6. MAIN - Function
The display field is highlighted yellow if one function is active.
6.1 DuoPulse
If the function is active, a second welding parameter is generated from the
set basic value, 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. If the "Expert Mode" function
is active, further parameters are available there, see ""Expert Mode" (single
parameter mode)" on page 64
6.2 CleanStart
Clean Start is a special ignition routine which ensures a reliable and low
spatter arc ignition. The complete ignition routine runs in the millisecond
range. This results in an exceptionally low spatter ignition process.
6.3 Blow through
With this function the blow through valve gas/air in the QWD wire drive is
manually operated.
This function is only active as long as the button is pressed.
