2.5 General safety instructions
Please note the following:
- Welding Welding machines may only be operated by
persons who have been instructed in the use of welding
equipment and are familiar with safety regulations.
- When welding, always wear protective clothing and
take care that other persons are not endangered by the
UV radiation of the arc.
- Avoid direct contact with the welding circuit; the open
circuit voltage provided by the welder is dangerous un-
der certain circumstances.
- The welding cables, tests and repairs may only be
connected when the welding machine is switched off and
disconnected from the mains.
- Before replacing consumable parts of the torch, the
welder must be switched off and disconnected from the
mains.
- The electrical installation must be carried out in accor-
dance with the relevant regulations and accident pre-
vention regulations.
- The welding machine may only be connected to a po-
wer supply system with a grounded neutral conductor.
- Make sure that the power socket is correctly connected
to the protective earth.
- The welder must not be used in humid or wet conditions
or in rain.
- Do not use cables with worn insulation or loose connec-
tions.
- Clean the materials that contain solvents or other sub-
stances that may give rise to toxic gases.
- If a liquid cooling unit is available, it may only be filled
with the welding machine disconnected and dis-
connected from the mains.
- Do not weld on containers, vessels or piping containing
or containing flammable liquids or gases.
- Never weld to containers that are under pressure.
- Remove all flammable substances (eg wood, paper, fa-
bric etc.)
- Provide sufficient air exchange or suitable means to re-
move the fumes released when welding close to the
arc. It is necessary to systematically investigate which
limit values apply to the particular composition, concen-
tration and duration of action of the welding waste ga-
ses.
- The gas cylinder must be protected from heat sources,
including sunlight.
- Provide functional electrical insulation of the electrode,
workpiece, and nearby (accessible) grounded metal
parts. Normally, it is sufficient to wear appropriate gloves,
footwear, headgear and clothing, and to use running
boards and insulating carpets.
- To protect against sparks, heat, visible and invisible ra-
diation, suitable eye protection must be worn (protec-
tive shield or protective cover with standardized radia-
tion glasses of steps 10 to 15 according to DIN 4647,
depending on the welding current).
- Do not wear contact lenses, the strong heat that the
bow gives off, they can merge with the cornea.
- Use functional fire retardant protective clothing and
avoid exposing the skin to UV and infrared radiation
from the arc; Shooters must also use umbrellas or non-
reflective curtains for third parties that are near the arc.
- Noise generation: If a daily level of 85 db (A) or higher
(LEPd) is applied to the person during particularly in-
tensive welding work, functional individual protective
equipment must be used.
- As the welding current transitions, electromagnetic
fields (EMF) are generated near the welding circuit.
The electromagnetic fields may affect medical aids (eg
pacemakers, respiratory aids or metal prostheses).
Appropriate protective measures must be taken for the
providers of such assistance, for example by denying
them access to the operating range of the welding
equipment.
- This welding machine meets the technical product stan-
dards for the exclusive use in the commercial sector
and for professional purposes. Compliance with the ba-
sic limit values that apply to the effects of electroma-
gnetic fields on people in the home environment is not
ensured.
The operator must take the following precautions to re-
duce the impact of electromechanical fields:
- The two welding cables are to be fixed as close to each
other as possible.
- The head and the hull should be kept as far away as
possible from the welding circuit.
- The welding cables must under no circumstances be
wrapped around the body.
- During welding, the body must not be in the middle of
the welding circuit. Hold both cables on the same side
of the body.
- Connect the power return cable to the workpiece as
close to the weld as possible.
- Never close close to the welding machine, sitting on the
welding machine or welding to the welding machine
(minimum distance: 50 cm).
- Do not leave any ferromagnetic objects near the wel-
ding circuit. - Minimum distance d = 25cm.
- Use the guards and secure them securely. Never work
without protections and get them working.
- Always keep the welder and your work environment
clean. Ensure adequate lighting.
- In principle, secure your workpiece when working with
suitable clamping devices. Make sure there is sufficient
contact surface.
- The welder must not be modified in design nor used for
purposes other than those foreseen by the manufactu-
rer.
- Never work under the influence of concentration-distur-
bing illnesses, fatigue, drugs, alcohol or medicines.
- Keep children and persons unfamiliar with the welder
away from their work environment.
- Do not pull on the mains lead to pull the plug out of the
socket. Protect the cable from heat, oil and sharp
edges.
- Protect the welding machine against moisture (danger
of short circuit)
- Before each use of the welding machine, make sure
that no parts are damaged. Damaged parts must be re-
placed immediately to avoid any danger.
- Do not overload the welding machine! You work better
and safer in the specified performance range.
- Only use original spare parts and accessories to avoid
possible dangers and accident risks.

