Set Synergic Pulsed MIG welding process using P3 push button.
Synergic Pulsed MIG welding is a high quality welding process that produces very little spatter. This process works well on thin metals such as stainless steel and alu- minum.
In Synergic Pulsed MIG mode, the opera- tor 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 pro- cess automatically sets appropriate weld voltage. Synergic welding also sets many secondary welding parameters automati- cally 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). Set wire feed speed in meters/min (M).
Select wire type using P4 push button. Select wire diameter using P5 push button. Select trigger mode using P6 push button. Set desired wire feed speed using E2.

Setting Trim
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.
.Trim setting may vary by a greater
amount depending on welding posi- tion, parameter settings, and quality of wire.
Setting Inductance
Press P7 until L17 LED illuminates.
L17 ON selects Inductance. Default setting is 100% (range is 1% to 200%). D1 and D2 return to main display after several sec- onds.
.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.
Setting Thickness
Press P7 until L18 LED illuminates.
L18 ON selects material thickness. D2 shows thickness in mm for the welding pro- cess.
Use E2 to change material thickness val- ue. This value is stored in process memory. Material thickness is a reference value only, not a mandatory setting. D1 and D2 return to main display when P7 is pressed again.
Setting Gas
Press P7 until L19 LED illuminates.
L19 ON selects type of gas. D1 will show GAS and D2 shows gas abbreviation as follows:
8218 = 82% Ar, 18% CO2 Ar = 100% Argon
CO2 = 100% CO2
9802 = 98% Ar, 2%CO2
Use E2 to change gas type. This setting is stored in process memory.
LED will turn off after several seconds and D1 and D2 will return to main display.
.D1 and D2 will show NO PROG or a
selection will not be allowed when there is no program for the process, material, wire diameter, and shielding gas combination.
