5. Before starting the equipment

5.1 Assembly (Fig. 5-21)
5.1.1 Installing the castors and guide rollers
(6/14)
Install the castors (6) and guide rollers (14) as
shown in Figures 7, 9, 10 and 11.
5.1.2 Fitting the welding screen (17)
•
Place the welding glass (l) and the transpa-
rent safety glass (m) over it in the frame for
the safety glass (k) (Fig. 12).
•
Press the safety glass retaining pins (q) into
the holes in welding screen frame (s) from the
outside. (Fig. 13)
•
Place the frame for the safety glass (k) with
the welding glass (l) and transparent safety
glass (m) from the inside into the recess in
the welding frame (s), press the safety glass
retaining bushes (n) on to the safety glass
retaining pins (q) until they engage to secure
the frame for the safety glass (k). The transpa-
rent safety glass (m) must be on the outside.
(Fig. 14)
•
Bend the top of the welding screen frame
(s) inwards (Fig. 15/1) and fold down the top
corners (Fig. 15/2) Now bend the outer sides
of the welding screen frame (s) inwards (Fig.
15/3) and connect them by pressing the top
corners and outer sides together. As the retai-
ning pins engage, you should be able to hear
to clear clicks on each side (Fig. 15/4).
•
When the top corners of the welding screen
are connected as shown in Figure 16, place
the screws for the handle (p) from the outside
through the three holes in the welding screen.
(Fig. 17)
•
Turn over the welding screen and place
the handle (r) over the threads on the three
screws for the handle (p). Secure the handle
(r) to the welding screen the three nuts for the
handle (o) (Fig. 18).
5.2 Gas connection (Fig. 4-6, 19-25)
5.2.1 Gas types
Gas shielding is required for welding with conti-
nuous 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.
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.
CO2 Argon/CO2
The pressure reducer is fi tted on the gas bottle
using the screw connector (21) (see 5.2.3).
