immediately.

1- TRG

Choice between

4- stages

3 levels,

the selection

and

with the selection key

, without entering the

service functions.

the machine begins welding when the welding torch

trigger is pressed, and stops when released.

to begin

welding press and release the welding torch trigger; to
interrupt, you must press and release it again.

this pro-

cedure is active in the synergic processes. Specially well
suited to weld aluminum.
3 currents are available that can be used in welding by
means of the welding torch start button. The current and
the slope values are set as follows:

starting current (Hot Start). With the possibility of

adjusting from 1 to 200% of the welding current, a value
adjusted using the knob

Slo

slope. Possibility of adjusting from 1 to 10 seconds.

Defines the connection time between the first current

with the welding current and the second current with the
third current

CrC

( crater filler current), a value set by

means of knob

AN.

CrC -

«Crater filler» current. With the possibility of adjust-

ing from 1 to 200% of the welding current, a value adjust-
ed using the knob

AN.

Welding starts at the welding torch button pressure, the
named pressure will be the starting pressure

This current is kept as long as the welding torch button is
held down; when the welding torch trigger is released the
first current connects to the welding current, set by
means of knob

, and is kept as long as the welding

torch button is held down. When the welding torch trig-
ger is pressed again the welding current connects to the
third current

CrC

. and is kept as long as the welding

torch trigger is held down. When the welding torch trigger
is released welding stops.

2- SP (spot-welding).

Off/ON activates and disables the spot function.
The spot welding time

tSP

is set from 0.3 to 5 seconds.

The interval between two spots

tIN

is set from 0,3 to 5

seconds.
This function is è blocked when function

is activated.

3- HSA (Automatic Hot Start).

This function is blocked when function

is activated

and works only with the synergic processes.
Once the function has been enabled using the

knob ,

the operator may adjust the level of the starting current

(Hot Start), with the possibility of adjusting from 1 to

200% of the welding current, a value adjusted using the
knob

The duration

tHS

(default 130%) of this current may also

be adjusted from 0.1 to 10 seconds.) (default 0,5 sec.).
The switching time

Slo

between the

current and the

welding current may also be adjusted from 0.1 to 10 sec-
onds.(default 0.5 seconds).

4- CrA (final crater filler).

This function may be selected by means of key

and is

working during welding

and also in combination

with function HSA, if so requested.

After activating function

«On»

by means of knob

rotate knob

to display the abbreviations:

Slo

= Fitting time between the welding current and the

crater filling time. Default 0.5 sec.
Range 0.1 – 10 seconds.

CrC

= crater filling time expressed as a percentage of the

welding wire speed. Default 60%. Range from 10 to
200%.

TCr

= duration of the filling current time. Default 0.5 sec.

Range 0.1 – 10 seconds.

5- PrF (Pre-gas).

The adjustment may range from 0 to 3 seconds.

6- Pof (post-gas).

The adjustment may range from 0 to 30 seconds.

7- Acc (soft-start ).

The adjustment may range from 0 to 100%.
It is the wire speed, expressed as a percentage of the
speed set for the welding, before the wire touches the
workpiece.
This adjustment is important in order to always achieve
good starts.
Manufacturer setting «Au»: automatic.

The value can be changed using the knob AN

. If, once

changed, you wish to return to the original settings,
press the key

until the abbreviation

«Au»

reappears on

the display

8- BB (Burn-back).

The adjustment may range from 4 to 250ms. Serves to
adjust the length of the wire leaving the contact tip after
welding. The higher the number, the more the wire burns.
Manufacturer setting «

» automatic.

If, once changed, you wish to return to the original set-
tings, press the key

until the abbreviation «

» reap-

pears on the display

9- L (impedance).

The adjustment may range from

-9.9

+9,9

. Zero is the

number set by the manufacturer:if the number is negative,
the impedance decreases and the arc becomes harder; if
increased, it becomes softer.

10- dP ( Double pulse, optional )

This type of welding varies the current intensity between
two levels and may be included in all synergic processes.
Before setting, it is necessary to make a short bead to
determine the speed closest to the type of welding that
you will be doing. This determines the reference speed.
To activate the function proceed as follows:

A)-

Activate the function by turning knob

until the

abbreviation

reappears on the display

B)-

Turn knob
