The following accident prevention regulation is applied for welding with MIG/MAG welding

unit, type M 301, M 351, M451, M551:

BGV D1 (earlier VBG 15) * Welding, cutting and allied processes.

A copy of this regulation should be readily accessible in every welding shop. The stipulations

of this regulation are to be observed in the interests of safe and correct welding operation.

* Available from the trade association responsible or

Carl Heymanns-Verlag, Luxemburger Strasse 449, 50939 Cologne.

2nd1 Safety instructions

This unit is manufactured according to the requirements and stipulations of EN 60974.1 /

VDE 0544 part 1. BGV D1 (earlier VBG 15) of the trade association for precision

engineering and electrical engineering are as well valid.

1) In case of an accident, the cutting unit must be disconnected from the mains

immediately.

2) If electrical contact voltages arise, switch off the unit immediately, disconnect it from

the mains and proceed to inspection by a qualified electrician or by our Service

Department.

3) Before opening the unit, disconnect it from the mains supply.

4) Repair work may only be carried out by a skilled electrician or by our Service

Department.

5) Before the unit is put to operation, check it visually, as well as the torch and all cables

DIN EN 169.

During the work, the welder’s body must be completely protected against radiation

and burns by means of protective clothing and face protection. Long gloves, aprons

and welding shields with welding filters conforming to DIN EN 470-1 and BGR 189

must be worn.

Synthetic clothing are excluded. Shoes must be closed, not opened (due to spatters). If

necessary, protective headwear must be worn (e.g. for overhead welding). If cover

glasses are used, these must be in accordance with the norms specified above.

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 BGV D1 § 27 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.

3

7) Protection when welding under increased electrical risks

Welding rectifiers and welding power sources which can optionally be used for either

direct or alternating current must be marked "S" in accordance with EN 60974-1 and

BGI 534.

Use insulating materials to protect you against contact with electrically conductive

parts and damp floors. Wear dry, undamaged work clothing, long gloves and footwear

with rubber soles. Ventilate rooms, install extraction systems if required, and wear

respiratory protective equipment if necessary (see Procedural instructions BGV D1

§ 27 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 BGV D1 § 20).

When installing the ground connection, assure that there is a good electrical contact

(remove rust, paint, etc.).

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

hung up in such a way that it is not in contact with the workpiece and its support

connected to the welding power source (see § 20 BGV D1).

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 gas cylinder must always be protected against tumbling downing using a

safety chain.

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

(e.g. for repair work). Apart from the safety regulations, sufficient cooling of the

electrical components provided by the fan cannot be guaranteed.

12) In accordance with BGV D1 § 5, people in the vicinity of the arc must also be

informed of the hazards and protected against them. Safety partitions (“welding safety

curtains”) must be erected in accordance with DIN EN 1598.

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

or similar substances have been stored Öeven if they have been empty for a long

timeÕ (risk of explosion). See § 31 of accident prevention regulation BGV D1.

15) 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.

15) Never bring the torch close to your face.

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 fire-guard 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 work site

"CAUTION! Do not look into the arc!".

3rd Duty cycle

The duty cylce measurings have been carried out in accordance with

EN 60974-1 / VDE 0544 part 1 (10 min working period).

60% duty cycle means:

After a 6 min. welding period a 4 min welding pause must be respected. The electrical

components are thermally protected against overheating.

4th Instructions to avoid interferences due to electromagnetic influences

EMC

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’s instructions. If electromagnetic interference is detected, it is the responsibility

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

manufacturer. 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".

a) Evaluation of the installation site

Before installing the welding equipment, the user must evaluate potential

electromagnetic problems in the vicinity. The following must be taken into

consideration:

a. Other power cables, control cables, signal and telecommunication cables above, below

and next to the welding equipment

¾ Radio and television transmitters and receivers

¾ Computers and other control devices

¾ The health of people in the vicinity, e.g. use of heart pacemaker 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.

b) Procedures to reduce emitted interference

1) 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.

5

2) 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.

3) Welding cables

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

near the floor.

4) Equipotential bonding

It is advisable 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.

5) 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.

