L7
P1 P2 P3
Set Synergic MIG welding process on the power source. L7 is ON.
In Synergic MIG mode, the operator may need to adjust welding data (wire type, wire diameter, and gas type) and only one weld parameter. Generally, wire feed speed is adjusted and the synergic process auto- matically sets appropriate weld voltage. Synergic welding also sets many secon- dary welding parameters automatically for improved weld quality.
Trim parameter appears on D1 and D2:
D1 value is default trim setting of 0.0 T (range is −5.0 T to 5.0 T).
D2 value is default wire feed speed setting of 5.0 m/min (minimum (MIN), maximum (MAX), or default (DEF) values are arbi- trary based on set welding data). Use P2 and E2 to change this display to amperes or to the thickness of the material.
While Setting Parameters:
-L2 ON means that D1 shows Trim value.
-L3 ON means that D2 shows the wire speed in meter/min or inch/min.
-L4 ON means that D2 shows the set weld- ing current in amperes.
-L5 ON means that D2 shows the thick- ness of material to weld.
While Welding:
-D1 shows the measured welding voltage in Volts. L1 is ON.
-D2 shows the measured welding current in amperes. L4 is ON.
Set wire speed, welding current or material thickness and welding voltage with E2 and E1.
Select trigger mode using P1 pushbutton (see Section
If necessary, use P2 to adjust the welding parameters.

D1 value is default trim setting of 0.0 T (range is −5.0 T to 5.0 T).
Trim is an arbitrary value related to MIG arc length. Higher values produce a longer and hotter arc. Lower values produce a shorter and cooler arc. Recommended value for trim is default setting or near 0.0T. L2 is On.
Synergic MIG Welding Advanced Set- tings
To change all values list, unit must be SET- UP FULL. To set unit to SETUP FULL, pro- ceed as follows:
Press P2 to enter SET UP menu.
Select SETUP FULL on D1 and D2 (see Section
Setting Main Welding Regulations
Enter SET UP and select rEG on D1 with E1.
D2 shows the main parameter and E2 changes it.
When D2 shows SPE (wire speed) the main regulation is the speed of the welding wire. L3 is ON.
When D2 shows A (ampere) the main regu- lation is the welding current in Amperes. L4 is ON.
When D2 shows thc (thickness) the main regulation is the material thickness in mm. L5 is ON.
.The modification to the main welding
regulation is confirmed when exiting the Set Up Menu.
.The measured welding current can be
different from the set value. This differ- ence can be greater if there are changes on the default parameters and if the welding conditions are not conventional. Setting amperage must be considered a reference.
.Material thickness setting is a refer- ence value only.
Setting Inductance
Press P2 to enter SET UP menu.
Use E1 to select on D1 ind. D2 shows 100.
If necessary, use E2 to adjust inductance value (range is 1% to 200%).
.Higher inductance setting produces a
softer weld puddle and less spatter, but arc starts may be more difficult. Lower inductance setting produces a stiffer weld puddle and more spatter, but arc starts may be easier.

Use E1 to change D1 to 3L.1
D2 value is the default setting of 130% (range is 20% to 200%).
Use E2 to change D2 value. Use E1 to change D1 to 3L.2
D2 value is the default setting of 80% (range is 20% to 200%).
Use E2 to change D2 value. Use E1 to change D1 to 3L.r
D2 value is the default setting of 0.5 s (range is 0.1 s to 0.5 s).
This value is the ramp time in seconds to reach the following level wire speed.
