wire
Voltage control
MIG/MAG: local control of voltage
MMA welding: no operation
Filler wire material and diameter selection
Filler wire type selection
Filler wire diameter selection
On the basis of the selections, the equipment generates optimal welding
characteristics for the wire in question.
Compensating cable length
With this function the voltage losses with long interconnecting cables and
different welding guns can be compensated. Cable compensation is adjusted as follows:
If interconnecting cables are not used, set cable compensation at position zero.
If the zero position does not operate wanted, check the adjustment as follows:
1. Select arc length at = CAL, which corresponds to normal arc length.
2. Weld at required power level.
3. Select a suitable arc length with the potentiometer.
4. Check adjustment range of arc length by adjusting arc length -9...0...9
5. When needed repeat the procedure.
Cable compensation is adjusted for each cable and MIG welding gun combination only once.
Control of welding dynamics
MIG and MMA welding dynamics are adjusted with the same potentiometer.
When you adjust welding dynamics the adjustment value -9...0...9 is shown in
display V, which otherwise shows set value/welding voltage. Value of dynamics
is shown in display still for approx. 3 s after stopping the adjustments.
Control of MIG/MAG welding dynamics
With control of MIG/MAG welding dynamics you can influence on how stable the arc is and how
much spatter there is. With this control you can also optimize the welding result for wire type and
shielding gas mixture you are using.
-9...-1 Softer arc. Object: minimizing spatter
0 Recommendable basic setting for all wires
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit and welding of
steel with 100 % CO² shielding gas (settings 7...9).
Control of SYNERGIC MIG welding dynamics
In SYNERGIC MIG the control of welding dynamics is optimized for wire type you are using.
With this control you can influence on stability of arc and how much spatter there is.
-9...-1 Softer arc. Object: Minimizing spatter
0 Recommendable basic setting
1...9 Harder arc. Object: e.g. maximizing stability of the arc on short circuit
NOTE! The control range for MIG welding dynamics -9...0...9 is a relative range according to wire
and is different from control range -9...0...9 for dynamics of normal MIG/MAG welding.
