Gas Connection
Shield gas is required for welding GMAW and GTAW
process. Gas flow regulator and gas hoses have been
added to
SPEEDTEC 215C . 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 bracket, but
the height of gas cylinder doesn’t have to be higher than
43in/1,1m. To install E size gas cylinder (230mm) on the
machine, please install bracket from position 21 using
four screws added to SPEEDTEC 215C packaging
(Figure 7.). The gas cylinder which is placed on the
bracket has to be secured by two chains.

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 includes the gun necessary
for GMAW or FCAW-SS welding.
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.
The Burnback Time is the amount of time that the weld
output continues after the wire stops feeding. It prevents
the wire from sticking in the puddle and prepares the end
of the wire for the next arc start.
Run-in WFS sets the wire feed speed from the time the
trigger is pulled until an arc is established.
