Parameters and functions description:
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
(factory default is set at Auto mode).
Postflow Time – time that shielding gas flows
after the welding sopped.
Regulation range: from 0 seconds (OFF) to
25 seconds (factory default is set at Auto mode).
Burnback Time - amount of time that the
welding is continue after the wire stops
feeding. It prevents the wire from sticking in
the puddle and prepares the end of the wire for the next
arc start
Regulation range: from OFF to 0.25 seconds (factory
default is set at Auto mode).
Spot Welding Settings – sets the total
welding time even if the torch trigger is still
pressed. This function does not work in 4-Step
Trigger Mode.
Regulation range: from 0 second (OFF) to 120 seconds
(factory default is OFF).
WARNING
Spot Timer has no effect in 4-Step Trigger Mode.
Run-in WFS – sets the wire feed speed from
the time the torch trigger is pressed until an
arc is established.
Regulation range: from minimum to 150 in/min (factory
default is set at Auto mode).
Start Procedure – controls the WFS and
Volts (or Trim) for a specified time at the
beginning of welding. During the start time, the
machine will ramp up or down from the Start Procedure to
the preset Welding Procedure.
Adjust time range: from 0 seconds (OFF) to 10 seconds.
Crater Procedure – controls the WFS (or
value in ampere units) 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.
A/B Procedure –
procedure change. The sequence changes
may occur between:
Two different welding programs.
Different settings for the same program.
Recall from the User Memory - recall the
stored programs from the user Memory. To
recall the Welding Program from the User
Memory:
Note: Before using, the Welding Program had to be
assigned to the user memory
Add the "Load" icon to the Welding Parameters Bar.
Use the right knob [33] to highlight the "Load" memory
icon.
Press the right knob [33] to confirm – the "Load" memory
menu is shown on the display.
Use the right knob [33] to highlight the Memory number
from which Welding Program will be recall.
Confirm the selection – press the right button [33].
Save to the User Memory - Store the welding
programs with their parameters to one of the
fifty user memories. To save in memory:
Add icon „Save to the User Memory" to Welding
Parameters Bar.
Use the right knob [33] to highlight the icon „Save to the
User Memory".
