OPERATING INSTRUCTIONS
Safety Precautions
WARNING
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts such as output terminals or internal wiring.
•When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.
•Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.
•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.
•Only qualified personnel should perform this installation.
Observe all additional Safety Guidelines detailed throughout this manual.

Mode Selection
Mode Select key ( behind “drop- door” cover) enables operator to choose mode of operation shown by the indicator lights. Pressing key causes mode lights to sequence (top to bottom) starting from the current indicated position.
Top Light - Indicates
1.Trigger closure energizes the solenoid valve, then the wire feeder and the power source after Preflow time (See Timer/ Crater Section).
2.Releasing the trigger turns off the wire feeder and power source and then the solenoid valve after Postflow time.
Middle Light - Indicates
The
a maximum current of 600 amps.
* Based on a 10 minute time period (6 minutes on, and 4 minutes off).
KEYPAD SETUP AND OPERATION
Power-Down Save
Power to the Synergic 7 is supplied and controlled from the power source. The Synergic 7 automatically senses the loss of power when the power source is turned off.
Procedure settings, including mode, crater speed, cold feed speed ,
Operation Keys
Cold Feed key energizes the wire
feeder but not the power source or solenoid valve. This cold feed speed is digitally displayed and is
COLD FEED adjustable (with “Arrow keys”) only while pressing the Cold Feed Key.
The last setting is held in memory for next Cold feeding.
Gas Purge key energizes the sole- noid valve but not the wire feeder or
GAS PURGE power source.
1.Trigger closure energizes the power source and wire feeder after the pre- flow time.
2.Trigger release enables
a)
b)
3.Closing the trigger a second time continues welding.
a)
b)
4.Releasing the trigger turns off wire feeder and power source and then gas solenoid after postflow time.
Bottom Light - Indicates Spot Weld Mode. Trigger closure energizes the solenoid valve, then wire feeder and the power source. The spot on timer starts when current flows. The wire feeder and power source then sole- noid valve are all turned off when the spot on timer times out even through the trigger is still closed.