Transport, Packaging, Storage
5 Transport, Packaging, Storage
5.1 Delivery and Transport
Check the welder for visible transport damage after deli-
very. If the welding machine is damaged, it must be re-
ported immediately to the transport company or the de-
aler.
5.2 Packaging
All packaging materials and packaging aids used by the
welding equipment are recyclable and must always be
recycled.
Packaging components made of cardboard are crushed
to give waste paper collection.
The foils are made of polyethylene (PE) and the uphol-
stery parts made of polystyrene (PS). These substances
must be handed over to a recycling center or to the re-
sponsible disposal company.
5.3 Storage
The welder must be set up in closed, dry and well-venti-
lated rooms with room temperatures between 15 and 35
degrees.It must not be exposed to moisture or intense
sunshine.
6 Principle of operation
The MIG / MAG welding system consists of a transfor-
mer with a downstream silicon rectifier, a welding choke
and a wire feed unit.
A step switch is used to set the required welding voltage.
Via a second switch, the desired wire feed speed of the
wire feed unit can be selected. By adjusting the wire feed
speed, the arc length and welding current can be adju-
sted to the welding position and task.
Fig. 2: Working principle of the welding machine
The device is used for welding various welding wires (for
example steel, stainless steel, aluminum) under a pro-
tective gas atmosphere (CO2, argon or Mixed gas).
The unit is cooled by a fan with air. When the permissible
temperature of the power components is exceeded, the
welding current is automatically switched off. This is indi-
cated by a warning light on the control panel.
The housing ensures the protection of the components
against external influences and against direct contact.
Depending on the application, there are different de-
grees of protection against penetration of solid bodies
and water. The degree of protection is indicated by the
letters IP, followed by two digits: the first digit indicates
the degree of protection against solid bodies and the se-
cond the degree of protection against water.
6.1 Principle of the metal inert gas welding
process
The principle of MIG / MAG welding is that a metal wire is
passed through the welding gun and melted in an arc.
The welding wire has to fulfill two tasks, on the one hand
it is the current-carrying electrode and on the other hand
at the same time the weld metal to be introduced. The
electric current is supplied via a welding current source
to the contact tube in the welding gun.
A protective gas flowing through the gas nozzle protects
the arc and the melt. The inert gas is either inert (MIG) or
active (MAG). Iinert gases do not react with the melt. Ex-
amples of gases of this category are argon and helium.
Active gases are involved in the processes between the
arc and the melt. Argon with a small amount of carbon
dioxide or oxygen is an ex-ample of an active gas. The
active component affects e.g. the penetration and / or
the sweat bath temperature.
Due to the high welding speed, the low distortion and the
minimal reworking, MIG / MAG welding is the most wi-
dely used welding process today. The high weld
strength, the outstanding thin sheet properties and the
simple, safe handling of steel, aluminum and stainless
steel make this welding process universal.

10 EASY-MAG-Series | Version 2.01
Principle of operation
The arc is formed between the workpiece to be welded
and the emerging metal wire. The metal wire serves as
both an electrode and as a deposition material; It is
wound on a spool and is constantly inserted into the bur-
ner by wire guide rollers. The welding current passes th-
rough the wire guide tip of the burner to the electrode.
The inert gas exiting through the nozzle protects the
electrode, the arc and the molten bath against the sur-
rounding air.
6.2 Functional principle of wire feeding
The wire conveyor unrolls the weldment wound on a bas-
ket or mandrel spool and conveys it through the hose
package to the torch. When using basket coils, a basket
coil adapter must be used. Mandrel coils can be used
without adapters. The wire feed roller is provided with a
groove for the wire guide and must be replaced accor-
dingly when using a thicker or thinner wire. The contact
pressure of the pressure roller is adjusted via the pres-
sure control and should be selected so that the wire
spool can still be stopped by hand while the drive is run-
ning. For aluminum, the pressure should be as low as
possible, but still allow a safe transport of the wire.

Principle of operation
6.4 Insert the welding wire roller
Open the flap of the welder and unscrew the nut from the
wire roll mandrel. Mandrel coils can be directly plugged
on, basket coils must be used when using basket coils.
Insert the roller so that the end of the wire is "left down"
(see Fig. 4). Fold the lever for the pressure adjustment to
the left to unlock the pressure roller, the pressure arm
folds up automatically. Insert the wire through the wire
entry into the wire inlet via the wire feed roller. Make sure
that the capillary tube 9 of the wire inlet nozzle is positio-
ned approx. 1 mm in front of the wire feed roller to en-
sure good wire guidance. Check the correct position of
the wire in the groove of the wire feed roller. Fold the
pressure arm down and lock it. Set the pressure correctly
with the print setup. (see Fig. 5)
6.5 Burner equipment
Current contact nozzle
The current nozzle transfers the electric current to the
wire electrode. Power nozzles are wearing parts and
must be replaced from time to time. Current nozzles are
available for various materials and wire diameters. For
aluminum special current nozzles are used.
Shield Cup
The protective gas nozzle has the task of directing the
protective gas emerging at the gas flow distributor to the
welding point. The protective gas nozzle must always be
kept clean and free of beads of sweat to guarantee pro-
tection of the welding bath from the ambient air. While
the conical gas nozzle concentrates the shielding gas on
the weld, the cylindrical gas nozzle covers a larger area.
Guide spiral
The wire guide spiral is pulled through the hose as-
sembly of the burner, in her the welding wire is passed to
the burner. The selection of the right wire guide spirals
depends on the material type and the wire diameter.
Souls are made of different materials and are available
for a variety of welding tasks. For aluminum, for ex-
ample, a special Teflon core must be used.
,
The accessories of the burner depend on the respective
welding task and must be adapted to it.
The standard delivery includes a SMB 15/3 m burner,
equipped with a flow nozzle (M 6 Ø 0.8 mm / 25mm).
CAUTION!
Before starting to feed the wire, make sure that the
welding machine is switched off and disconnected
from the mains.
NOTE!
The wire spool should still be able to be stopped by
hand while the drive is running. For aluminum, the
pressure should be as low as possible, but still allow
a safe transport of the wire.

The Easy - Mag 210 can either be operated with 230 V or
with 400 V. Depending on how the device is connected
to the mains, the selector switch must be brought into the
respective position for switching on.
The scope of delivery includes a coupling to operate the
device on a 230V socket.
7.5 Item function
A period between 0.1 and 4.5 seconds can be selected
via the point function switch. Pressing the torch button
starts the welding process. As soon as the set time has
elapsed, the power source is switched off automatically.
7.6 Display overload
When the maximum temperature of the power compo-
nents is exceeded, the welding current is switched off
(orange LED lights up). The overload shutdown may e.g.
after long welding with high current occur.
After cooling, the system automatically switches back to
the operating state.
7.7 Step switch
With the step switch (item 2) the required welding
voltage is set.
7.8 Wire feed control
About the stepless switch (Pos. 3) the wire feed motor is
given a certain wire feed speed. It should be noted that
the wire feed is adjusted to each switching stage at the
operating point setting.
Optimum wire feed speeds:
-EASY-MAG 171: Wire Fe – 0,8mm, Step 3
-EASY-MAG 193: Wire Fe – 0,8mm, Step 4
-EASY-MAG 213: Wire Fe – 0,8mm, Step 5
Automatic regulation of the wire feed speed (setting aid)
When selecting the wire feed speed level 5 is an auto-
matic control of the wire feed speed. The wire feed
speed is automatically set to an optimum value. The opti-
mum wire feed speed is automatically adjusted for any
given wire gauge and tension level for different materi-
als.
Thus, the welder can always work with an optimal wire
feed speed when using different voltage levels and ma-
terials, without having to adapt these in each case to the
different parameters.

ATTENTION MAGNETIC FIELD
Magnetic fields of power circuits can affect the func-
tion of pacemakers. Persons wearing vital electronic
devices of this type must consult with the physician
before traveling to areas where such welding equip-
ment is available.
Interference may occur in the following areas /
devices. For this, appropriate countermeasures must
be taken:
- Data transmission systems,
- Communication systems
- Control,
- Safety devices
- Calibration and measuring devices.
DANGER! ELECTRICAL VOLTAGE
Do not use the device outdoors in the rain!
ATTENTION!
The welder should be set up on a flat and sufficiently
stable surface to prevent it from slipping or tipping
over.
DANGER!
Danger of electrocution!
Contact with live components may cause mortal dan-
ger. Switched on electrical components can cause
uncontrolled movements and lead to serious injuries.
ATTENTIONG!
Work on the electrical installation and on the electri-
cal equipment may only be carried out by electrici-
ans!
Before starting any work on the installation and
connection to the power supply, the welding machine
must be switched off and disconnected from the
power supply.
CAUTION!
Before the following connections are made, make
sure that the welder is switched off and disconnected
from the power supply.
CAUTION!
When handling gas cylinders, the relevant safety
regulations must be observed. In particular, because
of the dangerously high internal pressure (up to 200
bar), gas bottles are to be protected against mechani-
cal damage, falling over and falling down, from war-
ming (max 50 ° C), from prolonged exposure to the
sun and from severe frost.
NOTE!
Interventions and repairs to pressure reducers are not
permitted due to the associated hazards. Defective
pressure reducers are to be sent to the service work-
shop.

EASY-MAG-Series | Version 2.01 17
Operation
- When selecting protective gas bottles, it should be
borne in mind that over-sized bottles can impair the fle-
xibility and stability of the welding system and cause it
to tip over. In order to avoid damage to the device or
the dangers arising from the gas cylinder, only appro-
priate bottle sizes should be used. We therefore re-
commend bottle sizes up to a maximum of 20 liters. At-
tach the bottle with straps.
- After removing the protective cap, briefly open the cylin-
der valve in a direction away from the body to remove
any impurities. Screw pressure reducer to the threaded
connection of the protective gas cylinder. Make a hose
connection between the pressure reducer and the gas
supply connection at the top left of the back of the unit.
Secure the gas hose to the unit using the union nut and
the hose clamp on the pressure reducer. Then check
the tightness of the connections.
- Screw the pressure reducer (*) to the valve of the gas
cylinder. If argon gas or a mixture of argon and CO2 is
used, insert a special reducer in between which is
available as an accessory.
- Connect the gas supply hose to the reducer and tigh-
ten the supplied hose clamp.
- Loosen the adjusting nut of the pressure reducer be-
fore opening the cylinder valve.
(*) The accessory must be purchased separately if it is not included with
the product.
9.4 Welding parameters
To obtain optimum welding results, the welding parame-
ters, such as the welding tension and wire feed speed,
must be adjusted according to the welding task, welding
position, material type and thickness. For every welding
wire diameter and every welding task optimal parame-
ters can be found. Among other things, they are recogni-
zable by the typical buzzing arc noise. If one deviates too
much from the optimal values, perfect welding is not pos-
sible.
Setting the welding parameters
After switching on the device, it is possible to start adju-
sting. First of all, the welding voltage is selected via the
STAGE SWITCH according to material thickness and
joint shape, then the wire feed speed is adjusted. For
coarse adjustment of the wire feed, the DRAHTVOR
PUSH BUTTON is moved to the middle position (level 5).
The settings should first be tested on a specimen. If the
welding result is not satisfactory, the wire feed can be
readjusted to plus or minus. It should be noted that the
wire feed is adjusted to each switching stage at the ope-
rating point setting. Using wire feed and welding voltage,
you can set the arc individually according to the applica-
tion.
Using the ratio voltage to current or voltage to wire feed
speed I can reach different arc lengths, which are used
for different applications. The main three types are exp-
lained later in this guide.
Setting aid:
The new adjustment aid makes it easier for the welder to
adjust the welding device. When selecting wire feed
speed level 5, the wire speed does not have to be cor-
rected for changes in the voltage levels (= welding cur-
rent), or only to a limited extent, since the device auto-
matically sets the optimum wire feed speed.
9.5 Preparation of the weld
The weld joint describes the weld and the special posi-
tion of the welded parts to each other. A particular type of
joint requires a corresponding seam type, which is also
determined by the sheet thickness, the seam preparation
(joint shape), the material and the welding process.
Groove shapes
The workpieces to be welded should be free of color, me-
tallic coatings, dirt, rust, grease and moisture in the seam
area. The welding preparation is to be carried out in accor-
dance with the welding regulations dseam planning.

