 Arc welding creates sparks

and drops of melted metal.

The welded workpiece starts

to glow and remains hot for

a relatively long period.

Therefore, do not touch the

workpiece with bare hands.

 Arc welding can cause

vapours to be release that

may be hazardous to health.

Be careful not to inhale these

vapours.

 Protect yourself from the

harmful effects of the electric

arc and keep people that are

not involved in the work away

from the arc maintaining a

distance of at least 2 m.

ATTENTION!

 During the operation of

the welding device, other

consumers may experience

problems with the voltage

supply depending on the

nection point. In case of doubt,

please contact your energy

supply company.

 During the operation of the

welding device, other devices

may malfunction, e.g. hearing

aids, cardiac pacemakers, etc.

z Potential hazards during

electric arc welding

There are a series of potential

hazards that can occur during

electric arc welding. It is there-

fore particularly important for the

welder to observe the following

rules to avoid endangering him/

herself and others and to prevent

damage to people and the

device.

 Work on the voltage side,

e.g. on cables, plugs, sockets

etc., may only be carried out

by qualified electricians

according to national and

Safety instructions

11

GB

local regulations.

 In the event of accidents,

disconnect the welding

devoice from the mains

voltage immediately.

 If electrical contact voltages

occur, switch off the device

immediately and have it

checked by a qualified

electrician.

 Always ensure good electrical

contacts on the welding

current side.

 Always wear insulating gloves

on both hands during welding

work. These provide protection

from electrical shocks (no-load

voltage of the welding cur-

rent circuit), harmful radiations

(heat and UV radiation)

and incandescent metal and

splashes of slag.

 Wear sturdy, insulating shoes.

The shoes should also insulate

when exposed to moisture.

Loafers are not suitable as

falling incandescent metal

droplets can cause burns.

 Wear suitable protective

clothing, no synthetic garments.

 Do not look into the electric

arc without eye protection;

only use a welding mask with

the prescribed protective glass

as per EN. In addition to light

and heat radiation, which

can dazzle or cause burns,

the electric arc also emits UV

radiation. Without suitable

protection the invisible ultra-

violet radiation can cause very

painful conjunctivitis which

is not apparent until several

hours later.

Furthermore, UV radiation

can cause burns sunburn-like

effects on unprotected parts of

the body.

 Any persons in the vicinity

of the electric arc or helpers

must also be informed of the

dangers and be equipped

with the necessary protective

equipment. If necessary, set up

protective walls.

 Ensure an adequate supply

of fresh air whilst welding,

particularly in small spaces, as

it produces smoke and harmful

gases.

 No welding work may be car-

ried out on containers

that have been used for

storing gases, fuels, mineral

oils or similar – even if they

have been empty for a long

time – as possible residues

may present a risk of explosion.

 Special regulations apply in

rooms where there is a risk of

Safety instructions

12

GB

fire or explosion.

 Welded joints that are subject

to heavy stress loads and are

required to comply with

certain safety requirements

may only be carried out by

specially trained and certified

welders. Examples of this are

pressure vessels, running rails,

tow bars, etc.

ATTENTION! Always connect

the earth terminal as close as

possible to the point of weld to

provide the shortest possible

path for the welding current

from the electrode to the earth

terminal. Never connect the

earth terminal to the housing

of the welding device! Never

connect the earth terminal to

earthed parts far away from

the workpiece, e.g. a water

pipe in another corner of the

room. This could otherwise

damage the protective bond-

ing system of the room you

are welding.

 Do not use the welding device

in the rain.

 Do not use the welding device

in a moist environment.

 Only place the welding device

on a level surface.

 The output is rated at an ambi-

ent temperature of 20 °C. The

welding time may be reduced

in higher temperatures.

Danger of electric shock:

An electric shock from

a welding electrode can

be fatal. Do not weld in rain

or snow. Wear dry insulating

gloves. Do not touch the elec-

trode with bare hands. Do not

wear wet or damaged gloves.

Protect yourself from an electric

shock with insulation from the

workpiece. Do not open the

device housing.

Danger due to welding

smoke:

Inhaling welding smoke can harm

your health. Keep your head out

of the smoke. Use facilities in

open areas. Use ventilation to

remove smoke.

