L1 span: When the two level mode is active the
duration of the first power level can be set.
L2 span: When the two level mode is active the
duration of the second power level can be set.
L2 amplitude: When the two level mode is active
the second power level (L2) can be set with
respect to the set power (level L1).
2t-4t-4bilevel: This function adjusts the 2 step or
4 step settings.
2t: In 2 step mode, the machine will weld for as
long as the torch trigger is pressed down.
4t: : In 4 step mode, press the trigger once to
start the torch, press again to stop the torch.
4Bi: In 4 step Bi- Level mode, press the trigger
once to start the torch, successively, briefly
pressing the trigger (for less than 1s) will cause
the set welding current to pass to second level
and vice versa. Prolonged pressure on the torch
trigger will halt the welding process.
2nd level: This option is for setting the values the
wire speed, corresponding to the second power
level, which is active when the values of the
2t-4t-4bi-level is set to 4bi.
Initial/final current: it allows to switch up (ON) or
down (OFF) mode with starting/final current.
Initial current: allows setting the value at which
the welding current is brought to immediately
after the striking of the electric arc
Initial time: allows setting the time of the current
established by the Initial Current parameter. In
4t/4bi mode this time is irrelevant and the initial
current is kept for as long as the torch button is
held down.
Ramp ls- > l1: allows setting the duration of the
upslope of the welding current.
Ramp l1- > lf: allows setting the duration of the
downslope of the welding current
Final current: allows setting the value at which
the welding current is brought to on completion
of the downslope
Final time: allows setting the time of the current
established by the Final Current parameter. In
4t/4bi mode, this time is irrelevant and the final
current is kept for as long as the torch button is
held down.
Spot welding: This sets the maximum welding
duration (when different to 0), in seconds.
Pause: This sets the duration of the pauses
(when different to 0), between two successive
tacks.
Pre gas time: This sets the gas supply time
before the welding current is supplied.
Post gas time: This sets the gas supply time after
the welding current supply ends. 13
Burnback: This adjusts the length of the wire in
the tip of the torch, when the welding process
comes to an end. Soft-start: this adjusts the
contact speed of the wire, to obtain a soft weld
spark; the higher the values the lower the contact
speed. Hot-start: This sets the weld ignition
current, in order to achieve a softer weld spark;
this is generally used with the soft-start option.
Water pump: When present, this turns the water
system ON or OFF.

5. MIG WELDING CONECTOR
The connector for the welding cables comes with
a quick connect system that uses appropriate
connectors.
5.1. MIG TORCH We would advise you to carry
out regular controls on the condition of the
welding torch;in particular, always check the
nozzle the wire feeder tip and the internal liner of
the torch. These parts must be kept well-cleaned
and intact. If the wire stops threading correctly.
replace the liner. N.B. Each wire and diameter
corresponds to an appropriate wire feeder tip
and liner. Always make sure you are using the
correct type.
5.2 CONNECTOR FOR MIG WELDING with a
traditional torch
1) Connect the earth cable to the appropriate
‘-‘ socket on the front of the device (12 of Fig
1).Insert the connector by lining up the key with
the groove and turn in a clockwise direction until
it stops. Do not fasten too tightly!
2) Connect the torch to the appropriate socket
in the front of the device (16 di Fig 1),turning the
connector in a clockwise direction until it stops.
Do not fasten too tightly!
Warning: the machine is provided with sockets
