THE ART OF WELDING
P6 HW
6-100 PN-0110008 Rev. 12
Recommendations1. 3.
Risk of electric shocks.
The electrical components include the electrode,
the welding circuit, the input circuit and the inter-
nal circuits, the welding wire and the metal parts in
contact with it, the wire spool and the housing for
the welding wire feed rollers. The slightest contact
with these parts may cause an electric shock or even
electrocution when the machine is switched on.
Factors increasing the risk of electric shock: Moisture
in the immediate area, working on an electrically-con-
ductive surface, inadequate earthing, poor mainte-
nance of the equipment, unsafe working methods.
Preventing risks:
Avoid any contact with live wire spools.•
In the case of water-cooled torches, inspect the•
torch at regular intervals in order to identify any
leaks; take care to prevent condensation.
Do not coil the cables around your body.•
Before replacing the electrode, ensure that it is•
no longer live.
Switch off the machine before carrying out any•
maintenance or repair operations or while it is not
in use.
Wear safety gloves, clothing, aprons and boots•
which are dry and free from holes.
Insulate the component and the earth by means•
of mats or other means of providing sufficient in-
sulation if the welder is required to work on metal
surfaces or structures.
This machine must be installed and earthed in ac-•
cordance with its User Manual and with national,
local and municipal codes of practice.
The return cable must be attached correctly (clean•
contact surface, cable securely fastened, as close
as possible to the area to be welded).
Do not use damaged, worn or bare (uninsulated)•
cables which are of insufficient size or not prop-
erly assembled. If this is the case, they must be
replaced immediately.
The welding station must be correctly earthed.•
If the component to be welded has to be earthed,•
use a separate cable.
Use the appropriate connectors.•
Note the no-load voltage, which is limited to 80 V
r.m.s. for alternating current or 113 V for direct
current (the voltage required to strike the arc). The
maximum value for plasma cutting power sources is:
500 V.
Risk of inhaling fumes or
gases.
Welding generates fumes and gases which are
hazardous to health. Do not inhale the fumes.
Origin of the fumes and gases: Base metal, filler
metal, coating (flux) with welding by coated electrode,
shielding gas, solvents and materials covering the
metal to be welded.
In order to prevent risks:
Use breathing apparatus, such as filtering masks,•
assisted-ventilation masks, inducted air masks
and disposable masks.
Avoid chlorinated solvents.•
Ensure that the components are completely dry•
before welding.
Do not work alone!•
Trap the fumes and gases at source.•
Remove paint, oil or any other surface coating.•
Risk of burns to the eyes or
the skin due to radiation.
Les rayonnements de l’arc de soudage sont susRadi-
ation from arc welding is liable to cause burns to the
eyes and the skin.
Identifying the risks: Exposure to the radiation
emitted by the arc, generating intense visible and
invisible rays (ultraviolet and infrared), reflection of
the rays while welding metals such as aluminium and
stainless steel, arc strike, sparks, pin-holes created
by the tip of a tungsten electrode.
In order to prevent risks:
Wear gloves or leather gauntlets to protect your•
hands and lower arms.
Wear an apron or gaiters to protect your legs,•
knees and forefoot.
Wear a mask (headband-type, hand-held or elec-•
tronic mask) or goggles fitted with a suitable fil-
ter.
Use safety shields to protect nearby workers.•
Tie a scarf around your neck and button the neck•
of the protective clothing.

THE ART OF WELDING
P6 HW
PN-0110008 Rev. 12 7-100
Warning: hot surfaces – Risk
of burns.
Do not touch welded or flame-cut components with
bare hands. If such components have to be handled,
use the appropriate tools and/or wear welders’
gloves, thick and insulated, to prevent any burns.
Allow the components to cool before handling them
or welding them.
Risk of burns to the eyes
or the skin due to flying
sparks.
Wear gloves or leather gauntlets to protect your•
hands and lower arms.
Wear an apron or gaiters to protect your legs,•
knees and forefoot.
Wear a mask (headband-type, hand-held or elec-•
tronic mask) or goggles fitted with a suitable fil-
ter.
Use safety shields to protect nearby workers.•
Wear garments with long cotton or woollen•
sleeves, preferably free from any traces of oil or
grease. Do not wear clothing made from synthetic
fabrics.
Tie a scarf around your neck and button the neck•
of the protective clothing.
Wear welders’ safety boots.•
Risk of excessive heat or fire.
Maintain the equipment at the electrical worksta-•
tion in good operating condition, particularly the
cables carrying the feed and return current.
Maintain a minimum distance of 6 metres be-•
tween the welding equipment and any greasy, in-
flammable or dust-laden materials.
Use safety shields to protect nearby workers.•
Risk of explosion.
These risks are associated with the use and handling
of gas cylinders and flying sparks.
Do not use damaged cylinders.•
Store the cylinders in a well-ventilated area and•
restrict access to anyone other than authorised
personnel.
Never exceed a temperature of 55 ºC while stor-•
ing or using the cylinders.
Clearly identify empty cylinders to distinguish•
them from full ones.
Protect the cylinders from extremes of tempera-•
ture (ice, sunlight, sparks, etc.).
Check the connectors and hoses at regular inter-•
vals.
Use protective shields.•
Risk of serious injury caused
by rotating parts.
Do not place your hands near fans or any moving•
parts.
Keep all safety shields closed or in the ‘safety’•
position.
Risk of exposure to magnetic
fields.
The distance between the welding circuit and the
brain is of fundamental importance.
Never coil the cables around your body and cer-•
tainly not around your shoulders.
Advise your immediate superior if you are wearing•
a heart pacemaker. The interference generated by
the circuit requires special protective measures,
which must be applied in consultation with the
company doctor.
The operator must ensure
that no-one is exposed to the
hazardous area.

