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 [19].

"SEC" appears on the Left Display [11].

On the Right Display [14] the value in seconds flashes.

Set the crater time with the Right Control [17].

Confirm the setting of the crater time with the Right Button [19].

The Left Display [11] shows the value of the wire feed speed or
welding current, the Right Display [14] shows the voltage in volts
or the Trim value.

Set the value on the Left Display [11] by the left control [24].

Set the value on the Right Display [14] with the Right Control
[17].

Confirm the settings - press the Right Button [19].
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.
