Instruction in synergy programming of the MWF
10/11/21
The KMX 550 and FLEX range with MWF10/11/21 can
be equipped with a synergy kit, which enables
synergetic adjustment of the welding machine.
Contrary to traditional MIG/MAG welding where ad-
justment of both welding current as well as welding
voltage is necessary, synergetic adjustment is
characterised by adjustment with only one knob.
Welding current can be adjusted with the wire feed
speed knob and then welding voltage changes auto-
matically in relation to adjustment. This provides e.g.
the possibility of torch adjustment of the welding
current and a special crater filling function, which can
be used when the function selection knob (pos. 3)
(page 41) is set a 4-times welding.
Wires feed units with synergy kit have a programme
selection knob (pos. 18) and a crater filling adjustment
knob (pos. 17).
Crater filling
In order to avoid crater formation at the end of a
welding seam this function reduces the welding
current immediately before ending the welding. The
function can be used when selecting 4-times welding
and thereafter by pressing the torch trigger at the end
of the welding. During crater filling the size of the
welding current is adjusted on the crater filling
adjustment knob (pos. 17) as a percentage of the
welding current during normal welding. This function
can only be effected when using synergy adjustment
of the welding machine.
Synergy adjustment according to table
A table with synergy welding programmes can be
seen in the cover to the wire drive roll. This table is
guidance on how to choose programme number, trim
value and inductor tap according to planned welding
process. The welding process is defined as selection
of material, wire diameter and shielding gas.
The table shows that programme number P9 (pro-
gramme selector pos. 18), trim value 22.5 (welding
voltage knob pos. 2) and inductor tap 3 matches
welding with Fe//Ø1.2mm//ArCO2 (80/20). Adjustment
is necessary before welding. Adjustment of the
welding current is only possible with the wire feed
speed knob (pos. 1) in this particular machine setting.
Please be aware of the fact that all adjustment
facilities in wire feed speed may not be weldable in
practice. This table gives a guidance on which wire
feed speed to be used for welding of different material
dimensions.
The welder is able to make his own synergy welding
programme. It is then necessary to use the following
process:
Adjust the programme selector to the following setting:
Wire diameter
0.8
1.0
1.2
1.6
1. Adjust the wire feed speed to the lowest value and
adjust the optimum trim value with the voltage
adjustment knob. The trim value is readable when
the torch trigger is not activated.
2. Adjust the wire feed speed to the highest value in
question and adjust the programme number to the
optimum value during welding (when the number
on the programme selector is increased the
voltage increases simultaneously during welding).
3. Repeat eventual point 3 and 4 in order to ensure
that it is the optimal programme.
4. The programme is finished, and the machine can
now be adjusted to the planned welding current
with the wire feed speed knob on the control panel
or the welding torch. Please note programme
number, trim value and process data for later use.