6) 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.

6th General Information MIG/MAG Welding Units

MIG/MAG welding is a system where the welding wire is the carrier of the electric arc.

Surrounding the contact tip (wire feed nozzle) is the gas nozzle, that emits the protective gas.

The welding bead is protected in this way from oxygen contamination.

6th1 Metal Inert Gas Welding (MIG)

In this technology inert gases are used. Mostly used are argon, helium, and mixtures of these

components. These gases do not react with other materials, they are inert. They are manly

used for welding aluminium, copper, titanium or other non ferrum metals.

6th2 Metal Active Gas Welding (MAG)

For MAG welding gases like CO2, argon, and mixtures of these components are

used. For special purposes also mixtures of C02, argon and oxygen can be used. Mild steel

and stainless steel is welded with theses gases.

6th3 Protective Gases

The gas flow is depended on several parameters:

- gas density

- material of work piece

- distance gas nozzle to work piece

- diameter of gas nozzle

- geometry of weld

For welding steel and stainless steel the gas flow is in the range of about 8 to 16 I at welding

currents of 40 -400 A. For welding aluminium the gas flow is about 30 % more.

6th4 Welding Wires

Different diameters of welding wires are available:

0.6 / 0.8 / 0.9 / 1.0 / 1.2 / 1.6 / 2.4 mm.

6th5 Duty cycle

The duty cycle is measured at temperature of 40°C and a 10 minutes period. At lower

temperatures the duty cycle is higher.

7th Installation

7th1 Main Supply

The main supply must be connected by a trained person. The main supply voltage is displayed

on the front or rear panel of the machine. A connection to protection earth must be done.

7th2 Earth Lead (Work Cable)

The earth lead must have an excellent ground. The clamp should be attached to a clean, paint

and rust free area on the work piece or on the welding table.

9

7th3 Welding Torch

Attach the hose assembly to the Euro-connector with the flange nut.

7th4 Gas Connection

Place the gas bottle on the gas bottle holder and secure it with the safety chain. Remove the

cap and open the bottle momentarily to purge the valve. Install the regulator on the bottle

valve. Connect the gas hose from the machine to the pressure reducer. Slowly open gas valve

and set the gas flow.

7th5 Wire Installation

Place the wire spool over the wire drive. Loosen the end and cut off the bent end

section. Hold the wire to prevent unwinding of the spool. Open the tightening lever and lift

the pressure finger. Feed the wire into the wire feed guide. Push the wire forward onto the

wire drive roller grooves. Close the tightening lever and switch on the machine.

Check the wire feeding: Place your hand 10 cm in front of the contact tip. Let the wire run

into your hand. If the wire is running, the pressure of the drive rollers is ok.

8th Installation of the Machine

Place the machine at least 0.80 m from a wall etc. to guarantee the cooling air can go through

the unit. The room temperature should not exceed 40°C.

9th Options

9th1 Welding Stainless Steel

Exchange the parts according to the table listed in section “wire feeder” A Teflon liner

in the torch hose must be used. As gases we recommend mixtures of argon and 2.5

%CO2.

9th2 Welding Aluminium

Do not use wire diameters less than 1.0 mm. Max. length of the torch should not exceed 3 m.

Use Teflon liner in the torch hose. See section 'wire feeder' for exchange of parts for welding

of aluminium.

10th Maintenance

The machine should be cleaned in regular intervals to guarantee a proper operation. The

length of the cleaning interval depends on the operation time, surrounding atmosphere etc.

IMPORTANT: Before opening the machine disconnect the main supply!

11th Cleaning

Welding unit: Open the side covers. Remove dust from all parts of the

machine.

10

Welding torch: Control the welding torch after welding of 50 kg wire.

Remove, clean and replace the wire core. Clean with a cleaning

solvent. Blow dry with compressed air. When replacing the

wire core, insure that there are no kinks. The gas nozzle must be

sprayed with a silicon-free spray to prevent the weld spatters

from sticking to the nozzle. The contact tip is a consumable

item and must be replaced as required.

Attention: Do put oil to the wire core or the drive roller on the

wire feed unit.
