressing the torch
trigger (< 0.5 sec).
Use the function "Step modulation" to determine the step width of the
increase or the reduction of the wire speed or power per keystroke (Step).
A maximum wire speed change of 9.9 m/min per step is permitted!
Number of steps
Use the function "Number of steps" to determine the maximum number
of steps.
Max. 10 steps are possible. When the max. number of steps has been
reached, the wire speed per torch keystroke reduces by the adjusted step
modulation.
DuoPulse
All operating modes allow to switch on the "DuoPulse" function.
(Menu "functions", "DuoPulse"). If the "Expert Mode" function is active,
further parameters are available there, see Page 64.
DuoPulse modulation
A second weld parameter set can be generated by means of the "DuoPulse"
function. Based on the set basic value, a second weld parameter can be
generated which is higher or lower than the basic value.
By means of a defined frequency there is a switch-over between the two
parameter sets. The appearance of the weld seam surface can be formed by
the defined change of parameters. During root welding, defined cool-down
times can be reached depending on the setting. The "DuoPulse" function is
available for all gas/material combinations.
The characteristic curve is already provided with a 2nd parameter set
which is useful for welding. The display shows "- 0 - "and a corresponding
value for the wire speed in m/min. If you want to deviate from the base
setting, use the rotary knob 3 to enter a value between -99 and +99. The
appropriate absolute value changes as well.
DuoPulse frequency
This function is used to change the switching speed (frequency) of both
parameter sets.
The characteristic curve is already provided with a useful frequency for
welding.
The display shows "- 0 - "and an appropriate value for the frequency in Hz.
If you want to deviate from the base setting, use the rotary knob 3 to enter
a value between -99 and +99. The appropriate absolute value changes as
well.