Seam planning
9.6 Performing welds
To start welding, bring the torch to the workpiece and
press the torch button. The wire feed unit is activated
and conveys the current-carrying wire electrode from the
nozzle. The gas starts to flow out of the burner. If the
wire touches the workpiece, a short circuit occurs and
the arc is created.
Burner management
The inclination of the burner to the weld should not ex-
ceed approx. 70 °. The distance between the burner and
the workpiece should be approx. 10 - 12 x wire diameter
[mm]. It can be welded piercing or towing.
Towing welding:
The burner is pulled. Deep penetration, narrow seam.
The power of the bow prevents slag from entering the
molten bath.
Piercing welding:
The burner is pushed. Flat penetration, wide seam pat-
tern. Good suitability for welding thin sheets, low distor-
tion due to lower heat input.
Inclination of the burner
The angle between burner and workpiece affects the
shape of the weld and the penetration depth. The follo-
wing pictures show how the inclination of the burner
should be kept on the seam.

EASY-MAG-Series | Version 2.01 19
Operation
Influence of wire feed change on operating point and arc length.
The arc length is set via the ratio of welding voltage to
welding current.
9.7 Description and use of different arc types
The short arc (KLB) is used for thin sheets, forced and root
welds in the low power range. The material transfer
takes place with little spatter formation in the short cir-
cuit.
The transitional arc (ÜLB) is preferred for medium power in
MAG welding of medium plate thicknesses un argon mi-
xed gases. The material transfer is coarse droplet, partly
in short circuit - but with less spatter than in LLB (long
arc) under carbon dioxide.
The spray arc (SLB) allows high melting rates and higher
welding speeds with larger wall thicknesses under argon
mixed gases.The material transfer is fine droplet without
short circuits and is very low spatter.
In long arc (LLB), high wall thicknesses are MAG-welded
under high-performance carbon dioxide. The material
transfer is coarse droplets and splashy. That is why this
type of arc is only used in a few cases.
Guide values for arc types and applications depending on wire
diameter
9.8 Selection of wire electrode and inert gas
With the MIG / MAG process, various materials such as
alloyed and unalloyed steels, stainless steels and alu-
minum welding. The welding system must be retrofitted
accordingly and equipped with the right components
such as filler material and gas.
Additional material
The filler material is selected based on the base material
to be welded and the desired weld seam quality. The
wire thickness is chosen according to the thickness of
the sheet, the shape of the joint and the required welding
current.
Protective Gas
The protective gas has the task to shield the molten bath
from the atmosphere. It influences the electrical conducti-
vity, the heat conduction and the heat content of the arc.
In addition, the shielding gas also influences the chemical
composition of the resulting weld metal due to ignition and
burnup processes. The shielding gas also determines the
welding process. Steel materials are usually an MAG
process (metal-active gas) that uses mixed gases that re-
act with the molten bath, ie are active. For welding alu-
minum, for example, pure argon is used. Argon is an inac-
tive gas and does not react with the molten bath. There-
fore, the welding of aluminum is a MIG (Metal Inert * Gas)
process.

Maintenance
10 Maintenance
10.1 Scheduled maintenance
Before maintenance work, the welding system must be
switched off and disconnected from the mains and secu-
red against unintentional restart. Supply lines must be
shut off and depressurised. The welding system and its
components are to be maintained according to the main-
tenance chart. Inadequate or improper maintenance or
service may cause malfunction. Regular maintenance of
the system is therefore essential. No structural changes
or additions may be made to the system.
The feed roller, the counterpressure roller and the inlet
nozzle must be regularly checked for contamination and,
if necessary, cleaned. At reasonable intervals, the entire
torch hose package should be cleaned because abra-
sion and dust settled inside.
The contact nozzle of the burner is a wearing part. If the
hole has become too big, it must be replaced. In the in-
ner walls of the plug gas cap of the burner to set metal
splashes. These may need to be removed. A release
agent facilitates the work and prevents the sticking of the
new splashes. Damaged cables must be replaced imme-
diately.
If the welding machine is used in a dusty environment,
the inside of the device must be cleaned at regular inter-
vals by blowing out or sucking it out. The frequency of
this cleaning depends on the respective conditions of
use, but it should be carried out at least twice a year. Use
only clean, dry air to blow out the device or use a va-
cuum cleaner. Avoid direct blowing of electronic compo-
nents from a short distance to avoid damage.
Maintenance intervals
The maintenance intervals are a recommendation under
normal standard requirements (for example, single-shift
operation, use in clean and dry environment). The exact
intervals are set by your security officer.
ATTENTION!
Before starting maintenance work, make sure that
the welding machine is switched off and dis-
connected from the mains.
