Safety instructions

For Your Safety:

Ignoring the following safety precautions can be fatal.

Observe accident prevention regulations.

These operating instructions are valid only in conjunction with the relevant safety regulations, especially with accident prevention regulations VBG 9 and operating instructions of one of the welding machines from our product range!

Proper usage

This machine has been manufactured according to the latest developments in technology and current regulations and standards. It is to be operated only for the use for which it was designed

(see chapter Commissioning/Area of application).

Improper usage

This machine may be a hazard to persons, animals and property, however, if it is

•

not used as designed

•

used by unskilled persons who have not been trained,

•

modified or converted improperly

Our operating instructions will provide you with an introduction into the safe use of the machine.

Therefore please read them carefully and only start work when you are familiar with them.

Any person involved in operation, maintenance and repair of this machine must read and follow these operating instructions, especially the safety precautions. Where appropriate, this must be confirmed by signature.

Furthermore, the

•

relevant accident prevention regulations,

•

generally recognised safety regulations,

•

local regulations, etc. must be observed.

Secure gas cylinder

•

Place shielding gas cylinders in the holders provided for them and secure with safety chains or belts.

•

Take care when handling cylinders; do not throw or heat, guard against them toppling over.

•

For transport vehicles which can be moved by crane, the gas bottle must be removed before crane transport.

When moving and setting up the transport vehicle, it is only secure against falling to an angle of 10

°°°°

. Special attention should be paid to the fact that, when the machine is moved, additional danger results from obstacles on the floor as these can cause additional tilting moments.

Comprehensive and additional welding safety precautions can be found in the operating instructions for our welding machines. A list of the standards and specifications currently in force can also be found in these instructions.

Repair and modifications may only carried out by authorised, trained, specialist staff.

The warranty becomes null and void in the event of unauthorised interference.

Safety instructions

Notes on the use of these operating instructions

Our operating instructions will provide you with an introduction into the safe use of the machine.

Therefore please read them carefully and only start work when you are familiar with them.

These operating instructions are arranged into chapters.

To help you find your way around more quickly, in the margins you will occasionally see symbols along with the sub-headings. These symbols refer to particularly important passages of text which are graded as follows depending on their importance:

(Note): Applies to technical peculiarities which must be observed by the user.

(Warning): Applies to working and operating procedures which must be carefully followed to avoid damaging or destroying the machine.

(Caution): Applies to working and operating procedures which must be carefully followed to avoid endangering people and includes the "Warning" symbol.

Instructions and lists detailing step-by-step actions in given situations can be recognised by bullet points, e.g.:

•

Insert plug of welding current lead into socket

(chap. 5, G2)

and lock.

4.2

Transport/set-up

The points listed in chapters 4.2.1, 4.2.2, 4.2.3 und 4.2.4 are examples only.

More detailed information can be found in the general and specific safety and accident prevention regulations.

4.2.1

Crane transport

•

The transport vehicles can be transported by crane by attaching the lifting lugs to the fixing points (fig. 4/1).

Use only these fixing points for lifting by crane.

•

Before crane transport remove the gas cylinder from the transport vehicle.

•

Before crane transport, remove wire feed unit from transport vehicle.

•

If the transport vehicle has to be moved with the wire feed unit, ensure that the unit is sufficiently well attached and secured.

•

The wire coil must always be removed when moving the machine with a crane, with the wire feed unit attached.

•

When moving the machine with a crane with the wire feed units WELDON DRIVE 4L or

PHOENIX DRIVE 4L attached, ensure that the press arbor (chap.2, N1) is removed from the bracket (chap.2, M1) before attaching and securing the unit.

Fig. 4/1

•

During crane transport no-one should be standing under the suspended load.

•

Before lifting it must be ensured that all the fixing points are securely assembled.

•

Before and after lifting, check that the snap closures between the cooling unit and welding machine are sitting properly.

•

Before and after lifting, check that the holding plates for fixing the units to the transport vehicle are correctly positioned.

•

The clamping plates for housing the welding machine handle must be securely attached.

•

All loose parts such as accessories and welding torches are to be removed from the transport vehicle before lifting.

•

Only use undamaged cables for lifting.

•

Do not raise or lower the load suddenly.

4.2.2

Assembly

Risk of injury when assembling the machines on the transport vehicles.

•

Avoid the risk of injury by careful, prudent and foresighted actions during assembly onto the transport vehicle.

•

First fit the cooling module, then the welding machine and lastly the wire feed case.

•

For WELDON and PHOENIX DRIVE 4L wire feed units, the angle section of the A2 rail should be fitted so that it points downwards (fig. 4/7). Otherwise there is a risk of injuries from crushing when the wire feed units are rotating.

•

For housing WELDON and PHOENIX DRIVE 4 wire feed units, the angle section of the

A2 rail should be fitted so that it points upwards (fig. 4/9).

•

Always use original accessories and spare parts.

4/2

4 Commissioning

4.2.3

Installation

The transport vehicle must be installed on a firm base.

•

Do not position on uneven surfaces.

•

The floor must not be at an angle and must be level.

•

When moving and setting up the transport vehicle, it is only secure against falling to an angle of 10

°°°°

.

•

Caution is required on a sandy, loamy, soft, wet or slippery base.

•

Avoid projecting parts such as accessories and torches. There is the risk of becoming caught on the machine, e.g. people passing by.

•

Do not place on glowing slag or caustic liquids, or the wheels could be damaged.

4.2.4

Procedure

The following points must be noted when using the transport vehicle:

•

When moving and setting up the transport vehicle, it is only secure against falling to an angle of 10

°°°°

.

•

Prudent behavior is a necessity when using the transport vehicle.

•

Before using the transport vehicle, ensure that all fixing points are securely attached.

•

Before and after lifting, check that the snap closures between the cooling unit and welding machine, and the holding plates for fixing the units to the transport vehicle, are correctly positioned.

•

The clamping plates for housing the welding machine handle must be securely attached.

•

Caution: The centre of gravity of the loaded transport vehicle changes according to the load, e.g. with different sizes of gas cylinders.

•

Do not use sloping routes when pushing the transport vehicle.

•

The base on which the transport vehicle is moved must be level, firm and dry. If the base is uneven (e.g. ground beams) an additional securing device specific to the wire feed unit must be fitted.

Caution is required on a sandy, loamy, soft, wet or slippery base.

•

The route to be travelled by the transport vehicle should be checked for obstacles beforehand. Sufficient space must be ensured, particularly in narrow passages, such as doors. When using the transport vehicle there is a risk from objects on the ground, because additional tilting moments may arise.

•

Ensure that projecting parts such as accessories or welding torches do not become caught when pushing past obstacles.

•

If large gas cylinders in particular are assembled on the transport vehicle, the forces to be applied when using should be estimated correctly.

•

When pushing the transport vehicle keep both hands on the handles.

•

Do not move over glowing slag or caustic liquids, or the wheels could be damaged.

•

The chains for fixing the gas cylinders must always be hung correctly on the hooks provided for them and must by lying firmly against the gas cylinders.