Danger due to welding

sparks:

Welding sparks can cause an

explosion or fire. Keep flammable

substances away from the

welding area. Do not weld

next to flammable substances.

Welding sparks can cause fires.

Keep a fire extinguisher nearby

and an observer ready to use it.

Do not weld on top of drums or

any closed containers.

Danger due to

electromagnetic fields:

Welding current produces

electromagnetic fields. Do not

use along with medical implants.

Never wrap the welding cables

around the body. Consolidate

welding cables.

z Safety information spe-

cific to the welding mask

 Using a bright light source

(e.g. lighter) always check

the welding mask is working

properly before starting to weld.

 Welding splashes can

damage the glass shield.

operation must not be higher

than 48 Volts (effective value).

Based on the output voltage

this welding device may be

used in these conditions.

z Protective clothing

 Whilst working, the welder

must protect all body parts

from radiation and against

burns by means of appropriate

clothing and face protection.

Remember the following steps:

– Put on protective clothing

before welding.

– Wear gloves.

– Open windows to ensure

air supply.

– Wear protective goggles.

 Wear gauntlet gloves made of

suitable material (leather) on

both hands. These must be in

good condition.

 Wear suitable aprons to

protect clothing from sparks

and burns. If work such as

overhead welding is required,

wear a protective suit and,

if necessary, a head guard.

z Protection against

radiation and burns

 Warn of the danger to the

eyes by hanging up a sign

saying “Caution! Do not look

into flames!“. If possible,

shield the work areas to

protect persons in the vicinity.

Keep unauthorised persons

away from the welding area.

 Walls in the direct vicinity

of fixed work areas should

be neither light coloured nor

glossy. Windows should be

blocked off to at least head

height to prevent the escape or

reflection of radiation, e.g. by

painting with a suitable paint.

prevent the risk of an electric shock, injury or

damage.

z Using the device

z Switching the device on

and off

 Switch the welding device on and off

on the main

5

switch. If you do not

intend to use the welding device for an

extended period, remove the plug from

the power socket. This is the only way to

completely de-energise the device

z Setting the welding current

The switches on the front of the welding de-

vice can be used to set the desired welding

currents.

The rotaryswitch for welding current setting

7

on the front of the welding machine can

be used to set the desired welding currents.

The corresponding settings can be found in

the following table.

Voltage (V) Wire feed

Welding

current

A 2 – 4 25 – 75

B 3 – 5 55 – 85

C 3 – 6 60 – 100

D 4 – 8 65 – 105

E 5 – 9 75 – 110

F 5 – 10 80 – 115

G 5 – 10 85 – 120

The necessary welding current depends on

the welding wire diameter used, the material

thickness and the desired penetration depth.

z Setting the wire feed

In order to generate a constant arc, the

setting wheel for the wire feed

8

can be

used to fine-tune the wire feed. You are

recommended to use a setting in the middle

range to start with, and then reduce or

increase the speed as required.

The necessary welding current depends on

the welding wire diameter used, the material

thickness and the desired penetration depth.

Similarly, the gaps to be bridged between

the workpieces to be welded must be ob-

served.

Overload protection

The welding device is protected against

overheating by means of an automatic

protection device (thermostat with automatic

restart). The protective device interrupts

the overload of the current circuit and the

 Allow the device to cool down (approx.

15 minutes) for the activation of the

protection device. As soon as the yellow

again.

Welding mask

HEALTH HAZARD!

If you do not use the welding mask, harmful

UV radiation and heat emitted by the electric

arc could damage your eyes.

Always use the welding mask for welding

work.

z Welding

RISK OF BURNS!

Welded workpieces are very hot and can

cause burns.

Always use pliers to move hot, welded

workpieces.

Please proceed as follows once

you have electrically connected the

welding device:

 Connect the earth cable to

4

the

workpiece that is to be welded using

the earth terminal. Please ensure good

electrical conductivity.

 The area to be welded on the workpiece

must be free of rust and paint.

 Choose the desired welding current and

wire feed depending on the welding

wire diameter, material thickness and

desired penetration depth.

 Switching the device on.

 Hold the welding mask

23

in front of

your face and guide the torch nozzle

9

to the position on the workpiece that is to

be welded.

 Press the torch button

11

, in order to

generate an arc. Once the electric arc is

burning, the device feeds wire into the

weld pool.

