The screen displays the welding current in Amperes
and the welding voltage in Volts.

To carry out the gas test refer to the relevant
paragraph in "MIG PROCESS".
C
Start mode.
Mode 2T and 4T.
For the operation instructions refer to the relevant para-
graphs in "MIG PROCESS".
Mode 3L.
3 currents are available that can be used in welding by
means of the welding torch start key. The current and the
connection time values are set as follows:
Start Current, adjustable from 10 to 200% of set welding
current.
Slope time, possibility of adjusting from 0.1 to 10 seconds.
Defines the connection time between Start current and
welding current and between welding current and crater
filling current or crater filling at the welding end
Start Current, adjustable from 10 to 200% of set welding
current.
Welding starts at the torch trigger pressure. The recalled
current will be the start current. This current is kept as
long as the welding torch trigger is held down; when the
welding torch trigger is released this current connects to
the welding current, which is kept till the welding torch
trigger is pressed again.
When the torch trigger is pressed again, the welding cur-
rent will connect to the Crater filling current and it will
be maintained until the torch trigger is released.

Pulsed (Can be used in Mode 2T-4T and 3L).
Pulsed TIG welding.
In this type of welding, current intensity varies between two
levels; this variation occurs at a given frequency.

Impulse
This item allows the setting of the lower current between
the two currents that are required for this welding pro-
cess; the percentage of this current is displayed related
to the main current.
This impulse can be adjusted from 1% al 100% of the
main current.
Frequency
It is the pulse frequency.
This value can be adjusted from 0.1Hz to 500Hz.
Duty cycle
This is the duration of the highest current, expressed in
percentage, compared to frequency time.
This value can be adjusted from 10% to 90%.
D
Current slope down.
0.5s
Adjustable from 0 to +10 seconds.
E
Post gas.
10.0s
Adjustable from 0 to 25 seconds.
