Synergic Function
The operator simply sets the welding current like MMA or TIG welding 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 given a number from 1-17, this is accessed on the L display
(3) using the L knob (14), indicator 'P'. To select the relevant program for the welding
application, check the chart printed on the inside door of the welding machine or further
on in this manual.
Single Pulse Function
Pulse allows the arc to enter spray transfer at lower currents and feed speeds than
manual allowing faster welding with high deposition and smaller heat effected zones due
to the extra arc energy provided at peak of pulse. Used for stainless or aluminum edge or
seam welds.
Double-Pulse Function
Double pulse allows more precise control of heat input as “peak” is offset by “base”
allowing puddle stability. It is mainly used in aluminum alloy welding for strong penetration
with narrow bead and smooth surface. It can produce the ripple effect of a TIG weld
without torch modulation. Dual pulse reference waveform as shown below:
