Installation and regulation of machine
elements
Before carrying out any works on the machine it
must be disconnected from the mains.
Do not draw up the fastening ele-
ments too tight to avoid damaging the
thread.
Mounting / dismounting / setting-up of
some elements is the same for all ma-
chine models, in this case specific mod-
els are not indicated in the illustration.
Mounting / dismounting of a plug, current-carrying
cable, stationary network connection
Some machine models are supplied without plugs
and / or current-carrying cables - they must be installed
before the beginning of the operation�
Machines can also be connected to the network on a
stationary basis (not through a socket)�
Note: the stationary connection of the
machine to the network as well as instal-
lation or replacement of current-carrying
cables, plugs and other electrical units
must be performed only by a qualified electrician or
circuit installer authorized to perform such works.
Connection to the earthing loop (see fig. 1)
Using grounding bolt 3 connect one grounding wire
clamp 51 to the machine (see fig. 1). Connect the sec-
ond grounding wire clamp 51 to the working grounding
loop�
Gas connection (see fig. 2)
• Install a gas pressure regulator 53 on a gas cylin-
der 55 (see fig. 2). Attention: flow rate meter flask
should be installed vertically upward.
• Put clamps 52 on the ends of hose 54� Connect one
end of the hose 54 to a connection pipe of the gas
pressure regulator 53, the other one - to the connec-
tion pipe 4� Fix the hose 54 on connection pipes by
clamps 52�
Connecting / disconnecting welding cables (see
fig. 3-5)
During TIG welding (see fig. 3-4)
• If necessary to attach the connector to the welding
cable, follow the steps shown in fig. 3.1, 4.1.
• If electrode holder 40 is installed, disconnect it�
• Connect earth clamp 41 (see fig. 3.2, 4.2) to the ma-
chine�
• Connect the welding torch 42 to the machine:
• connect a welding torch control cable� Set a con-
trol cable connector in socket 6 and tighten a nut 58
by hand� During installation, pay attention that locat-
ing tab inside of a socket fits a location slot of the
cable connector (see fig. 3.3, 4.3);
