5.10 Removement or assembly of wire group
As mentioned before, the weld head allows to perform Tig weldings with or without filler wire. In case you intend to per-
form only TIG weldings you may remove the filler wire group in order to reduce dimensions and weight of the weld head.
Hereafter are explained all operations to assemble the wire group on the welding head.
• assemble the front wire group fixing it by means of screw
NOTE: The insulating bushing must not be removed when disassembling the wire unit.
• remove rear tap.
• put into position the wire unit paying attention to:
- the front wire liner must be inserted into the hole on the welding head and pushed through
- connect the electric sockets for feeding the wire motor.
• fix the wire unit to the machine body by means of screws.
• add the wire spool as described before and adjust the front wire nozzle.
5.11 Replacement of the wire liner
This operation is necessary due to the wear of the wire liner itself. The wear depends on the roughness of the wire sur-
face. This operation can be programmed periodically after about 10-15 wire spools. As the cost of the wire liner is very
low it is recommended to forcast the replacement before the liner is actually damaged.
Hereafter will be described the necessary replacement of the wire liner.
5.11.1
Replacement of the front wire liner
Act as follows:
• Cut the wire left on the spool.
• Press the 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.
• Remove the wire nozzle from the support and remove it from the liner.
• Loosen screws disconnect electrical connectors and remove the whole wire unit. This way the front wire liner will be
extracted from the welding head.
• Remove the liner from nozzle.
• With the help of a pencil-sharpener round off the extreme parts of the liner and screw it again on nozzle.
• Proceed as described in 3.10.
5.11.2
Replacement of the rear wire liner
Act as follows:
• Cut the wire left on the spool.
• Press the 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.
• Remove the spool as illustrated in the previous paragraph.
• Unscrew the liner to be replaced from its guiding nozzle.
• Remove nozzle.
• With the help of a pencil-sharpener round off the extreme parts of the liner.
• Screw nozzle on the new liner (the liner is self-threading).
• Place again the new liner in its guiding nozzle.
