, stretch torch cable and 

press buttons 

22

 on operating panel. Adjust the pressure at 

the modulation screws 

20

 that the wire-feed rolls 

19

 even still 

are turning by holding the wire coil. The wire should not be 
clamped or deformed.

Hold down button 

22

 until wire projects about 20 mm from 

torch neck.

Screw in the contact tip corresponding to the wirediameter 
into the torch

 and cut off the sticked out wire end.

How to connect the gas cylinder

Before opening the bottle the adjustment 
screw 28 at the housing must be relieved, it 
means, turned to the left, otherwise the 
pressure-reducing vale could be damaged.

Put the gas cylinder 

2

 on the provided place at the back of the 

machine and protect against falling by fastening the chain 

27

.

Open the gas valve 

26

 several times to blow out possible dirt 

particles.

Turn the adjustment screw 

28

 of the pressure reducer 

1

 com-

pletely to the left.

Connect the pressure reducer 

1

 at the gas cylinder 

2

.

Connect the gas hose 

23

 at the pressure reducer. Open the 

gascylinder and adjust the gas flow at the set screw 

28

 of the 

pressure reducer while pressing the torch button. 

The quantity will be shown at the flowmeter 

24

. This should 

be approx. wire diameter x 10 l/min. The content of the cylin-
der is shown by the contentmanometer 

25

.

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 

33

 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.
