damages before every introduction.

6) Personal protective equipment in accordance with DIN EN 175, DIN EN 379 and

DIN EN 169.

The welder has to protect his complete body against radiation and burnings through protective

clothes and face protection during the work. In the process you have to wear gauntlets, aprons,

welding shield with protective filter (DIN EN 470-1 and BGR 189). You must not wear synthetic

clothes or sneakers instead you should wear high shoes and you have to wear a headgear if

necessary. The special equipment must be in accordance with the aforesaid and recognized

standards if you use that.

Safety instructions

As additional protection for the eyes against UV radiation, safety goggles with side

shields and corresponding face protection in accordance with BGR 192 and BGI 553

must be worn. Accident prevention regulation BGR 500 stipulates that it is the

responsibility of the employer to provide suitable personal protective equipment, while

§ 28 stipulates that it is the responsibility of the insured to wear suitable clothing.

7) Protection during welding with increased electrical hazard

Welding rectifier and welding power source have to be designed with „S“ after EN 60974-1

and BGI 534, if it appears direct current (DC) or alternating current (AC). Use insulating

materials against electrical contact as well as wet bottoms. You have to wear dry and

undamaged work clothes as well gauntlets and shoes with rubber sole. Vent the rooms,

install possible suctions and wear gas masks if it necessary (see detailed statement BGR 500

and BGI 533 section 5).

8) In order to prevent stray currents and the effects thereof (e.g. destruction of electrical

protective ground conductors), the welding return cable (workpiece cable) must be connected

directly to the workpiece to be welded or to the table (e.g. welding table, grid type welding

table, workbench, supporting the workpiece (see BGR 500). When installing the ground

connection, assure that there is a good electrical contact (remove rust, paint, etc.).

9) During the welding pauses, the welding torch is to be laid down on an insulated surface or

hang up in such a way that it is not in contact with the workpiece and is support connected

to the welding power source (see BGR 500). In the case of longer work pauses, the welding

unit must be switched off and the gas cylinder valve must be closed.

10) The shielding cylinder must always be protected against tumble down using a safety chain.

11) Under no circumstances the unit may be put into operation while it is opened. Apart from

safety regulations, sufficient cooling of the electrical components provided by the fan

hazards and protected against them. Safety partitions (“welding safety curtains”) must be

erected in accordance with DIN EN 1598.

13) No welding work may be carried out on containers in which gases, fuels mineral oils or

similar substances have been stored. (explosion hazard). See §31 UVV BGR 500ÖEven if

they have been empty for a long timeÕ See § 31 of accident prevention regulation BGR

500.

14) Welds which will be subjected to high loads and which need to meet specific safety

requirements may only be carried out by specially trained and qualified welders.

Safety instructions

15) Never bring the torch to your face. When the torch switch be unintentional put on is it

possible that you will be injured by the wire.

16) In areas at particularly high risk of fire, the welder must obtain a welding permit and have

this on his person throughout the duration of the welding work. On completion of welding, a

fireguard must be delegated to ensure fire protection.

17) Ventilation measures must be applied in accordance with BGI 553 section 9.

18) The hazard to eyesight must be indicated by means of a sign at the workplace „Caution! Do

not look into the arc!”

2.3

Duty cycle

The duty cycle measurings have been carried out in accordance with EN 60974-1 / VDE 0544

part 1 (10 min working period).

60% duty cycle means:

After 6 minutes welding period must be carried out a welding pause from 4 minutes.

The electrical components are thermally protected against overheating.

2.3.1

Filter attachment

The duty cycle from the unit will be reduced if you use filter attachment. Though is the air

permeability of the filter mats important. Entscheidend ist dabei die Luftdurchlässigkeit der

Filtermatten. The frequency of cleaning is dependent from the degree of utilisation and from the

workplace relationships. If you change the filter mats, you have to use only the original filter

mats with the article number 005.0.1048.

!!! If you ignore this statement, the warranty claim will be voided!!!

2.4

Instructions to avoid interference

The welding unit has been manufactured in accordance with the requirements of guideline EN

50199 regarding electromagnetic compatibility. It is nonetheless the responsibility of the user to

ensure that the welding equipment is installed and operated in accordance with the

manufacturer instructions. If electromagnetic interference is detected, it is the responsibility of

the users of the welding equipment to find a solution with the technical assistance of the

manufacturer´s. In some cases, it may be sufficient simply to ground the welding current circuit.

In other cases, it may be necessary to build a complete shield for the welding power source and

workpiece using the input filters. In all cases, electromagnetic interference must be reduced to

avoid any possible malfunctions.

Note: For safety reasons, the welding current circuit may or may not be grounded. No

modifications may be made to the grounding without the approval of an expert who is able to

determine whether the changes might increase the risk of accidents, e.g. by allowing parallel

welding current return paths which could destroy the ground conductors of other equipment.

Further instructions are contained in TEC 974-XX "Arc welding equipment – installation and

use".

