1. GENERAL DESCRIPTION. TECHNICAL FEATURES.
This equipment enable the arc-electric multiprocess welding :
Standard-arc MIG/MAG welding: Continuous, spot and interval. Manual and synergic adjustment programs.
Pulsed arc MIG/MAG welding: Continuous, spot and interval welding with synergic adjustment programs.
Bi-Pulsed MIG/MAG welding: with dual pulsed-arc feature which improve the welding bead aesthetic.
TIG DC welding with Lift-Arc striking. Pulsed TIG mode with general control of cycle parameters.
MMA welding: Rutilic, basic and stainless electrodes. MMA CEL Mode for special electrodes.
One of the main advantages of this equipment is that it has MIG/MAG processes with pulsed arc and dual pulsed arc,
enabling it to weld stainless steel and aluminium with synergic programs resulting in excellent welded seams. This makes
it possible in single-phase power networks with 16 A magneto-thermal protection. This equipment with PFC pre-inverter
stage allows high welding performance in a limited power electrical installation (3.7 KW) Its electrical efficiency level is
maximized obtaining the minimum network consumption.
The welding current is controlled by a microprocessor that enables the user to design the most suitable current form
for the welding job. For MIG/MAG and TIG procedures, this equipment is able to memorise up to 10 groups of welding
parameters (JOBS), offering more than 25 welding programs.

2. TRANSPORT AND INSTALLATION.
2.1. TRANSPORT AND PACKAGING
Knocks and sudden movements must be avoided when transporting the equipment. In any case, the packaging must
be protected from water.
HANDLE THE EQUIPMENT CAREFULLY, IT WILL LAST LONGER !
2.2. ELECTRICAL SUPPLY INSTALLATION.
The electrical installation of the equipment making up the system must be carried out by specialised personnel
according to the applicable standards.
The location must fulfil the following conditions:
-Place: Dry and ventilated. Far enough away from the welding area in order to prevent the dust caused by the
welding process from getting into the equipment. Never work in the rain.
-The distribution panel where the machine has to be connected must have the following elements, at least:

The connection to the mains is made by the input hose. IMPORTANT! Verify that the wire is connected to a plug with
an efficient earth tap.
If you have special equipment, with power supply voltage other than 230 V, you will find the data for defining the
necessary electrical installation on the equipment characteristics plate.
Any supply voltage that is outside the rated margin gives rise to the activation of the protection system, preventing the
welding operation.
GPS 2300 PFC BI-PULSE
If it is necessary to use a longer power supply
hose or a connection to an extension, keep in
mind the values of this table. These values are for
reference and are influenced by the state of the
conductors, connections and ambient
temperature.

ELECTRICAL INSTALLATIONS SHOULD ONLY BE HANDLED BY SPECIALISED PERSONNEL.
BEFORE STARTING THE EQUIPMENT, VERIFY THAT THE ELECTRODE-HOLDER CLAMP IS
SEPARATED FROM THE WELDING EARTH CLAMP.
DO NOT FORGET TO FIT THE EARTH CONNECTION INTO THE PLUG.
MAKE SURE THE MAINS VOLTAGE AGREES WITH THAT ESTABLISHED IN THE MACHINE.

3.4.1. MIG/MAG INSTALLATIONS.
Depending on whether the installation is cooled or not, we must set the equipment during the first start-up.
AUTOMATIC COOLING : Working mode with cooled torch.
The cooling only works in welding mode and will switch off automatically 2 minutes after carrying out the welding
process.
Automatic disconnection time (120s –Troff2: Not adjustable value).
COOLING “ON” : Working mode with cooled torch.
The cooling works permanently after the first welding process starts.
COOLING “OFF” : It enables to work with torches without water cooling.
The cooling is deactivated, the protection against lack of water pressure is disabled.

3.4.2. START-UP. PREVIOUS OPERATIONS TO MIG/MAG WELDING.
The system connection must be made depending on the welding process chosen, as indicated in the previous chapter.
Before you perform a final start-up of the system, you should carry out the following operations:
1st) Make sure the mains voltage is 230 V.
2nd) Change the polarity if it is necessary. Polarity to negative (for tubular wire without gas). See 3.4.1.3.
3er) If the material to be welded is aluminium, change the liner and the wire guide conduit for the graphite liner with
the torch totally stretched.

4th
Leave the wire conduit as
near the contact tip as
possible.
Screw the liner fastening
stop.
Secure the liner conduit
with the locknut and trim
the excess liner leaving it
at the right measurement.
Leave the liner as close
as possible to the
driving motor roller.
4th) Depending on the wire diameter, fit the groove of the suitable driving wheel to the work to be carried out.
5th) Choose suitable gas to wire type to be welded. In the case of carrying a mobile workstation, check that the gas
bottle is properly supported by the bottle holder system. Above all check that the safety chain is perfectly fastened.
6th) Install the pressure-reducing valve 6and connect gas hose 5 checking that there are no leakages, throughout the
whole circuit. Gas flow must be between 8-12 l/min.
7th) Connect the cooling unit to machine using the cable 13 (cooled system)
8th) Fit the wire reel into the support axle L.
9th) Slot the welding wire into the driving system. Do not force the wire pressure handle M, as if this is too tight, the
motor remains on overload and does not reach the maximum speed, and if the handle is too slack, the wire could slip.
(MIG/MAG).
10th) Once the wire has been fitted, we can then hook up the torch 7or 14 (cooled system) to Euro-connector.
11th) Respecting the colours blue and red (cooled system), connect the hoses 12 to torch 14 and cooling unit.

solenoid valve is activated
whilst depressed. The
solenoid valve activation is
prolonged for two seconds
after pressing.
The drive motor is
activated whilst
depressed.
14th) Switch on the cooling unit and check that coolant liquid is within the specified levels (cooled system).
15th) Select in the Control Panel within the cooling process between the options Switch-on or Automatic “REF→ON or
AUT” (cooled system).
