Replacing and inserting wire

S
Open the side panel.
S
Place the spool on the hub and secure it with the lock.
S
Disconnect the pressure arm by folding it sidewards, the pressure roller slides
away.
S
Straighten out the new wire 10-20 cm. File away burrs and sharp edges from the
end of the wire before inserting it into the wire feeder.
S
Make sure that the wire goes properly into the feed roller groove and into the
outlet nozzle and the wire liner.
S
Secure the pressure arm.
S
Close the side panel.
Feed the wire through the welding gun until it comes out through the nozzle. This
operation should be carried out carefully, as the wire is ready for welding and an
unintentional arc may occur. Keep the gun off conducting parts during feeding the
wire through and terminate wire feeding instantly when the wire comes out.
See Technical Data, chapter
∅
Use only 200mm spools. Note!
WARNING!
Do not keep the welding gun near the ears or the face during the wire feeding,
as this may result in personal injury.

you want to use it for
1. Fold back the pressure arm to release the pressure roller.
2. Switch on the power source and press the gun trigger to position the feed roller
so that the locking screw is visible.
3. Switch off the power source.
4. Use a 2mm Allen key to open the locking screw about half a turn.
5. Pull the feed roller off the shaft and turn it around. See marking on the side of the
feed roller for suitable wire diameters.
6. Put the roller back on the shaft and make sure it goes all the way in. You may
need to turn the roller to position the locking screw over the flat surface of the
shaft.
7. Tighten the locking screw.

Shielding gas

A mixture of carbon dioxide and argon or pure carbon dioxide can be used as
shielding gases.

Overheating protection

Overheating is indicated by lamp (3). A thermal overload fuse protects the unit against
overheating by disabling the welding if overheating occurs. The fuse resets automati­
cally when the unit has cooled.
