Important - Migatronic OMEGA 180 Manuel D'instruction

Lift instructions
The lifting points at the OMEGA sack barrow can be
used for lifting with a crane (figure 1).
The OMEGA trolley with 4 wheels can only be lifted
manually by lifting it in the handle (figure 2).
The machine must not be lifted with mounted gas
bottle!

Important!

In order to avoid damage to plugs and
cables, good electric
required when connecting the work
return cable and welding torch to the
machine.
Connection of shielding gas
The shielding gas hose is fitted to the back panel of
the power source (3) and is connected to a gas supply
with a pressure reduction to 2-6 bar. One gas cylinder
can be mounted on the bottle carrier on the back of a
trolley if any.
Connection of torch for MIG/MAG welding
The welding hose assembly is pushed into the central
connector coupling (4) and the nut (5) is tightened by
hand. The return lead is connected to the negative
pole (6).

Torch adjustment (Dialog torch)
The current size can be adjusted both from the
machine and the welding torch if a welding hose with
dialog torch is in use. This function cannot be
disconnected. The torch adjustment is passive without
Dialog torch.
Inching
The function is used for wire inching e.g. after change
of wire. Wire inching starts by pressing the green key
pad and simultaneously triggering the torch trigger.
Wire inching continues even though the green key pad
has been released. It does not stop until the torch
trigger has been released again. OMEGA 400 has an
additional wire inching key inside the wire chamber.
Selection of welding polarity
(OMEGA MINI/OMEGA 400)
We recommend that you shift welding polarity for
certain types of welding wire, and this especially as
regards Inner shield welding wire. Please control the
recommended polarity stated on the packing of the
welding wire.
OMEGA MINI
Change of polarity
1. Disconnect the machine from the mains supply.
2. Use a wrench to dismount the bolts and discs at
the poles.
3. Reverse the cables.
4. Use a wrench to mount the bolts and discs.
5. Connect the machine to the mains supply.
OMEGA 400
Change of polarity
1. Disconnect the machine from the mains supply.
2. Dismount screws in the wire chamber with a
wrench (picture 1).
3. Exchange brass plate from plus to minus (picture
1)
4. Mount screws in the wire chamber with a wrench
(picture 1)
5. Exchange earth cable from minus to plus (picture
2)
6. Connect the machine to the mains supply.
