SAlways wear recommended personal safety equipment, such as safety glasses, flame--proof
clothing, safety gloves.
SDo not wear loose--fitting items, such as scarves, bracelets, rings, etc., which could become
trapped or cause burns.
5. General precautions
SMake sure the return cable is connected securely.
SWork on high voltage equipment may only be carried out by a qualified electrician.
SAppropriate fire extinquishing equipment must be clearly marked and close at hand.
SLubrication and maintenance must not be carried out on the equipment during operation.
3 INTRODUCTION
The PSFt315M / 315 R is an self--cooled welding gun. The welding gun is
developed for use in robot applications or mechanised welding.
A range of accessories including welding tips, swan necks and contact nozzles are
also available.
Details of ESAB’s welding torches accessories can be found on page 13.

5 CONSUMABLES
5.1 Changing wire liner, replacing electrode conductors
5.1.1 Install the correct nipple
ESAB Connection EURO Connection
Note! 2 nipples are supplied with each welding liner, 1 for an ESAB connection and 1 for a
EURO connection.
5.1.2 Remove the gas nozzle and tip adator.
5.1.3 Install the wire liner in the welding gun.

5.1.4 Cut the wire liner to the correct length.
When cutting, the welding gun should be extended with the wire liner fully inserted in
the rear connection.
Cut the wire liner so that it protrudes by “X” in accordance with the table below.

Sharp edges are not allowed on the inside of the wire liner guide after cutting.
5.1.5 Reinstall the tip adaptor and gas nozzle.
5.1.6 Install the welding gun on the machine.
a) Turn the connecting piece clockwise when you encounter resistance
b) The welding rod goes in
5.2 Interchangeable connectors
Connectors are manufactured with the same measurements between the mount and
the tip of the contact tip and are therefore directly interchangeable.
For dimensions and guaranteed tolerances, see diagram on page 9.
5.3 Compressed air cleaning
The connector has a connection and ducts for compressed air cleaning of the gas
nozzle.

5.4 Contact tip
Contact tips are selected according to electrode diameter, type of shielding gas and
rating of the welding current being used. See table on page 13.
The contact tips are initially selected with the guidance of the CO2table. If seizing
occurs in the event of high welding data with Argon or mixed gas, select on the basis
of the MIX, AR table.
For HELIX, the table applies regardless of shielding gas type. HELIX contact tips
must be combined with a special tip adaptor, see spare parts list. Note that the item
number for HELIX includes 2 contact tips + 1 locking nut for installation.
5.5 Wire liners
In order to achieve good welding rod feed, the wire liner should be selected in
accordance with the table on page 14. A PTFE--based wire liner produces less
friction and is kinder to the electrode, but normally has a shorter service life than a
steel spiral. It is suitable for all types of electrode, except for the majority of core wire
types thicker than 1.2 mm.
Steel spirals can be used for all except for stainless steel and aluminium electrodes.
For changing electrode guides – see the enclosed instructions.
Note! All welding guns are supplied with steel spirals for welding liner ∅1.0.
5.6 Gas nozzles
If you want a gas nozzle with a smaller opening diameter, this is available as an
accessory for each gun. See the spare parts list. Note that it is also possible to
exchange the connector type.
IMPORTANT! There is a spatter guard in the gas nozzle. This must be in place to
prevent welding spatter penetrating the connector.
For good function, the gas nozzle must always be screwed in as far as it will go.
5.7 Gas protection
Several factors combine to provide good gas protection. The most important of these
are:
1. Choice of shielding gas. -- Mixed gas and argon require a greater flow than
carbon dioxide
2. Set flow quantity. -- See technical data (should be measured at the gas nozzle).
3. Set welding current. -- High current requires a greater gas flow.
4. Position of the welding joint. -- A vertical position requires a greater gas flow.
5. Type of welding joint. -- An outer corner joint requires a greater gas flow than a
butt joint. A fillet weld joint requires a correspondingly smaller gas flow.
6. The angle of the welding gun against the workpiece -- below 45°entails a risk of
poor gas protection.

6 OPERATION
General safety regulations for the handling of the equipment can be found on
page 3. Read through before you start using the equipment!
The welding gun contains a lead for starting point searching. This is connected to the
ring--shaped adapter plug in the welding gun’s feeder end. The connection lead from
starting point searching (e.g. Smartac) is connected to the corresponding flat--pin
connection in the feeder’s terminal block.
7 MAINTENANCE
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
Regular servicing reduces unnecessary and expensive operational stoppages.
1. Welding spray in the gas nozzle impairs the gas protection and increases the risk
of flash--over.
--Clean regularly and use a moderate amount of welding paste or welding spray.
2. The spray guard in the gas nozzle should be replaced when its front end has
become thin.
3. Every time the electrode bobbin is replaced, the welding hose should be
disconnected from the feeder and blown clean with compressed air.
4. The end of the electrode may not have any sharp edges when it is inserted into
the welding rod guide. This is particularly important in the case of PTFE--based
welding rod guides.
8 SPARE PARTS AND ACCESSORIES
PSF 315 M / 315 R is designed and tested in accordance with the international and Eu-
ropean standards IEC/EN 60974--7 and EN 60974--7. It is the obligation of the service
unit which has carried out the service or repair work to make sure that the product still
conforms to the said standard.
Spare parts may be ordered through your nearest ESAB dealer, see the last page of
this publication. When ordering, please state product type, serial number, designa-
tion and spare part number in accordance with the spare parts list.
This facilitates shipment and ensures correct delivery.
