MIG, GMAW, Fluxcore Wire (FCAW) Synergic Welding

• Select MIG Synergy (2T or 4T) Welding function thru the Selector Switch (6) on the front
panel. The 2-Step / 4-Step change the function of the gun's trigger. 2-Step trigger turns
welding arc ON and OFF each time the trigger is pressed. Welding current is ON when
the torch trigger is pressed. 4-Step mode permits the operator to weld with the torch trigger
released. To stop welding press and release the torch trigger. 4-Step mode helps the operator
make long welds.
• MIG Synergy functions permits the operator to move to different materials thickness to be
welded simply adjusting the Left Knob (8). The correct voltage will be set automatically by the
machine's software. In order to permit the software to set the correct voltage the operator is
asked to set the "starting welding parameter" as suggested on the setting chart. In fact a wire
speed value and voltage value have to be set in order to activate the synergy mode.
• Switch the unit ON thru the ON/OFF switch (14) on the back side of the unit.
• Press the torch trigger to load the wire and check that the gas is flowing from the welding
torch.
• Set the "starting welding parameters":
1. Wire feed speed: A) If "Local (20)" is selected use Left Knob (8) to adjust the wire speed
from 1 to 80 (maximum speed). If "Remote (20)" is selected use the potentiometer of the
Spool Gun torch to adjust wire speed.
2. Arc length: use the Right Knob to adjust arc length value from 0 to 80.
3. Once both parameters are set, the Synergic Mode allows the operator to weld different
thickness of the same material by simply adjusting the Left Knob (8).
• Bring the torch close to the work piece and press the trigger.
1. Wire feeder Slope-Up Time (Min. to Max. speed transition time), adjustable with the
potentiometer located inside the access panel (17).
2. At the end of the the Slope-Up Time, the wire feed speed reaches the value adjusted with
the Left knob (8).
• To stop welding, release the trigger. The arc stays ON accordingly to the set B.B.T. (Burn
back time). B.B.T. is the amount of time that the weld output continues after the wire stops
feeding. It prevents the wire from sticking in the puddle and prepares the end of the wire for
the following arc start.
