7. Connecting the wires
CAUTION! The electrical installation to which the machine would be connected should be equipped
with an overcurrent fuse.
If an extension cord is used, its cross-section should be at least the same as that of the power cord.
CAUTION! Connecting the cables to the device must be done with the power supply disconnected
and the device turned off.
Welding using the MIG/MAG method
1) Insert the welding gun cable plug into the Euro MIG/MAG output socket on the front panel of
the machine and tighten it.
2) Insert the ground wire plug into the terminal marked "-" on the front panel of the welding
machine and tighten it clockwise.
3) Make sure that the correct welding wire is installed in the machine.
4) Connect the shielding gas cylinder with a pressure reducer to the gas inlet on the rear panel
of the machine using a gas hose.
5) Plug the power cord into an electrical outlet and start the machine. After connecting the
mass cable to the workpiece, work can begin.
MMA welding
1) Connect the welding gun cable to the connector marked with a "-" sign and twist the cable
plug to secure the connection.
2) Connect the ground cable to the connector marked with a "+" sign and twist the cable plug to
secure the connection.
Caution! Cable polarity may vary! All polarity information should be described on the
packaging provided by the electrode manufacturer!
3) Plug the power cord into an electrical outlet and start the machine. After connecting the
mass cable to the workpiece, work can begin.
8. Replacing the drive roller groove
CAUTION! All maintenance, replacement of parts, repairs or adjustments should be carried out with
the power supply disconnected from the device.
If you need to change the wire diameter, also replace the drive roller or adjust the position of the
drive roller.
Be aware of the different types of rolls depending on the welding wire used:
Rollers with a "V" groove.
Rollers with a "U" groove.
Rollers with a knurled groove.
The most popular are rollers with a V-shaped groove. Such rollers are designed for the most popular
welding wires. In the case of aluminum wires, rollers with a U-shaped groove are used. This is due to
the fact that the aluminum wire is more prone to crushing, so that the wire does not deform, it is
necessary to use an appropriate roller. A separate narrow group of feeder rollers are knurled rollers
for cored wire (FCAW).
