2- Manual wire jog button. This jogs the wire forward in the torch sheath without
having to touch the torch button; this is a momentary action and the speed is set
Pressing the button also causes the light to switch on in the feeder compartment
(version with separate wire feeder unit only).
solenoid valve remains enabled for 10 seconds or until it is pressed again.
4- Multi-function button.
-
If pressed, it allows access to preset machine programs.
-
If pressed, for at least 3 seconds it allows you to:
- save a job on the machine internal memory.
- load a previously saved job.
5- Multi-function knob.
Rotation enables:
- wire speed feed adjustment in
- welding power adjustment in
- welding current adjustment in TIG mode (
- welding current adjustment in MMA mode (
- if pressed for at least 3 seconds, it enables access to various setting menus of
the machine.
6- Multi-function knob.
Rotation enables:
- adjustment of the welding seam (welding voltage) in
- adjustment of the welding seam (arc length) in

Choose the place where the welding machine is to be installed so that there are no
obstructions to the cooling air inlets and outlets; at the same time make sure that
conductive dust, corrosive vapours, humidity etc. cannot be drawn into the machine.
Leave at least 250 mm of free space all around the welding machine.
- Before making any electrical connection, check the rating plate data on the welding
machine to make sure they correspond to the voltage and frequency of the available
power supply where the machine is to be installed.
- The welding machine must be connected only and exclusively to a power supply with
the neutral conductor connected to earth.
- To guarantee protection against indirect contact use the following types of residual
current devices:
) for single-phase machines.
- Type A (
- Type B (
) for 3-phase machines.
- In order to satisfy the requirements of the EN 61000-3-11 (Flicker) standard we
recommend connecting the welding machine to the interface points of the main
power supply that have an impedance of less than Zmax = 0.10 ohm.
- The IEC/EN 61000-3-12 Standard does not apply to the welding machine.
If the welding machine is connected to an electrical grid, the installer or user must
make sure that the machine can indeed be connected (if necessary, consult the
company that manages the electrical grid).
earth terminal should be connected to the earth conductor (yellow-green) of the power
supply line.
Table
shows the recommended delayed fuse sizes in amps, chosen according
to the max. nominal current supplied by the welding machine, and the nominal voltage
of the main power supply.
Table 1 (TAB. 1) gives the recommended values for welding cables (in mm
to the maximum energy supplied by the welding machine.
In addition:
- Fully rotate the welding cable connectors in the quick couplings (if present), to
guarantee perfect electric contact; if this is not the case the connectors will overheat
- Use the shortest welding cables possible.
- Do not use metal structures that are not part of the workpiece to replace the welding
current return cable; this can endanger safety and give unsatisfactory welding
results.
- Gas bottle that can be loaded onto the supporting surface of the trolley: max. 60 kg.
- When using Argon gas or an Argon/CO
the gas bottle valve, placing the relative pressure reducing valve supplied as an
accessory.
- Connect the gas input hose to the pressure reducing valve and tighten the strip.
- Loosen the adjustment ring nut of the pressure reducing valve before opening the
gas bottle valve.
(*) Accessory to be purchased separately if not supplied with the product.
Connect the cable to the piece to be welded or the metal bench on which the workpiece
is placed, as close as possible to the joint being worked.
Insert the torch (B-6) into the dedicated connector (B-2), fully tightening the locking
nozzle and the contact pipe, to make exiting easier.
Connect the external cooling pipes to the relative couplings paying attention to the
instructions below:
: COOLANT DELIVERY (Cold - blue coupling element);
: COOLANT RETURN (Hot - red coupling element).
- Screw the pressure reducer onto the cylinder gas valve, if necessary, inserting the
