9. Replacing the welding wire
CAUTION! All maintenance, replacement of parts, repairs or adjustments should be carried out with
the power supply disconnected from the device.
1. Open the spool housing by pressing the opening buttons and install the spool so that it
rotates counterclockwise.
2. Secure the spool with the spool lock.
3. Unfasten the end of the wire from the spool and hold it in your hand at all times to prevent
the spool from unwinding.
4. Straighten the end of the wire for about 20 cm and cut off the bent part.
5. Open the pressure adjustment lever that opens the feeding mechanism.
6. Guide the wire through the rear wire guide to the welding gun wire guide.
7. Close the feeding mechanism and secure it with the pressure adjustment lever. Make sure
that the wire runs in the groove of the drive roll.
8. Adjust the pressure of the lever, but do not exceed half of the scale. Too much pressure can
damage the wire. On the other hand, if the pressure is too weak, the wire will slide in the
feed mechanism and the wire will not move smoothly.
9. Make sure that the contact tip suitable for the installed welding wire is inserted into the
welding gun. If necessary, replace the contact tip.
10. Press the trigger of the welding gun and wait for the wire to come out.
CAUTION! Getting the wire out of the burner requires applying power to the unit. Do not
touch any earthed objects with the torch; otherwise, an electric arc may form.
11. Close the spool housing cover.
CAUTION! When inserting the wire into the gun, do not point the gun at yourself or at other people.
Do not place your hand, e.g., in front of the tip, as the cut end of the wire is very sharp. Also, keep
your fingers away from the feed roller, as this may cause your fingers to be pinched between the
rollers.
10. Disposal of the packaging
Please keep all packaging material (cardboard, plastic strips and polystyrene foam) to ensure that the
unit is protected during shipment, should it become necessary to send it to a service center!
11. Transport and storage
When transporting the unit, protect it from shocks and tipping over, and do not place it "upside
down". Store the unit in a well-ventilated room where dry air is present and corrosive gases are not
present.
12. Cleaning and maintenance
• Before each cleaning, and also when the device is not in use, disconnect the power plug and
let the device cool down completely.
• Remove the spatter from the tip of the welding gun and check the condition of the parts.
Damaged parts must be replaced immediately.
• Use only non-corrosive cleaning agents for cleaning surfaces.
• Do not spray the unit with a stream of water or immerse it in water.
• Make sure that no water enters through the ventilation openings in the casing.
• Clean the ventilation openings with a brush and compressed air.
• After each cleaning, all the parts should be dried well before the unit is used again.
• Store the unit in a dry and cool place protected from moisture and direct sunlight.
