2. Opening the gun trigger ends the welding
sequence (burnback, postflow, etc.).
With Hot/Soft Start "ON":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in) and changes the
wire feed speed and the Volts/Trim to the
Hot/Soft Start values. After the Hot/Soft Start
time, the welding sequence continues and
changes the wire feed speed and the Volts/Trim
to Welding values.
2. Opening the gun trigger ends the welding
sequence (burnback, postflow, etc.).
With Crater Fill "ON":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger will changes the wire feed
speed and the Volts/Trim to the Crater values,
and the downslope will continue during the
Crater time.
4 Step Logic:
With Hot/Soft Start & Crater Fill "OFF":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in, etc.).
2. Opening the trigger allows the wire to continue
feeding before or after the welding arc is
established. If the arc goes out the wire
continues feeding.
3. Closing the trigger again cancels the interlock
and the wire to continues feeding.
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).
With Hot/Soft Start "ON":
1. Closing the gun trigger initiates the welding
sequence (preflow, run in) and changes the
wire feed speed and the Volts/Trim to the
Hot/Soft Start values.
2. Opening the trigger continue in the welding
sequence and changes the wire feed speed
and the Volts/Trim to Welding values. The wire
continues feeding while the welding arc is
established. If the arc goes out the wire
continues feeding.
3. Closing the trigger again cancels the interlock
and the wire to continues feeding.
4. Opening the trigger again ends the welding
sequence (burnback, postflow, etc.).

M2. Water / air cooled torch selection switch
(as standard on water cooled models)
Set this switch according to the torch model (air cooled
or water cooled) being used.
M3. Cold Inch control and Gas Purge control
This is an up/down center-off momentary toggle switch.
When held in the down position, the Wire Drive will feed
wire, but neither the power source nor the gas solenoid
will be energized. When cold feeding, the feed speed
can be adjusted by rotating the WFS encoder knob on
the Control Box. Adjusting the cold feed will not affect
the run in or welding wire feed speed. When the cold
feed switch is released, the cold feed value is saved.
When this switch is held in the up position, the gas
solenoid valve is energized, but neither the power
source nor the drive motor will be energized.
Control Panels
Control/Display Front Panel.
This panel consists of adjustment knobs, digital displays
and a series of indicator lights (LEDs). There are two
knobs; each has a 4 digit LED display and a pair of
LEDs associated with it. Knobs and displays have dual
functions; the LEDs indicate which function at any given
time.
The left knob/display is labeled WFS / AMPS (wire feed
speed/amps).
•
In non-synergic modes, the WFS control changes
the wire feed speed according to the desired
procedure.
•
In synergic welding modes (synergic CV, pulse
GMAW) WFS is the dominant control parameter,
controlling all other variables.
The power source then uses the WFS setting to adjust
its output characteristics (output voltage, output current)
according to preprogrammed settings contained in the
power source.
A LED lights to inform the user which function (WFS or
amps) is active.
The right knob/display is labeled VOLTS / TRIM. In
constant voltage modes (synergic CV, standard CV) the
control adjusts the welding voltage. In pulse synergic
welding modes (pulse GMAW only) the user can change
the Trim setting to adjust the arc length. It is adjustable
from 0.50 to 1.50. A Trim setting of 1.00 means than no
adjustments will be made to the preset arc lengths, and
is optimum for most conditions. An LED lights to inform
the user which function (volts or trim) is active.
Both displays indicate preset values, according to the
weld mode selected, when not welding. Once welding
begins, they switch to displaying actual values. At that
time, the indicator LEDs will flash to signify actual values
are being displayed. The displays hold the actual values
