Process
CITOSTEP 255C & 305C can be used to welding GMAW,
FCAW-GS and FCAW-SS process in Manual Mode.
CITOSTEP 255C & 305C 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
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 [17] point – Terminal
Block of Changing Polarity.

Connect output the gun to GMAW, FCAW-GS or
FCAW-SS process to Euro Socket [6].

Make a sure, if it is needed (GMAW, FCAW-GS
process), that the gas shield has been connected.

Connect the work lead 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 roll.

Manually push the wire into the gun's liner.

Turn the machine on.

Insert the wire into the welding gun.
WARNING
Keep the gun cable as straight as possible when loading
electrode through cable.
WARNING
Never use defected gun.

Check gas flow with Gas Purge Switch [18] – GMAW
and FCAW-GS process.

Close the right side panel.

The welding machine is now ready to weld.
WARNING
The right side panel has to be completely closed during
welding.
WARNING
Keep the gun cable as straight as possible when welding
or loading electrode through cable.
WARNING
Do not kink or pull cable around sharp corners.
