•
Depending on the welding process and the type of
the gun, install the nozzle (GMAW 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
WARNING
Turn the input power off of the welding power source
before installation or changing drive rolls.
SPEEDTEC 180C
and
SPEEDTEC 200C
is equipped
with drive roll V0.8/V1.0 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.
•
Release the pressure roll lever [30].
•
Unscrew the fastening cap [29].
•
Change the drive rolls [31] with the compatible ones
corresponding to the used wire.

Gas Connection
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 from the
regulator to the machine gas inlet connector. Refer to
point [17] of the Figure 3.
WARNING
The welding machine supports all suitable shielding
gases including carbon dioxide, argon and helium at a
maximum pressure of 5,0 bars.
Welding GMAW, FCAW-SS Process
SPEEDTEC 180C
and
SPEEDTEC 200C
can be used to
welding GMAW and FCAW-SS process.
SPEEDTEC 200C
has been provided with synergic
GMAW process.
SPEEDTEC 180C
and
SPEEDTEC 200C
does not
include the gun necessary for GMAW or FCAW-SS
welding. Depending on the welding process can be
purchased separately (see "Accessories" chapter).
Preparation the Machine for Welding
GMAW and FCAW-SS Process.
Procedure of begin welding of GMAW or FCAW-SS
process:
•
Determine the wire polarity for the wire to be used.
Consult the wire data for this information.
•
Connect output the gas-cooled gun to GMAW /
FCAW-SS process to Euro Socket [7].
•
Depending on the using wire, connect the work lead
[19] to output socket [8] or [9]. See [25] point –
terminal block of changing polarity.
•
Connect the work lead to the welding piece with the
work clamp.
•
Install the proper wire.
•
Install the proper drive roll.
•
Make a sure, if it is needed (GMAW process), that
the gas shield has been connected.
•
Turn the machine on.
•
Push the gun trigger to feed the wire through the gun
liner until the wire comes out of the threaded end.
•
Install a proper contact tip.
•
Depending on the welding process and the type of
the gun, install the nozzle (GMAW process) or
protection cap (FCAW-SS process).
•
Close the left side panel.
•
The welding machine is now ready to weld.
•
By applying the principle of occupational health and
safety at welding, welding can be begun.

The 2-Step - 4-Step
changes the function of the gun’s
trigger.
•
2 Step trigger operation turns welding on and off in
direct response to the trigger. Welding process is
performed when the gun’s trigger is pulled.
•
4-Step mode allows to continue welding, when the
gun’s trigger is released. To stop welding, the gun’s
trigger is pulled again. 4-step mode facilitates to
making long welds.
WARNING
4-Step does not work during Spot Welding.
