MAIN - Programming
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.
6.3 Parameters in operating mode Spot Welding / Interval
If the operating mode "Spot welding" is active, you have to enter the values
for the parameters "Spot welding time" and "Pause time" (sec).
