1 SAFETY

Users of ESAB equipment have the ultimate responsibility for ensuring that anyone who

works on or near the equipment observes all the relevant safety precautions. Safety

precautions must meet the requirements that apply to this type of equipment. The following

recommendations should be observed in addition to the standard regulations that apply to

the workplace.

All work must be carried out by trained personnel well-acquainted with the operation of the

equipment. Incorrect operation of the equipment may lead to hazardous situations which can

result in injury to the operator and damage to the equipment.

1. Anyone who uses the equipment must be familiar with:

○ its operation

○ location of emergency stops

○ its function

○ relevant safety precautions

○ welding and cutting or other applicable operation of the equipment

2. The operator must ensure that:

○ no unauthorised person is stationed within the working area of the equipment when it

is started up

○ no-one is unprotected when the arc is struck or work is started with the equipment

3. The workplace must:

○ be suitable for the purpose

○ be free from drafts

4. Personal safety equipment:

○ Always wear recommended personal safety equipment, such as safety glasses,

flame-proof clothing, safety gloves

○ Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could

become trapped or cause burns

5. General precautions:

○ Make sure the return cable is connected securely

○ Work on high voltage equipment may only be carried out by a qualified electrician

○ Appropriate fire extinquishing equipment must be clearly marked and close at hand

○ Lubrication and maintenance must not be carried out on the equipment during

operation

CAUTION!

Read and understand the instruction manual before

installing or operating.

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.

4 OPERATION

4.1 General

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!

Read the operating instructions for the welding components, e.g. power source and connect

accordingly.

4.2 Connections

Tighten the connections for the torch carefully to avoid overheating the connection,

connection interference, mechanical damage or leakage of liquid or gas.

Connect water connections to the torch so that the red terminal is always connected to the

corresponding red terminal and the blue terminals are always connected to the

corresponding blue terminals.

4.3 Choice of electrode

By alloying the tungsten electrode with 1% to 2% lantha or cerium the electron discharge is

increased, which gives better striking and restriking and therefore increased arc stability.

Alloyed tungsten electrodes have a longer service life, tolerate higher currents and are less

likely to leave tungsten residue in the weld.

4.4 Grinding

Grind tungsten electrodes according to the following table:

NOTE!

Tungsten electrodes must be ground lengthways. If they are ground incorrectly

the arc may be unstable. When the welding current is increased the angle must

also be increased.

When welding with alternating current (AC) the electrode end must be gently rounded.

Grinding the electrode is then unnecessary. Light grading of the edge is sufficient. The

electrode forms itself if it is carefully overloaded. If the tip becomes ball shaped while welding

using alternating current, this is a sign that the current is too high for the diameter of

electrode being used.

4.5 Bending of the flexible torch

The life of the flexible torch is limited, the

maximum bending angle should be 45

degrees.

The life of the torch head can be prolonged by

proper technique.

Always make sure that the torch head is

supported by the thumb when you bend. This

prevents damages at sharp bendings.

5 MAINTENANCE

NOTE!

Regular maintenance is important for safe, reliable operation.

WARNING!

The mains supply must be disconnected before cleaning.

CAUTION!

All warranty undertakings from the supplier cease to apply if the customer

attempts any work to rectify any faults in the product during the warranty period.

5.1 Daily

• Check that all cables and hoses are undamaged and that there are no kinks in them.

• Check that the gas nozzle is free from defects and suitable for the work in question.

• Check that the shielding gas flows evenly and without restriction.

• Check that the electrode is undamaged and that the electrode has been ground to the

correct angle.

• Check the water flow at the unit's return line.

6 FAULT-TRACING

6 FAULT-TRACING

Read the operating instructions for the welding components, e.g. power source.

If the measures described below are not successful, please consult your dealer or the

manufacturer.

Problem Cause Solution
