2.8 Installing and replacing wire guide tubes
The wire feed mechanism includes three wire guide tubes. Replace them when the filler wire diameter or material
changes. Select the wire guide tubes according to the tables in "Wire feeder consumables" on page88.
When replacing the outlet guide tube, the welding gun must be detached.
a. Inlet guide tube
b. Middle guide tube
c. Outlet guide tube
To replace the wire guide tubes:
1. Release the pressure arms and remove the filler wire from the system.
2. Pull out the inlet guide tube (a) and insert a new one in its place.
3. Turn the locking clip aside to free the middle guide tube (b) for replacement.
4. Insert a new middle guide tube in its slot and push it properly in place. Ensure that the mark arrow points to the
wire running direction.
5. Turn the locking clip back to lock down the new middle tube.
6. Replace the outlet guide tube (c) by pushing the old outlet tube out from either direction.
