DUAL PULSE FREQUENCY
Set pulse frequency, as shown in Figure regulating the value of time T, namely, ripple pattern of density
regulation. Higher Hz produces many short ripples with slightly lower penetration.
DUAL PULSE DUTY
Set strong pulse time T1 (peak) for penetration and low-frequency cycle T2 ratio (cooling), namely the
regulation of the proportion of the ripple pattern on weld puddle surface and resulting depth in groove.
Synergic Function (12) (13)
This makes the setup of MIG welding more simple, the operator simply sets the welding current like
MMA and the machine calculates the optimal voltage and wire speed for the material type, wire
type and size and shielding gas being used. Obviously other variables such as welding joint type and
thickness, air temperature affect the optimal voltage and wire feed setting, so the program provides
a voltage fine tuning function for the synergic program selected. Once the voltage is adjusted in a
synergic program, it will stay fixed at this variation when the current setting is changed. To reset the
voltage for a synergic program back to factory default, change to another program and back again.
The synergic programs are adjusted by using key (9) and (12) (14). To select the relevant program for the
welding application, check the chart printed on the inside door of the wire feeder or further on in this
manual.
