2.5.2 Feeding in the welding wire
NOTE! Remember to remove the sharp cut tip of the filler wire before loading the wire to the
welding gun, so preventing damage to the liner inside the welding gun cable. This is particularly
important for soft filler wires such as aluminium. It will also improve feed quality and increase the
service life of your gun liner.
For reliable performance only use Kemppi gun liner materials specially developed for use with
Kemppi machines.
For information on recommended liners and wire feed rolls selection, please see the relevant
sections later in this chapter. Be careful not to let the wire unwind from the spool.
NOTE! When feeding the welding wire into the gun, be sure that you are not pointing the gun at
anyone and that there isn’t anything in front of the gun.
to feed the wire from the spool to the welding gun:
1. Open the pressure arm of the GT02 mechanism and lift the top roll clear on its pivot.
2. Draw some loose wire from the spool and carefully push it through the bronze wire
guide at the back of the mechanism. Push the wire over the feed roll groove and through
the front wire guide until it comes out from the Euro connector by about 150mm.
3. Replace the top feed roll over the wire and close the pressure arm.
4. Cut away any deformed wire section and dress the sharp wire tip as described above.
5. Connect the welding gun and tighten the collar.
6. Press the welding gun trigger and allow the filler wire to feed through the gun cable to
the contact tip.
Check once again that the wire is still properly in the grooves of both feed roll pairs. Now the
FitWeld Evo is ready to weld.
