Connection and start-up
Preparation for welding
Before commissioning, make sure that the liner that
matches the wire is inserted. Please replace if necessary. The
wire guide must also fit.
Introducing wire
Lay out the intermediate
drive with stretched hose
as straight as possible.
Open the intermediate
drive in order to observe
the correct wire feeding
process. Place the wire
reel in the feeding device
of your welding source.
Deburr the cut welding wire with emery cloth or file. If the
wire is deburred and reasonably straight, it will thread itself.
In case of a fault, stop and insert the wire by hand into the
wire guide.
Opening/closing the pressure arm
The wire can be extended in idle mode. In special cases you
can open/close the pressure arm (dark grey) manually. To
do so, open the housing, unlock the bayonet and pull the
slider back.

To open lift the pressure arm (dark grey) at position [1] with
a slotted screwdriver. To close, press the pressure arm down
until it locks into place.
Changing the feed roller
Open the pressure arm. Open the fastening screw [1].
Remove the driving sprocket, then pull the feed roller [4]
from the sprocket [3]. Then replace the feed roller and
reassemble in reverse order.

Exchanging the wire guide
Open the Allen screw [1]. Replace the wire guide [2]. For
exact positioning, make sure that the notch [3] is positioned
under the Allen screw. Then carefully tighten the Allen
screw again.

Exchanging the wire liner
Plastic wire guides with wire spiral attachment, can be
used for aluminium, copper, nickel and stainless steel wires.
Lay the hose pack out straight. Then loosen the union nut
(grey) with a size 12 open-end wrench and remove it.
After removing the union nut the nipple of the wire guide
spiral becomes visible. Use the same to pull the wire guide
spiral out of the hose pack.
There are wire guide spirals with firmly pressed nipples and
wire guide spirals with clamping nipples. If the nipple is not
already firmly pressed, push it onto the wire guide spiral.
Then insert the new wire guide spiral into the hose pack
and measure the length that protrudes from the central
adapter to the O-ring on the nipple.
Pull out the wire guide spiral again and cut off the
measured length -1 cm, the cut edge must be deburred.
Push the wire guide spiral back in and tighten the union
nut again hand-tight with the open-end wrench.
