5.2.2 Fitting the gas bottle on the unit
(Fig. 22-23)
The gas bottle is not supplied.
Fit the gas bottle as shown in Figures 22 – 23. En-
sure that the belt strap (15) is secure and that the
welding set cannot tip over.
Danger! Only gas bottles with a maximum ca-
pacity of 10 liters may be fi tted on the gas bottle
support area (Fig. 23/5). If you wish to use larger
gas bottles, there is a risk that they will tip over
and therefore they may only be placed next to the
unit. In this case the gas bottle must be secured
to prevent it tipping over.
5.2.3 Connecting the gas bottle (Fig. 7, 24-27)
After removing the protective cap (Fig. 24/A),
open the bottle valve (Fig. 24/B) briefl y, ensuring it
is pointing away from your body.
Clean any dirt off the connecting thread (Fig.
24/C) if necessary using a dry cloth without ad-
ding any cleaning products. Check whether there
is a seal on the pressure reducer (19) and that it
is in perfect condition. Turn the pressure reducer
(19) clockwise on to the connection thread (Fig.
25/C) on the gas bottle (Fig. 25). Place the two
hose clips (j) over the shielding gas hose (18).
Connect the shielding gas hose (18) to the shiel-
ding gas hose connection (23) on the pressure
reducer (19) and gas supply connector (16) on
the welding set and secure it to both connectors
using the hose clips (j). (Fig. 26-27)
Important. Check all gas and other connection for
leaks. Check the connections using leak spray or
soap suds.
5.2.4 Information about the pressure reducer
(Fig. 4/19)
The gas delivery rate can be adjusted using the
rotary knob (24). The set gas delivery rate can be
read off the pressure gage (20) in liters per minu-
te (l/min). The gas is discharged at the shielding
gas hose connector (23) and is then forwarded
to the welding set through the shielding gas hose
(Fig. 3/18). (see 5.2.3)
Important. Always proceed as described in point
6.1.3 for setting the gas delivery rate.
The pressure reducer is fi tted on the gas bottle
using the screw connector (21) (see 5.2.3).
Danger! The pressure reducer may only be
adjusted and repaired by trained personnel.
GB
Send defective pressure reducers to the service
address if necessary.
5.3 Mains connection
•
Before you connect the equipment to the
mains supply make sure that the data on the
rating plate are identical to the mains data.
•
The equipment may only be operated from
properly earthed and fused shock-proof so-
ckets.
5.4 Fitting the wire spool (Fig. 1, 5, 6, 28 – 36)
The wire spool is not supplied.
5.4.1 Wire types
Various welding wires are required for diff erent
applications. The welding set can be used with
welding wires with a diameter of 0.6 and 0.8 mm.
The appropriate feed rollers and contact tubes
are supplied with the set. The feed roller, contact
tube and wire cross-section must always match
each other.
5.4.2 Wire spool capacity
Wire spools with a maximum weight of 5 kg can
be fi tted in the welding set.
5.4.3 Inserting the wire spool
•
Open the housing cover (Fig. 1/4)
•
Check that the windings on the spool do not
overlap so as to ensure that the wire can be
unwound evenly.

Inserting the wire spool (Fig. 28, 29)
Place the wire spool (N) on the spool holder (B).
Ensure that the end of the welding wire is unw-
ound on the side of the wire guide, see arrow.
Ensure that the spool lock (A) is pushed in and
