Connection of welding torch
With the machine disconnected from the supply, connect welding torch into
EURO connector (pic. 1A/B, pos. 4). Connect earth cable to gladhand (pic.
1A/B, pos. 5) and tighten it. The welding torch and the earth cable should
be as short as possible, close to each other and positioned at the floor level
or close to it.
Welding part
The part to be welded must always be connected to earth in order to re-
duce electromagnetic radiation. Much attention must be afforded so that
the earth connection of the part to be welded does not increase the risk
of accident to the user or the risk of damage to other electric equipment.

Connection of the welding wire and
adjustment of gas flow
Before connecting the welding wire, it is necessary to check the wire feed
13
rolls if they correspond to the profile of the roll groove. When using the steel
14
welding wire, it is necessary to use the roll with the V-shaped roll groove.
15
Changing of wire feed roll
Rolls are two-grooved. These grooves are designed for two different diame-
17
ter of the wire (e.g. 0.8 and 1.0 mm).
18
• lift the holding-down mechanism
19
• if there is a suitable groove on the roll, turn the roll and put it back on the
shaft and secure it with a plastic locking screw

Connection of welding wire
• Take off the side cover of wire container.
22
• Put on the wire spool onto the holder into the container (pic. 2 pos. 11).
• Cut off the end of the wire fastened to the edge of the roller and lead it
into the inlet guide (pic. 2 pos. 12), then through the roll of feed into the
23
draw-in tube (pic. 2 pos. 13) 10 cm at least.
• Check if the wire leads through the right feed groove.
• Tilt the holding-down roll down and return the holding-down mechanism
into the vertical level.
• Adjust the nut pressure of thrust to secure the wire feed without pro-
blems and deformation by too much thrust.
• Dismount the gas tip of the welding torch.
• Unscrew the flow drawing tip.
• Connect the socket plug into the network.
• Turn on the main switch into position 1.
• Press the wire feed button - for STANDARD torch button, for PROC./SYN.
on the control panel
• The welding wire is lead into the torch. The speed of the leading-in must
be adjusted with the potentiometer with the speed of the wire feed (pic.
1A/B pos. 6).
• After the run of wire from the torch, screw the flow drawing tie and the
gas tube.
• Before welding use anti-spatter spray in space of the gas tube and the
flow drawing tie. In that way you prevent adherence of metal spatter and
prolong the life of the gas tube.

WARNING! During wire threading don't aim the torch against eyes! Be ca-
reful when manipulating the wire feed because of possible injury of a hand
with sheaves.
Changes when using aluminium wire
For welding with aluminium wire it is necessary to use a special roll with
„U" profile (chapter spare parts of wire feed and list of sheaves). In order to
avoid problems with „ruffle" of wire, it is necessary to use wire in diameter
min. 1.0 mm from alloys AIMg3 or AIMg5. Wires from alloys A1995 or AlSi5
are too soft and can easily cause problems with feed. For welding of alumini-
um it is necessary to equip the torch with a teflone Bowden and the special
flow drawing tie. As shielding atmosphere it is necessary to use pure Argon.
Adjustment of gas flow
The electric arc and the welding pool must be perfectly protected by the gas.
Too little amount of the gas cannot create necessary shielding atmosphere
and on the contrary, too big amount of gas entrains air into the electric arc,
which makes the weld imperfectly protected.
Proceed as follows:
• fix the gas tube with the filter on the inlet of the gas valve on the back side
of the machine (pic. 2, pos. 8)
• if you use the gas carbon dioxide, it is suitable to plug in the gas heating
(during the flow less than 6 litres/min. the heating is not necessary)
