5. Before starting the equipment

5.1 Assembly (Fig. 5-21)
5.1.1 Installing the castors and guide rollers (6/8)
Install the castors (6) and guide rollers (8) as shown
in Figures 7, 9, 10 and 11.
5.2 Gas connection (Fig. 4-6, 19-25)
5.2.1 Gas types
Gas shielding is required for welding with continuous
wire, the composition of the shielding gas depends
on the welding method you wish to use.
Shielding gas
Metal to be welded
Non-alloyed steel
5.2.2 Fitting the gas bottle on the unit (Fig. 19-25)
The gas bottle is not supplied.
Fit the gas bottle cables as shown in Figures 19 - 21.
Ensure that the safety chain (28) is secure and that
the welding set cannot tip over.
Important. Only gas bottles with a maximum capacity
of 20 liters may be fitted 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) 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 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 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.
CO2 Argon/CO2
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 shock-proof sockets.
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 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
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.
