6.24 Crater filling
Crater filling makes a controlled reduction in the heat and size of the weld pool possible
when completing the weld. This makes it easier to avoid pores, thermal cracking and crater
formation in the weld joint.
• Crate filling is set in the weld data setting menu under stop data.
6.25 Burnback time
Burnback time is a delay between the time when the wire starts to brake until the time when
the power source switches off the arc voltage. Too short burnback time results in a long wire
stickout after completion of welding, with a risk of the wire being caught in the solidifying weld
pool. Too long a burnback time results in a shorter stickout, with increased risk of the arc
striking back to the contact tip.
• Burnback time is set in the weld data setting menu under stop data.
6.26 Stop phases
Stop phases are mainly used for setting crater filling.
The following can be set for Stop phase1
ON
• Time s
Time for welding in phase 1.
• Arc voltage %
In percent of set voltage
• Wire feed %
In percent of set wire feed
• Welding current %
In percent of set welding current
• Travel speed %
In percent of set travel speed
The following can be set for Stop phase2
ON
• Time s
Time for welding in phase 2.
• Arc voltage %
In percent of set voltage
• Wire feed %
In percent of set wire feed
• Welding current %
In percent of set welding current
• Travel speed %
In percent of set travel speed
• Stop phases are set in the weld data setting menu under stop data.
6.27 Dynamic regulation
The dynamic regulation function is developed for multiple electrode welding and alters the
characteristics of the power source. The characteristics of the power source are calculated
from the set wire data.
• Dynamic regulation is selected in the weld data setting menu.
6.28 Control parameters
In some applications the function Control parameters is displayed instead of Dynamic
control. There are two settings to make under Control parameters:
• Dynamics - Affects the dynamic characteristics
• Inductance - Higher values give a wider weld pool and less spatter. Lower values produce
a stable, concentrated arc and a harsher sound.
• Control parameters are selected in the weld data setting menu.
