Recommendation
Keep a complete set of welding bars in stock. This means that they can be changed whenever
necessary without interrupting production too much! Send the used set of welding bars to the
VC999 Customer Service Department to be reconditioned.
Removing welding bars
§ Turn the two locking levers on the outside of the welding bars down through 90°. This unlocks the
bars.
§ Pull the welding bars out downwards.
Replacing the Teflon strip
§ In order to remove the Teflon strip, peel off the
glass-fibre adhesive tape on either side (1).
§ Dispose of the glass-fibre adhesive tape.
§ Dispose of the used Teflon strip (2).
§ Clean the welding bar (3) with acetone. Ensure
that the room is well ventilated.

CAUTION
Acetone is highly inflammable! No smoking and no naked flames!
§ If you find that the welding and cutting wire is no
longer taut enough when you change the Teflon
strip, they must be replaced. The procedure is
described in the next section.
§ Apply the new Teflon strip (2) tightly, leaving no
creases, and also rub it with a clean cloth.
§ Also attach the Teflon strip (2) to the side of the
welding bar (3) using the glass-fibre adhesive
tape (1).
