Preflow Time – time that shielding gas flows after the torch
trigger was pressed before prior to wire feeding.

Regulation range: from 0 seconds (OFF) to 25
seconds.

Default settings for non-synergic mode: 0,2s.

Default settings for synergic mode: AUTO mode.
Postflow Time – time that shielding gas flows after stop
welding.

Regulation range: from 0 seconds (OFF) to 25
seconds.

Default settings for non-synergic mode: 0,5s.

Default settings for synergic mode: AUTO mode.
Spot Timer – adjusts the time welding will continue even if
the trigger is still pulled. This option has no effect in 4-Step
Trigger Mode.

Regulation range: from 0 second (OFF) to 120
seconds.

Default settings: OFF.
Note: Spot Timer has no effect in 4-Step Trigger Mode.
Crater Procedure controls the WFS (or value in ampere)
and Volts (or Trim) for a specified time at the end of the
welding after the trigger was released. During the crater
time, the machine will ramp up or down from the Weld
Procedure to the Crater Procedure.

Adjust time range: from 0 seconds (OFF) to 10
seconds.

Default settings: OFF.
Crater parameters:

Crater time

Wire feed speed or welding current.

Voltage in volts or Trim value.
To set a crater for a selected process:

Press the right button [25].

"SEC" appears on the left display [17].

On the right display [20] the value in seconds flashes.

Set the crater time with the right control [23].

Confirm the setting of the crater time with the right
button [25].

The left display [17] shows the value of the wire feed
speed or welding current, the right display [20] shows
the voltage in volts or the Trim value.

Set the value on the left display [17] by the left control
[30].

Set the value on the right display [20] with the right
control [23].

Confirm the settings - press the right button [25].
Polarization – Used for configuration of the work and
electrode sense leads

"Positive" (default) = Most GMAW welding procedures
use Electrode Positive welding.

"Negative" = Most GTAW and some inner shield
procedures use Electrode Negative welding.
Cooler – option is available when cooler is connected.
This function allows following cooler modes:

FILL – Filling.

AUTO – Automatic mode.

On – Cooler on in the continuous mode.

Off – Cooler off.
Refer cooler instruction manual for more details.
