5.7
Adjustment of the filler wire arrival
The wire arrival group is assembled on the torch support following this way all radial and axial movements. To move the
wire nozzle you just have to untighten the M3 screws on the hinges.
While adjusting the nozzle position you must keep in mind that the wire should pass about 0.5 - 1.0 mm under the
electrode and that the wire arrival should be perpendicular to the tube axis and tangentially to the tube to be welded.
5.8
Replacement of the wire nozzle
It is necessary to replace the wire nozzle when the exit hole has become ovaly due to the wear or if you want to change
the filler wire diameter.
In this way exact guiding of the wire to the welding bath is no longer guaranteed.
Nozzles for wire diameter 0.6 ; 0.8 ; 1.0 mm are available.
For the replacement unscrew screw, extract the nozzle and remove the nozzle from the wire liner.
5.9
Replacement of the wire spool
Act as follows:
• Cut the wire left on the spool.
• Press the wire forward button on the remote control in order to push forward the wire.
• The wire will advance until it has passed the wire feed rollers. Take a pair of pliers and tear the remaining wire out
of the liner.
• Unscrew handle and remove the spool.
• Take a new spool and round off the top of the wire with a file in order to prevent cutting of the Teflon wire liner.
• Remove the wire exit nozzle near the torch.
• Introduce the wire into the guide until it arrives to the wire feed rollers.
• Act on screw in order to adjust the pressure of the rollers for feeding the wire.
• The right pressure is achieved when the wire is feeded regularly and without interruptions.
• Excessive pressure on the rollers will lead to an early wear. In order to adjust the pressure on the rollers it is neces-
sary to act as follows.
• Switch on the welding equipment.
• In case the wire as stopped in front of the rollers which are too closed act on screw in order to open the rollers.
• Press the manual wire button on the remote control and tight screw until the wire starts to be pushed. Now tight
screw half turn. The pressure will be correct now.
• Place the spool on the shaft and put handle on it.
• Push the manual filler wire button until the wire gets out on the top.
• Place again the wire end nozzle on the liner and fix it on its support.
NOTE: The wire group is equipped with a special friction which allows to keep the filler wire tight on the spool.
