3. OPERATION
3.1 General notes
•
The device must be applied according to its purpose, with observance of OHS regulations and
restrictions resulting from data included in the rating plate (IP level, operation cycle, supply voltage,
etc.).
•
The machine must not be opened as it will cause warranty loss and, in addition, exploding, not shielded
elements can cause serious injuries.
•
The producer does not bear any responsibility for technical changes in the device or material losses
caused by the introduction of the said changes.
•
In case of incorrect device operation, contact the service centre.
•
Louvers must not be shielded - the welder must be positioned at 30 m distance from objects
surrounding it.
•
The welder must not be kept under your arm or near to your body.
•
The machine must not be installed in the rooms with aggressive environment, high dustiness and near
devices with high electromagnetic field emission.
3.2 Device storage
•
The machine must be protected against water and moisture.
•
The welder must not be positioned on heated surfaces.
•
The device must be stored in a dry and clean room.
3.3 Connecting the device
The Omega welder can be operated with a feeder that is directly placed on the welder or in a distanced
position from it. Depending on the operation type, the proper conduit connecting the feeder with the
welder must be chosen. In case of a model with the feeder placed on the welder, a 1 m long conduit should
be used, for free work with a feeder in a remote position from the welder - 10 m long conduit. In order
to place the feeder on the welder, it must be mounted on the pin located on the top part of the welder.
This solution eliminates the danger of the feeder falling from the welder. Concurrently it can rotate which
increases the field of operation. The conduit connecting the feeder with the welder must be connected to
proper sockets (the sockets described below). Power and control terminals have different shapes, preventing
incorrect connection; the cooling circuit has an inlet/outlet marked with colours.
3.3.1 Connecting the power
•
Connection of the device must be performed by a qualified person. In addition, a person with required
qualifications should check if the earthing or electrical installation with protection system is in line with
the safety regulations and if they operate correctly.
•
The device must be placed near the work station.
•
Connection of excessively long conduits to the machine must be avoided.
•
One-phase welders should be connected to the socket fitted with an earthing prong.
•
Welders powered from a 3-Phase network are delivered without a plug, the plug must be obtained
independently and installation can be assigned to a qualified person.
PLEASE NOTE! ONLY UPON CONNECTION TO INSTALLATION WITH THE OPERATING SAFETY
DEVICE THE DEVICE CAN BE USED
3.3.2 Connecting gas
•
Gas tanks must be placed far from the welded object and be protected against collapse.
•
Gas connector of the welder must be connected with the tank or gas installation by means of the
correct pipe and regulator with gas flow regulation. Please note! Connection of line regulators to the
tank and the other way round is prohibited. Such a change can result in regulator damage and serious
injuries.
•
Economical gas use extends the welding time.
3.3.3 Welding conduit connection
•
Power pin of the welding handle must be connected to the device.
•
Gas conduit and, alternatively, the conduits of cooling circuit from a welding MIG/MAG torch must be
connected to proper connectors.
•
The chassis ground conduit must be connected to the device and a chassis ground clamp must be
mounted on the welded object.

•
Controlling conduit must be connected to the proper device socket.
•
Welding conduits must be put in possibly parallel position and close to each other.
•
If a connecting conduit, longer than 10 m, connecting the feeder with the welder, is used, then, its length
must be compensated with a parameter 913 (description in the further part of the instruction).
3.3.4 Wire installation
Depending on the type and thickness of the welded material, proper reels, guides and electrode wire must
be chosen. A table, according to which the wire diameters are chosen, is included in the further part of the
instruction.
In case of aluminium welding, type U reels must be used, placed in the unit feeding the wire and the Teflon
electrode wire guide must be placed in the conduit of the welding handle. In addition, it is necessary to use
the special contact tips for aluminium. All these elements are chosen so that they match the wire diameter.
In order to weld steel, it is necessary to have reels of type V, spiral guide and contact tips for steel. In addition,
all these elements are chosen in a similar manner as in the case of aluminium welding - according to the
wire diameter.
Upon properly equipping the half-automat and welding torch, the torch must be connected to the feeder,
wire reels must be mounted and the wire must be fed to the welding torch.
In order to mount the wire, you must:
•
Place the reels in the feeder, depending on the size and type of the reel, it may be necessary to use the
proper adapter.
•
Open the arms of pressure rolls.
•
Draw the wire through the feeding unit and insert its tip into the guiding tube welding torch socket
collet.
•
Block pressure rolls.
•
Start the machine
•
Select MIG or MIG PULSE operation mode.
•
Set the roll pressure and reel brake.
•
Press the button "WIRE INCH" on the welder panel until the wire appears in the contact tip of the
torch.
In order to regulate the roll pressure, you must:
•
Decrease the pressure to a minimum.
•
Pick the wire between the reel and the feeding unit with your fingers.
•
Turn on the wire feeder (button "WIRE INCH").
•
If it is possible to stop the wire with fingers, the pressure of the first roll must be increased.
•
Put the wire feeder into operation (button "WIRE INCH") and check if the wire can be stopped.
•
Repeat this action until it is not possible to stop the wire any longer.
•
Upon reaching the pressure level which makes it impossible to stop the wire, the regulatory knob must
be tightened by half of a rotation and the pressure must be set on the second pair of rolls, according to
the position of the first knob, but with slightly lower pressure.
In order to regulate the braking level of the reel, you must:
•
Loosen the pressure screw of the brake.
•
When turning wire feeding on and off, you must increase the screw pressure so that the inert reel
rotation, upon feeder shut down, is from 10⁰ to 20⁰.
