device can lead to injuries with a death row! During
operation, capacitors are
charged with electrical voltage in the device. This
voltage is still up to 5
minutes after the power cord is unplugged.
1. Turn the unit off.
2. Disconnect the appliance reliably from the mains: pull
the mains plug!
DANGER
Danger due to improper mains connection!
Incorrect mains connection can lead to persons or
property damage!
• The power cord must be properly connected to the
ground.
• Only operate the appliance at a socket with a
protective grounding conductor.
• If a new mains plug has to be connected, this
installation must only be carried out by a qualified
electrician according to the respective national
laws or national regulations (any phase sequence
for three- phase current generators)!
•
Mains plug, plug and socket must be checked at
regular intervals by an electrician!
DANGER
Incorrect handling of the protective gas bottle can lead to
serious injuries and death!
ATTENTION
Risk of burning at the welding current connection! By
means of non-locking
welding current connections, connections and lines can
be heated and lead to
burns on contact!
• Check welding connections daily and, if necessary,
lock them by turning clockwise.
WARNING
Risk of burning due to improper connection of the
ground terminal!
Color, rust or other contamina tion at the connection point
impede the current fow and
can lead to the heating of components!
WARNING
When working with this unit, please consider proper
protective clothing.
When welding and cutting, the skin and eyes must be
protected from the aggressiv e
radiation.
MMA welding and plasma cutting also involve the risk of
inflammation. Again, skin and eyes must be protected.
MIG/MAG
MIG / MAG welding machine works with a melting
welding wire, which is continuously tracked by means of
a motor. In order to adjust the thrust speed, the amount
of abrading filler material can be adjusted variably by the
user. MIG welding uses inert, non- reactive gases, and
active gases are used in MAG welding. Connect the
pressure regulator to the gas bottle. Then connect the
output connection of the pressure
regulator to the gas input connection on the back side of
the device with the aid of the supplied gas hose. Fix the
hose with the supplied hose clamps.
Connect the plug pin oft the earth cable with the earth
socket on the front oft the device. Place the welding wire
roll on the roll axis. Select the wire guide suitable for the
wire diameter used. Loosen the screw of the wire roll.
Press the wire into the wire guide using the wire guide
tube. Align the wire roll so that the wire is securely fixed.
Make sure that the wire is sufficiently tensioned to
ensure a flowing wire feed.
The wire reel must turn clockwise. To prevent the wire
from slipping, connect the wire to the wire roll.
WARNING
The welding wire can move at high speed. In case of
improper or incomplete wire guidance, the wire may leak
uncontrollably and could result a risk of injury
Inductance
For carrying out the MIG / MAG welding, direct current
sources are used which have a certain adjustable
inductance or current rise rate with a defined current
upper limit. In the case of welding by short arc, where the
filler material is transferred dropwise under short
circuits, the current rise rate and the current level must
be limited in order to be able to ignite on the one hand
and, on the other hand, to achieve a stable material
transition through the current smoothing effect. This
means that the inductance must be relatively high in the
range of low electrical welding capacities. However, it
must not be too hig h, as otherwise good ignition would
worsen the ignition. However, it must not be set low
because the material transfer and the seam formation
deteriorate. The inductance should therefore be relatively
low in the area of high welding capacities. The
inducta nce (inductance) reduces the current rise, which
can lead to the fact that no more detachment by the
impulse is possible. Without a choke, the current in the
short circuit would rise very rapidly up to the maximum
power limit of the current source and due to the extreme
resistance heating at the short-circuit point lead to
welding spatter.
MMA:
Connect the ground cable to the socket l (plus).
Connect the electrode holder
at the bottom left to the marked socket. The trigger
switch at the front is set to MMA.
The power plug is plugged in and the device is switched
on at the main switch (back side)
The welding current knob is used to set the correct
current intensity for the respective welding task. The
welding current can be infinitely variable regulated up to
200 A. The selected welding current is dependent on the
thickness of the material and the material to be
machined, the thickness and composition of the rod
electrode, the welding position in which welding is
performed (flat seam, fillet seam, uphill seam, downhill
seam etc.), and the personal habits of the welder.
