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) briefly, 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 adding 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 shielding 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)
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 pressure gage (31) shows the bottle pressure 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 fitted on the gas bottle using
the screw connector (21) (see 5.2.3).
Important. 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 fire,
an electric shock and personal injury:
Never use the welding set with a rated voltage 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 different
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
fitted 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.
