Indication for 4 rolls feeding units: Adjust the pressure of the
wire rolls 29 at the side of the inlet nozzle 28 less then at the
side of the central connection 16, this provides that the wire
will be hold correct in the wire-feed unit.
Press the button wire insert
20 mm out of the torchneck.
Screw in the contact tip corresponding to the wirediameter
and cut off the sticked out wire end.

How to connect the gas cylinder

Put the gas cylinder 3 on the provided place at the back of the
machine and protect against falling by fastening the chain 35.
Open the gas valve 34 several times to blow out possible dirt
particles.
Connect the pressure reducer 2 at the gas cylinder 3. Con-
nect the gas hose 31 at the pressure reducer. Open the gas-
cylinder and adjust the gas flow at the set screw 36 of the
pressure reducer while pressing the torch button. The quanti-
ty will be shown at the flowmeter 32. This should be approx.
wire diameter x 10 l/min. The content of the cylinder is shown
by the contentmanometer 33.

How to modify the machine for aluminium
welding
Change the wire roll to a aluminium wire roll.
Change the steel-torch against an aluminiumtorch or resp.
change the wire liner against a teflon liner.
Remove the capillary tube 42 at the central connection.
Cut the teflon liner close to the end of the wire-feeding roll and
pull the brasstube over the teflon liner with the corresponding
length for stabilising it.
Fasten the torch and thread in the wire electrode.
The art.no. of the parts depends on the torch and wire-
diameter. Please see at the torch spare list.
