SYNERGIC AND BASIC MIG OPERATION
Synergic vs. Manual Setup and Operation
Synergic MIG operation:
The Synergic function of the MIG (255HF) component allows the user to only need to use the wire feed speed control to
make the unit operate. The welder is programmed to automatically adjust the voltage based on the users input of wire
diameter and filler metal type when the wire speed is increased or decreased by turning the wire speed adjustment knob.
While in the Synergic mode the user can make manual adjustment to “fine tune” the voltage if he chooses by turning the
voltage up or down after adjusting the wire feed speed. If the wire speed is re-adjusted after manual adjustment to voltage
is made, the unit defaults to the synergic mode again and voltage is once again adjusted automatically.
The welder may be used in full manual mode with independent control of the wire feed speed by simply selecting STD on
the wire diameter selector. Settings will not be saved when the unit cycles off and back on and will default to factory
settings. If stepping away briefly it is best to keep the unit on, or the settings will not remember the last settings if it is
turned off.
How to setup the Synergic and Manual functions:
1. Turn unit on. Wait for it to go through the power up cycle.
2. Select the MIG icon with the Process Selector button. Selecting STD defaults unit to full manual mode.
3. Select the wire diameter of the wire being used.
4. Select the filler wire type. Steel, Al= Aluminum, SS= Stainless Steel.
5. Select 2T or 4T function. 2T is simply press and hold the torch trigger to start and activate the torch.
6. 4T requires the trigger to be pressed to start the arc. Once arc is started the trigger should be released to continue
weld. The trigger should once again be pressed, held briefly and then released to terminate the arc when ready.
7. If used in the manual mode (STD), select the appropriate wire feed speed and voltage to match wire type and
size. Listen for a steady frying sound while welding to give you a key as to when it is adjusted properly.
If used while in Synergic mode (SYN), select the desired wire speed and the voltage will adjust automatically. If a
minor voltage adjustment is felt like it is needed while in the synergic mode, simply turn the volt-age knob to
increase the voltage from the automatically selected setting. If more wire feed speed is desired, the unit will
default back to the automatic setting as the wire feed speed is increased or decreased. However, manual control
can once again be asserted over the automatic setting by simply turning the voltage knob once again.
8. Use the MIG inductance control to select the desired arc qualities and adjust the arc qualities, whether a stiff,
penetrating arc with a narrow bead profile and slightly more spatter, or a wider more fluid puddle that easily wets
in with low amounts of spatter.
Overhead welding usually requires a stiffer penetrating arc. Flat welding will accept a wider more fluid puddle.
