MIG SUPERPULSE (Aristo SuperPulse
t
) is used for improved control of the weld
pool and the solidification process. The weld pool has time to solidify partially
between each pulse.
Advantages of using MIG SUPERPULSE:
S
Less sensitive to variations in the root gap
S
Better control of the wel pool during position welding
S
Better control of penetration and penetration profile
S
Less sensitive to uneven heat evaporation
MIG SUPERPULSE can be seen as a programmed changeover between two
MIG/MAG settings. The time intervals are determined by the primary and secondary
phase time settings.
MIG SUPERPULSE takes up two positions in the weld data memory. The primary
data in an odd memory position and the secondary data in the following even
memory position. One effect of this is that a digital remote control unit cannot use the
even memory positions when MIG SUPERPULSE data is saved.
Welding always starts in the primary phase. When hot start is selected primary data
will be used during the hot start time in addition to the phase time for the primary
data. Crater filling is always based on secondary data. When a stop command has
been activated during the primary phase time the process immediately switches to
secondary data. The weld completion is based on secondary data.
