The remote control expands the operational capabilities of the
main unit, making available a series of additional functions.
When connected, the remote control inhibits the control panel
of the main unit.
The foot pedal control can be connected to this remote control
to adjust the welding current.
Starting up
¾ Make sure that the welding machine is switched off before
connecting the remote control to the special socket.
¾ Connect the foot pedal, when necessary, to the socket (U)
L
As the welding generator is switched on, LED "Remote"
on its front panel will illuminate indicating that the control
has been properly connected.
L
The remote control will switch on with all the parameters
set at the values stored before the machine was switched
off.
Description of controls and signals
Once you have put the welding machine into operation, switch
it on and carry out the required adjustments (Fig. 1).
By means of the "SET" buttons you can choose the operating
options and select the welding parameters which can be
adjusted through encoder (S).
When an operating option is selected, the LED adjacent to its
corresponding symbol will illuminate.
When a welding parameter is selected, the LED adjacent to
its corresponding symbol will illuminate and it will possible to
adjust it through encoder (S).
The set value is shown on display (R)
The corresponding unit of measurement is shown by LED (O)
= Ampere; (P) = seconds; (Q) = %.
Unit of measurement and adjustment range are listed in table
1 for each parameter.
Selection of the welding process
MMA: Stick (coated) electrode welding.
TIG welding.
MMA Process: Adjustable parameters
Main welding current.
Adjusts the percent increase (0 – +200%) of the
value of the ARC FORCE current
Adjusts the percent increase (0 – +200%) of
the value of the initial peak current for an easier
arc striking
TIG Process: Available operating functions
The continuous main welding current is constantly
kept at the value set with (I).
The welding current is pulsed: it will alternatively
pulse between the Peak current (F2) and the
950526-01 21/02/16
Background current (F4). Adjustment of both
currents (F3) and (F1) is allowed.
TIG welding with LIFT ARC striking
TIG welding with high frequency arc striking
2T welding mode: press and keep the torch trigger
pressed to weld, the weld will stop as soon as the
button is released. Control of pre and post-gas
time, welding current ramps, etc. is possible.
Weld will stop automatically once the selected
time (H3) has expired
4T welding mode: the torch trigger will activate
different functions every time it is pressed and
released: pre and post-gas time, welding current
ramps, etc.
L
To fully understand how the torch trigger operates, please
read the "Operational welding examples" section.
When welding in this mode, a quick "press-and-
release" of the torch trigger will alternatively
switch the welding output from main current to
Low Current (H4).
TIG Process: Adjustable Parameters
Main welding current.
Pre-Gas Time, in seconds.
Post-Gas Time, in seconds.
L
When the encoder (S) is rotated fully anticlockwise
the display H will show "Aut", and the post gas time is
automatically adjusted by the internal microprocessor
between 5 - 20sec, according to the value of the welding
current and duration of the weld.
Time (in seconds) during which the initial current
after arc striking (H1) will increase up to the
selected main welding current (I).
Time (in seconds) during which the main welding
current will drop to the selected final value (G3)
once the torch trigger is released.
Initial value of the welding current at arc striking,
adjustable as a percentage of the main current.
Final value of the welding current, adjustable as
a percentage of the main current.
Duration, in seconds, of the spot time in 2T-SPOT
mode.
