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.
•Turn OFF welding power source before installing 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.
Duty Cycle
The Synergic 7F models are rated at 60% duty cycle
*for 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 7F is supplied and controlled
from the power source . The Synergic 7F automatically senses the loss of power when the power source is turned off.

The 4-step modes function as follows:
1. Trigger closure energizes the power |
source and wirefeeder after the |
preflow time. |
2. Trigger release enables |

a) |
lock if weld current is flowing . |
Breaking weld arc stops wire feed |

3. Closing the trigger a second time |
continues welding. |
a) 4 - step with current interlock |
continues welding without changing |
the settings from step 2. |
b) 4 - step with crater fill continues |
welding but changes to the crater |

COLD FEED
GAS PURGE
Cold Feed key energizes the wire feeder but not the power source or solenoid valve. This cold feed speed is digitally displayed and is adjustable (with “Arrow keys”) only while pressing the Cold Feed Key. The last setting is held in memory for next Cold Inch feeding.
Gas Purge key energizes the solenoid valve but not the wire feeder or power source.

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 solenoid valve are all turned off when the spot on timer times out even through the trigger is still closed.
