1INTRODUCTION
IMPORT NT!
This handbook must be consigned to the user prior to
installation and commissioning of the unit.
Read the "General prescriptions for use" handbook supplied
separately from this handbook before installing and
commissioning the unit.
The meaning of the symbols in this manual and the associated
precautionary information are given in the "General
prescriptions for use”.
If the "General prescriptions for use" are not present, it is
mandatory to reque
st a replacement copy from the manufacturer
or from your dealer.
Retain these documents for future consultation.

D NGER!
This pictogram warns of danger of death or serious injury.
This symbol identifies an action that occurs automatically as
a
result of a previous action.
This symbol identifies additional information or a reference to a
different section of the manual containing the associated

INTRODUCTION
Discovery 150TP-VRD is an advanced inverter power source
characterized by a robust and reliable industrial construction.
It is recommended for MMA welding and TIG DC applications
providing excellent arc characteristics.
Discovery 150TP-VRD is ideal for operations on site like basic
maintenance and building construction.
A built-in Total Protection Device saves the inverter components from
overvoltage and makes the unit suitable for use with unstable power
supply and motor-generators.
Factory optimized Hot Start, Arc Force and Anti Sticking allow an easy
and excellent quality welding using electrodes up to 3.25 mm
diameter.
In TIG DC, Pulse selection is included, making Discovery 150TP-VRD
unique in its range.
ift Start function guarantees arc ignition without damaging the
tungsten electrode.

5.
Connect the torch plug to the weldi
ng socket on the basis of the
polarity required by the type of electrode in question.
6.
Connect the plug of the ground clamp to the welding socket on the
basis of the polarity required.
7.
Connect the earth clamp to the workpiece being processed.
8.
Set the welding power source ON/OFF switch to “I” (unit

9.
Select the following welding mode on the user interface: DC TIG
This model of welding machine has not been provided either with
the control for gas flow (solenoid valve) or with the torch button.
The system is ready to start welding.
LIFT- RC WELDING
1.
Open the torch valve to let the gas out.
2.
Touch the workpiece with the torch electrode.
3.
Slowly lift the torch to strike the arc.
The WE DING CURRENT reaches the preset
value.
4.
Quickly move the torch clear of the workpiece to extinguish the
welding arc.
5.
Close the torch valve to interrupt the gas flow.

DESCRIPTION
1
Overheating alarm
Indicates tripping of the welding power source thermal protection.
eave the unit running so that the overheated components cool as rapidly as possible.
When the unit has cooled, the welding power source will reset automatically.
-Make sure that the power required by the welding process is lower than the maximum rated power output.
-Check that the operating conditions are in compliance with the welding power source data plate specifications.
-Check for the presence of adequate air circulation around the welding power source.
2
This ED illuminates to confirm the presence of power on the output sockets.
3
ctive VRD signal
When lit this shows that the Voltage Reducing Device is active, reducing the voltage across the welding sockets.
This will happen within 2 seconds after the welding arc is broken to protect the welder from electric shock.
Full arc striking voltage will automatically be re-established when the welding circuit is re-established by touching the
electrode to the work-piece.