Safety instructions

2.4.1

Evaluation of the installation site

Before installing the welding equipment, the user must evaluate potential electromagnetic

problems in the vicinity. The following must be considered:

¾ Other power cables, signal and telecommunication cables above, below and next to

the welding equipment.

¾ Radio and television transmitters and receivers.

¾ Computer and other control devices.

¾ The health of the peoples in vicinity, for example the use of pacemakers and hearing

aids.

¾ Calibration and measuring equipment

¾ Interference immunity of other devices in the vicinity. The user must ensure the

electromagnetic compatibility of other devices used in the vicinity. This may require

additional safety measures.

2.4.2

Procedures to reduce emitted interference

a) Mains supply

Welding equipment is to be connected to the mains in compliance with the

recommendations of the manufacturer. If interference occurs, it may be necessary to

take additional precautions, e.g. filters for the mains connection. Make sure that the

power cable of welding equipment is installed in a fixed position shielded by means of a

metal conduit or similar. The entire length of the shield must be electrically connected.

The shield must be connected to the welding power source in the way to obtain a good

electrical contact between the metal conduit and the housing of the welding unit.

b) Maintenance of the welding equipment

Welding equipment must be maintained regularly in accordance with the

recommendations of the manufacturer. All access and service doors and covers must be

closed and fastened securely when the welding equipment is in operation. No

modifications whatsoever may be made to welding equipment with the exception of

modifications and adjustments specified in the manufacturer´s operating instructions.

Safety instructions

c) Welding cables

Welding cables should be kept as short as possible and routed close together on or near

the floor.

b) Equipotential

It is available to interconnect all metallic parts in and next to the welding equipment.

Metallic parts connected to the workpiece can, however, increase the risk of the welder

receiving an electric shock by touching these metallic parts and the electrode

simultaneously. The welder must be electrically insulated against all these connected

metallic parts.

c) Grounding the workpiece

If the workpiece is not connected to the ground for electrical safety reasons, or due to

the size and position of the workpiece, e.g. steel structure or outer wall of a ship,

grounding the workpiece may in some cases, but not all, reduce emitted interference. It

must be ensured that grounding the workpiece will not increase the risk of accidents for

the user and cannot cause the destruction of other electrical equipment. If necessary,

the grounding of the workpiece must be carried out by means of a direct connection to

the workpiece. In countries where a direct connection is prohibited, the connection must

be made by means of suitable reactors, selected in accordance with national regulations.

d) Shielding

Selective shielding of other cables and devices in the vicinity can reduce interference

problems. For special applications, it may be worth considering shielding the entire

welding system.

Introduction

3. Introduction

The unit must be secured against unintentional fall down. The air intakes must be free otherwise

there is danger of overheating. Make sure that no metallic abrasive dusts can be absorbed with

the cooling air. Metallic abrasive dusts are electrically conductive and these can lead to internal

arcing. These internal arcing can damage the device.

Attention! If extension cable be used:

• Only use lines with a minimum diameter of 2.5 mm².

• Unroll the entire cable drum (hazard of overheating)

Attention! If it be put into operation with a power unit:

• The rated power output of the power unit must be at least 10%

greater than the maximal power input of the welding unit.

• Lock the bayonet lock. Fixate the pole terminal of the ground cable

at the workpiece. The contact point must be cleared of paintworks,

layers of fat and oxide layers.

• Switch on the unit.

After starting the unit starts the run up phase. These begin with a lamp test (all lamps on the

control panel light up simultaneously short). Up next on display the information of the

software, the plant system as well as the machine settings as short text message.

5.1

To perform the Basic settings

The welding unit have available special attuned characteristic lines for different electrode types

thereof results ideal arc behaviour. This has the advantage that many other important Settings

are omitted, because characteristic lines present functions as for instance the functions of

current readjustment with short arc. Therefore, the welder has to carry out only few basic

settings.

• Carry the step switch 1 in position and adjust the

function with the rotary knob. 4 The display presents the

following information.

„A“ Display shows the welding current

„V“ Display shows the welding voltage

„A-V“ Display works in duplex operation and it shows the

welding current and the welding voltage alternate.

5.2

Hotstart settings for the welding current and the parameter

At first the height of the needed welding current is based upon the used electrode diameter. In

addition the material thickness of the base material, the material and the welding position have

essential influence on the needed current so that only approximate reference values will be

furnished on this position.

The following worths are the benchmark:

Electrodes- Ø (mm) 2,0 2,5 3,25 4,0 5,0

Current (A) 40-80 60-100 90-150 140-180 170-230

So that you obtain a good fusion penetration in the area of the initial weld, you can use the

hotstart function. During the hot start time, the welding current will be increased by a defined

percentage value over the value of the welding current. The accelerated fusing will be enabled

during the start phase therefore. The current drops to the value of the appointed welding

current after the expiration of the hotstart time. The hotstart current and hotstart time can be

changed, so you can ideal adjust the requirement.