 If the welding lens is big enough, the

torch

10

is slowly guided along the

desired edge. The distance between the

torch nozzle and workpiece should be as

small as possible (it must not be greater

than 10 mm).

 If necessary, oscillate a little to increase

the size of the weld pool. For inexperi-

enced welders, it is often difficult initially

to create a decent electric arc. To do so,

the welding current and wire feed rate

must be set correctly.

 You can work out the ideal settings for

the welding current and the wire feed

rate by carrying out trial welds on a test

piece. A properly set electric arc has a

mild, uniform buzzing sound.

 The penetration depth (corresponds to

the depth of the welding seam in the

material) should be as deep as possible

without allowing the welding pool to fall

through the workpiece.

 Reduce the wire feed rate in case of a

rough or hard rattle or switch to a higher

power level (increase welding current).

 If the wire feed rate is too high and/or

the welding current too low, the welding

wire will not melt properly. Consequently,

the welding wire repeatedly dips in the

welding pool as far as the workpiece.

 A quiet, muffled sound with a flickering

electric arc indicates the wire feed is

too low.

 Increase the wire feed rate or switch to

a lower welding current. If the welding

current is too high, the wire will melt

before it even reaches the weld bed.

This results in droplet formation on the

welding wire as well as splash and an

irregular electric arc.

 The slag can only be removed from

the seam once it has cooled down.

To continue welding an an interrupted

seam:

 First remove the slag at the starting point.

Using the device

19

GB

 The electric arc is ignited in the weld

groove, guided to the continuation point,

melted properly and finally the weld

seam is continued.

CAUTION: Please note that the torch

must always has to be placed on down

an insulated surface after welding.

 Always switch off the welding device

after completing welding work and

during breaks and pull the plug from

the mains socket.

z Create a weld seam

Forehand welding

Push the torch forwards.

Result: The penetration depth is lower,

broader weld width, flatter weld bead

(visible surface of the seam) and greater

fusion error tolerance.

Backhand welding

The torch is dragged from the weld seam.

Result: Greater penetration depth, narrower

weld width, higher weld bead and lower

fusion error tolerance.

Welded joints

There are two-basic types of joints in

welding: Butt welds and angle welding

(outer edge, inner edge and overlapping).

Butt welds

With butt welds of up to 2 mm, the weld

edges are completely brought together.

For greater thicknesses, please proceed

as per the following table:

S

S = 1-3 mm 3-4 mm 4-6 mm

d = surface 0.5-1.5- mm 1.5-2.5 mm 2-3 mm

d = vertical 1-1.5- mm 1.5-2.5 mm 2-3 mm

d = front

surface

1-2 mm 2-3 mm 3-4 mm

Flat butt welds

Welds should be made without interruption

and with a sufficient penetration depth.

Therefore, it is extremely important to be

well prepared. The factors that influence the

quality of the weld result are: the amperage,

the distance between weld edges, the

inclination of the torch and the correspond-

ing diameter of the welding wire.

The steeper you hold the torch against the

workpiece, the higher the penetration depth

and vice versa.

T

To forestall or reduce deformations that can

happen during the material hardening pro-

cess, it is good to fix the workpiece with a

device. Avoid stiffening the welded structure

to prevent cracks in the weld.

These problems can be avoided if there is a

possibility of turning the workpiece so that

the weld can be carried out in two passes

running in opposite directions.

U

Welds on the outer edge

The preparation for this is very simple.

V

However, it is no longer expedient for thicker

materials. In this case, it is better to prepare

a joint as shown below, in which the edge of

the plate is angled.

W

Fillet weld connections

A fillet weld is created if the workpieces are

perpendicular to each other. The weld should be

shaped like a triangle with sides of equal length

and a slight fillet.

Welds on an inner edge

The preparation for this weld joint is very

simply and is carried out for thicknesses of

5 mm. The dimension “d” needs to be re-

duced to a minimum and should always be

less than 2 mm.

X

However, it is no longer expedient for thicker

materials. In this case, it is better to prepare

a joint as shown in Figure W, in which the

edge of the plate is angled.

Y

Overlap welds

The most common preparation is that with

the straight weld edges. The weld can be

released using a standard angle weld seam.

Both workpieces must be brought as close to

each other as possible.