Training of the operators1. 4. 1.
Behind the power source, close to the Power On
switch, this label states that it is advisable to read
the instruction manual.
An instruction manual is delivered to the client. A
copy (all rights reserved) of this manual MUST be
given to the user personnel: operators, setters,
servicing personnel, etc. They must have appropriate
qualification for the tasks they have to do, in accord-
ance with the rules for new employees governed by
the Labour Code.
Access for maintenance and1. 4. 2. adjustments
Access to the upper parts of the equipment for adjust-
ment or servicing of units which are out of reach
of the operator must be undertaken using a stable
method, such as a ladder or stepladder, in accord-
ance with current safety standards.
It is strictly forbidden to climb up the equipment by
supporting oneself on pipework, a desk, a console or
bracket for the cycle control buttons, etc.
Ergonomics1. 4. 3.
Signs
Elements used for the signalisation, especially safety-
relevant parts (e.g. colours of push-buttons and
indicator lights — refer to NF X 08 003, NF EN 60073,
NF EN 894-1, ISO 369)) must not be modified in any
circumstances (inversion of the colours). Indicator
lights or buttons with whose colours become indis-
cernible due to aging or wear MUST be replaced.
Adequate illumination of work areas
Generally, welding equipment does not require the
use of spot lights, but rather a medium surrounding
level of illumination. The user must take all necessary
measures to ensure that the workshop is equipped
with suitable lighting (avoiding shadow areas and
glare) so that the operators do not suffer from exces-
sive tiredness or inconvenience.
Protectionintheeventofbreakdownorfailure1. 4. 4. of the equipment
During operations other than welding, personnel
must protect themselves by operating the isolation
device appropriate for the operation they have to
perform.
Danger in using a power source1. 4.
Work or maintenance procedures described in this manual may be accompanied by dangers or risks. Such
procedures are indicated by the following pictograms.
Risk or situation with danger of serious injuries or even
death.
Operating procedures and settings for preventing damage to equipment and special instructions will be marked
by the heading Remark or Note.

THE ART OF WELDING
P6 HW
PN-0110008 Rev. 12 9-100
Devices for isolating energy sources1. 4. 5.
Provision of shut off devices
Isolation devices (electrical, hydraulic, pneumat-
ic, ...) are mandatory. If they do not form part of
the POLYSOUDE supply (as is the case with porta-
ble installations), they MUST be provided by the user
who must install them at his cost and responsibility.
Operation of shut off devices
In accordance with the stipulations in the manufac-
turer’s technical manual, before actioning shut-off
devices (isolation of equipment from its source of
power), personnel must make sure that neither they
not any third party is in danger.
Prevention of fire and explosion1. 4. 6.
Welding equipment must not be used on premises
where inflammable, volatile or explosive products
are present. In no circumstances is the P6 power
source to be used to thaw pipework.
Preventing release of gas and fumes1. 4. 7.
It is the user’s responsibility to assess:
Inconvenience or unhealthy conditions inside his•
workshop and to take the necessary measures to
apply this clause.
Protection against radiation from electric arcs•
Safety instructions and protective arrangements•
must conform to NF EN 166 and NF EN 169.
Faultfinding1. 4. 8.
Only a qualified electrician is authorised to inspect,
test, adjust or repair electric or electronic equip-
ment.
Before any maintenance work can be carried out
or an instrument is connected to a circuit, the the
mains supply must be disconnected and a waiting
period of 2 minutes must be elapsed. These instruc-
tions are specified on the label at the right side of
the power source.
Always check that no voltage
is present even if the instal-
lation has been disconnected
from the mains. A capacitor
can store its voltage for a
long time after it has been
disconnected from the power
supply.
Never shunt or remove the safety devices or inter-
locks installed to protect personnel.
Never stand on a wet or humid floor during inter-
vention on electric or electronic devices. It is essen-
tial to avoid any leakage of liquids inside electric or
electronic equipment.
Never use volatile solvents or flammable solvents
in the workshop. The electric arc could ignite the
vapours or flammable liquids.
During faultfinding and maintenance work on
electrical equipment, take off any jewellery (rings,
watches, bracelets, etc.). Insulating shoes must be
worn when the situation requires it.

Introduction3.
The P4-P6 series3. 1.
The P6 HW belongs to a new series of universal and functional power sources for orbital TIG welding. The
complete realisation of a weld is the result of applying a WP (Weld Procedure), containing one or more programs
when several passes are necessary, documentation for preserving information about the weld, such as prepa-
ration of the tubes, electrode diameter and grinding angle, workpiece/ electrode distance, wire diameter and
feeding angle etc.
The WP also assists the operator in selecting solutions for successful welding. The features of the P6 HW gener-
ator are as follows:
The welding sequences are completely programmable in the operator’s language.•
The handling is simple and easy to learn because of the intuitive programming concept.•
Built-in library of WPs for fast weld parameter search.•
A measurement data acquisition system.•
An integrated printer for archiving and documentation to ISO 9000.•
WPs can be stored on internal memory or on a USB key.•
Modern power sources using inverter-technology.•
Mechanised welding can be carried out with all the convenience of the P4-P6 series power sources.•
Features of the P4-P6 power sources:
DC or pulsed weld current can be supplied.•
Continuous or pulsed movement and continuous or pulsed wire feeding in synchronisation with the weld•
current.
