Changing Driving Rolls
WARNING
Turn the input power off of the welding power source
before installation or changing drive rolls.
SPEEDTEC 215C 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 [11] of the Figure 2.
WARNING
The welding machine supports all suitable shielding
gases including carbon dioxide, argon and helium at a
maximum pressure of 5,0 bars.
WARNING
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.
WARNING
Gas cylinder can be fasten on the machine’s shelf, but
the height of gas cylinder doesn’t have to be higher than
43in/1,1m. The gas cylinder which is fastened on the
machine’s shelf has to be secured by attaching it to the
machine using the chain.
Welding GMAW, FCAW-SS Process
SPEEDTEC 215C can be used to welding GMAW and
FCAW-SS process. It has been provided with synergic
GMAW process.
SPEEDTEC 215C packaging 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 [4].

Depending on the using wire, connect the work lead
[19] to output socket [5] or [6]. See [16] 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 is commonly
used during long welds.
WARNING
4-Step does not work during Spot Welding.
