3.3.1. Choosing the welding method
Normal MIG/MAG welding:
with a separate wire feed and voltage regulation can be chosen in the 1-MIG position.
Curve number ”00” provides a free wire feed range between 1-18 m/min. The voltage
can be set between special pre-programmed limits depending on the wire feed. Curve
number ”01” wire feed speed and voltage are not depended on each other. When curve
”01” is selected, the wire feed speed and voltage will be independent of one another.
Synergic MIG/MAG welding (1-MIG)
Synergic MIG/MAG welding (1-MIG): MIG welding in which the wire feed speed
determines all the other welding parameter values, allowing the adjustment of welding
power with a single knob. Choose the appropriate synergy curve for the ller wire and
shielding gas to determine how the wire feed speed affects the pulse parametres.
Synergic Pulse MIG welding:
through this welding method, based on pulsing the welding current, the ller metal on the
workpiece is kept spatter-free. The power source pulse parameters change automatically
(synergy) enabling welding power regulation using a single knob. Choose the appropriate
synergy curve for the ller wire and shielding gas to determine how the wire feed speed
affects the pulse parametres.
3.3.2. Selecting 1-mig/pulse mig synergy curves
The program number of the synergy curve is selected using the plus-minus buttons and is displayed
on ”SYNERGIC PRG”.
The middle display is actual material group display (eg. SS, AL, CUS, FE, GEN). Wire diameter
(mm) can be seen on the right side. This information will only be displayed for a while.
The ”PRG INFO” button gives more curve information:
One press will revert to the material group and diameter display, a second will display the type
number of the material and a third run through the gas consistency components one by one.
