1 SAFETY

WARNING!

Arc welding and cutting can be injurious to yourself and others. Take precautions

when welding and cutting. Ask for your employer's safety practices which should

be based on manufacturers' hazard data.

ELECTRIC SHOCK - Can kill

• Install and earth the unit in accordance with applicable standards

• Do not touch live electrical parts or electrodes with bare skin, wet gloves or

wet clothing

• Insulate yourself from earth and the workpiece

• Ensure your working stance is safe

FUMES AND GASES - Can be dangerous to health

• Keep your head out of the fumes

• Use ventilation, extraction at the arc, or both, to take fumes and gases away

from your breathing zone and the general area

ARC RAYS - Can injure eyes and burn skin

• Protect your eyes and body. Use the correct welding screen and filter lens

and wear protective clothing

• Protect bystanders with suitable screens or curtains

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure therefore that there are no

inflammable materials nearby

NOISE - Excessive noise can damage hearing

• Protect your ears. Use earmuffs or other hearing protection.

• Warn bystanders of the risk

MALFUNCTION - Call for expert assistance in the event of malfunction.

Read and understand the instruction manual before installing or operating.

PROTECT YOURSELF AND OTHERS!

ESAB can provide you with all necessary welding protection and accessories.

CAUTION!

Read and understand the instruction manual before

installing or operating.

2 INTRODUCTION

PSF 250, 305, 405 and 505 form a series of self-cooling swan neck welding torches.

PSF wform a series of water-cooled swan neck welding torches.

PSF RS3 welding torches are equipped with program selectors for switching between preset

programs. Programs are preset at the welding power source.

PSF Cform a series of welding torches with smoke exhausters. The welding torches are

available with either self-cooling or water cooling systems and are of a swan-neck design.

PSF LD is a smaller welding torch. This welding torch is available in a variety of types; for

more information see the ordering number in the "Ordering numbers" chapter.

5 OPERATION

0458 870 201 -9- © ESAB AB 2014

5 OPERATION

General safety regulations for handling the equipment can be found in the "SAFETY"

chapter of this manual. Read it through before you start using the equipment!

5.1 Contact tip

The hole size of the contact tip is determined by the diameter of the wire, the type of inert

gas and the level of current used. See the "Wear parts" chapter.

5.2 Wire liner

The spiral steel wire liner that comes as standard with the welding torch can be used for all

types of wire of the intended size with exception of aluminium.

PTFE-wire liners are suitable for welding with all types of wires (Al, Ss, and Fe).

However, it is recommended that PTFE-wire liners are not used when welding using Fe and

CW wires that are thicker than 1.2 mm due to the increased instance of wear.

PTFE-wire liners have a considerably shorter life than the standard steel spiral.

In order to ensure that you enjoy a satisfactory level of wire feed, select a wire liner in the

table in the "Wear parts" chapter.

5.3 Replacing the wire liner

1. Fit the correct nipple.

NOTE!

Each wire guide is supplied with 2 nipples, 1 for ESAB connection and 1 for

EURO connection.

a) ESAB connection

b) EURO connection

2. Remove the gas nozzle and the tip adaptor.

3. Fit the wire liner in the hose package.

4. Cut the wire guide to the correct length using a projectile "X" as shown in the figure

below.

While cutting, the welding torch must be extended with the wire guide fully inserted into

the rear connector.

5. Remove sharp edges inside the liner after cutting.

5 OPERATION

0458 870 201 - 10 - © ESAB AB 2014

6. Fit the tip adaptor and the gas nozzle.

7. Fit the welding torch on the power source.

a) Turn the connecting section counterclockwise until it resistance is met.

b) The wire guide should go in.

5.4 Gas nozzle

There is a spatter protector fitted inside the gas nozzle. This must be in position during

welding in order to prevent the welding spatter jamming and thereby causing a short circuit in

the swan neck.

Gas nozzles with larger and smaller openings are available as accessories for each type of

welding torch. See the "Wear parts" chapter.

5.5 Gas protection

Several factors are important for good gas protection. The most important are:

1. Selection of shielding gas. Mixed gas and Argon require a greater flow

than carbon dioxide.

2. Set flow quantity. See Technical data (to be measured at the

gas nozzle.)

3. Set welding current. High welding currents requires greater gas

flow.

4. Position of welding joint. A vertical position requires greater gas flow.

5. Type of welding joint. External corner joints require a greater gas

flow than butt joints. Conversely, fillet joints

require a lower gas flow.

6. Smoke evacuation on the welding torch. Using smoke evacuation increases the need

for inert gas by 10-12%.

7. Angle of welding torch to the job. Anling the welding torch at less than 45° may

result in poor gas protection.

5.6 Gas flow meter

A gas flow meter to measure gas flow through the welding torch is available as an accessory

see the "Accessories" chapter .

5.7 Centrovac

Integrated smoke evacuation

You can tailor the level of suction by opening the damper on the topside of the handle.

PSF 250C/PSF 315C LD

When welding in narrow positions it may be necessary to reduce the suction. This can be

achieved by opening the slots as shown below.
