Danger! Only gas bottles with a maximum ca-
pacity of 20 liters may be fi tted on the gas bottle
support area (Fig. 19/5). 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
After removing the protective cap (Fig. 22/A),
open the bottle valve (Fig. 22/B) briefl y, ensuring it
is pointing away from your body.
Clean any dirt off the connecting thread (Fig.
22/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.
23/C) on the gas bottle (Fig. 23). Place the two
hose clips (d) 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 (d). (Fig. 24-25)
Danger! 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 pressure gage (31) shows the bottle pressu-
re in bar. 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 minute (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.
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 sockets.
Please read the following to prevent the risk of
fi re, an electric shock and personal injury:
•
Never use the welding set with a rated volta-
ge of 400 V if it is set to 230 V. Caution: Fire
risk.
•
Disconnect the welding set from the power
supply before you adjust the mains voltage.
•
Do not change the rated voltage whilst the
welding set is operating.
•
Before using the welding set, ensure that the
rated voltage setting is identical to that from
the power source.
Please note:
The welding unit is equipped with a 400 V ~ 16 A
CeCon plug. Use the supplied adapter cable No.
30 to operate the welding unit with 230 V~.
5.4 Fitting the wire spool (Fig. 1, 5, 6, 26 – 34)
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 0.6/0.8 and 1.0
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. 2/4) by pushing
the handle for the housing cover (Fig. 2/27)
backwards and opening the housing cover
(Fig. 2/4).
•
Check that the windings on the spool do not
overlap so as to ensure that the wire can be
unwound evenly.
