Connection of welding torch
With the machine disconnected from the supply, connect welding torch
into EURO connector (pic. 1A/B, position 7) and tighten well the cap nut.
Connect the grounding cable to the grounding quick coupler (pic. 1A/B, po
-
sition 9A/B) and tighten the ground quick coupler. At the machines series
305/405, appoint the outlet as shown in Table 3 or refer to the „Recommen
-
ded welding parameter setting“ table. Welding torch and 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 emission. 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
rolls if they correspond to the profile of roll groove. When using the steel
welding wire, it is necessary to use the roll with V-shaped roll groove.
Changing of wire feed roll
Rolls are two-grooved. These grooves are designed for two different diame
-
ter of the wire (e.g. 0.8 and 1.0 mm).
• lift the holding-down mechanism
• screw out the locking plastic screw and take out the roll
• 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
• put on the wire spool onto the holder into the container
• cut off the end of the wire fastened to the edge of the roller and lead it
into the loading bowden (pic. 2, pos. 15), then through the roll of feed
into the loading 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
• adjust the welding wire coil brake so that the coil turns freely when the
feed mechanism is switched off. Too tightened brake greatly straps the
feed mechanism and wire may slip in the pulleys and misfeed. The brake
adjusting screw is located under the plastic screw of the bobbin holder
(pic. 5).
• dismount the gas tip of welding torch
• unscrew the flow drawing tip
• connect the socket plug into the network
• turn on the main switch into pos. 1
• press the wire feed button for STANDARD inside the machine (pic. 2, pos.
20), for PROC./SYN. on the control panel
• after the run of wire from the torch, screw the flow drawing tie and gas
tube
• connect the protective gas to the gas valve (pic. 2, pos. 18)
• before welding use anti-spatter spray in the space of gas tube and flow
drawing tie; in that way you prevent adherence of metal spatter and pro
-
long the life of gas tube
