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.

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 automatical- ly senses the loss of power when the power source is turned off.

Procedure settings, including mode, crater speed, cold feed speed , run-in speed, weld speed, timers and acceleration are automatically saved when power is removed. Arc Voltage setting is retained by the synergic power source. This feature does not require batteries and when power is restored it will automati- cally return all settings to the state they were in when power was removed. The power source may auto- matically overwrite any or all of these settings follow- ing power-up recall.

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 Inch feeding.

Gas Purge key energizes the sole- noid valve but not the wire feeder or

SPOT

Mode Selection

Mode Select key 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 2-Step (Standard) Trigger Mode.

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 4-Step (Lock) Trigger Mode. These models have selectable 4-step with crater fill or, as shipped, 4-step with current interlock. (See 4-step trigger mode selection for method of switching).

The 4-step modes function as follows:

1.Trigger closure energizes the power source and wirefeeder after the pre- flow time.

2.Trigger release enables 4-step lock, leaving the feeder and power source as in step 1.

a)4-step with current interlock will only lock if weld current is flowing. Breaking weld arc stops wire feed and power source output.

b)4-step with crater fill will lock without welding.

3.Closing the trigger a second time continues welding.

a)4-step with current interlock contin- ues welding without changing the settings from step 2.

b)4-step with crater fill continues weld- ing but changes to the crater set- tings.

4.Releasing the trigger turns off wirefeeder 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

GAS PURGE

power source.

the trigger is still closed.
