Inserting Electrode Wire into Welding
Gun
Turn the welding machine off.
Depending on welding process, connect the proper
gun to the euro socket, the rated parameters of the
gun and of the welding machine should be matched.
Remote the nozzle from the gun and contact tip or
protection cap and contact tip. Next, straighten the gun
out flat.
Insert the wire through the guide tube, over the roller
and guide tube of Euro Socket into liner of gun. The
wire can be pushed into the liner manually for a few
centimeters, and should feed easily and without any
force.
WARNING
If force is required it is likely that the wire has missed the
liner of gun.
Turn the welding machine on.
Depress the gun trigger to feed the wire through the
gun liner until the wire comes out of the threaded end.
Or the Cold Inch / Gas Purge Switch [26] can be used
– keep in "Cold Inch" position until the wire comes out
of the threaded end.
When trigger or the Cold Inch / Gas Purge Switch [20]
is released spool of wire should not unwind.
Adjust wire spool brake accordingly.
Turn the welding machine off.
Install a proper contact tip.
Depending on the welding process and the type of the
gun, install the nozzle (GMAW process, FCAW-GS
process) or protection cap (FCAW-SS process).
WARNING
Take precaution to keep eyes and hands away from the
end of the gun while the wire is being come out of the
threated end.
Changing Driving Rolls
CITOSTEP 355C is equipped with drive roll V1.0/V1.2
for steel wire. For others wire sizes, is available the
proper drive rolls kit (see "Accessories" chapter) and
follow instructions:
Turn the welding machine off.
WARNING
Turn the input power off of the welding power source
before installation or changing drive rolls.
Release the pressure roll levers [45].
Unscrew the fastening caps [46].
Open the protection cover [47].
Change the drive rolls [48] with the compatible ones
corresponding to the used wire.
WARNING
Be sure that the gun liner and contact tip are also sized to
match the selected wire size.
WARNING
For wires with the diameter larger than 1.6mm, the
following parts are to be changed:
The guide tube of the feeding console [49] and [50].
The guide tube of the Euro Socket [51].
English
Replace and tighten the protection cover [47] to the
drive rolls.
Screw fastening caps [46].
Manually feed the wire from the wire reel, the wire
through the guide tube, over the roller and guide tube
of Euro Socket into liner of gun.
Lock the pressure roll levers [45].
Gas Connection
Connect the gas hose to the Gas Connector [10]
located on the rear panel of the machine.
Put the gas cylinder on the machine shelf and secure
it with the chain.
A gas cylinder must be installed with a proper flow
regulator.
Once a gas cylinder with a flow regulator has been
securely installed, connect the gas hose to the
regulator using the hose clamp.
The welding machine supports all suitable shielding gases
at a maximum pressure of 5,0 Bar.
Always fasten gas cylinder properly in vertical position in a
special holder on the wall or on a carriage. Remember to
close gas cylinder valve after having finished welding.
Welding GMAW, FCAW-GS, FCAW-SS
Process
CITOSTEP 355C can be used to welding GMAW, FCAW-
GS and FCAW-SS process in Manual Mode.
CITOSTEP 355C have been provided with synergic
GMAW and FCAW-GS process.
CITOSTEP 355C do not include the gun necessary for
GMAW, FCAW-GS or FCAW-SS welding. Depending on
the welding process can be purchased separately (see
"Accessories" chapter).
Preparation the Machine for Welding
GMAW, FCAW-GS and FCAW-SS
Process.
Procedure of begin welding of GMAW, FCAW-GS or
FCAW-SS process:
Turn the machine off.
Place the machine conveniently near the work area in
a location to minimize exposure to weld spatter and to
avoid sharp bends in the gun cable.
Determine the wire polarity for the wire to be used.
Consult the wire data for this information. If it is
necessary, change polarity. See [19] point – Terminal
Block of Changing Polarity
Connect output the gun to GMAW, FCAW-GS or
FCAW-SS process to Euro Socket [6].
Connect the work lead [13] to output socket [7] or [8].
Connect the work lead to the welding piece with the
work clamp.
Install the proper wire.
Install the proper drive rolls.
Manually push the wire into the gun's liner.
Turn the machine on.
Insert the wire into the welding gun.
Keep the gun cable as straight as possible when loading
electrode through cable.
