Introduction
General description
The system consists of a modern direct current generator
for the welding of metals, developed via application of the
inverter. This special technology allows for the
construction of compact light weight generators with high
performance. l’ts adjust ability, effeciency and energy
consumption make it an excellent work tool suitable for
coated electrode and GTAW (TIG) welding.

WARNING
The generator has an antisticking device that disables the
ower in case of output short circuit or sticking of the
electrode, thus allowing the electrode to easily detach
from the workpiece.
This device cuts in when the generator is powered, hence
also during the initial test period, therefore any inclusion of
load or short circuit in this period is seen as an anomaly
that causes disabling of output power (the message “ScA”
is displayed).
Welding SMAW (MMA) Process
INVERTEC®161S does not include the electrode holder
with lead necessary for SMAW welding, but the one can
be purchased separately.
Procedure of begin welding of SMAW process:
First turn the machine off.
Determine the electrode polarity for the electrode to be
used. Consult the electrode data for this information.
Depending on the polarity of using electrode, connect
the work lead and the electrode holder with lead to
output socket [13] or [14] and lock them. See the
Table 3.

Install the proper electrode in the electrode holder.
Turn the welding machine on.
Select SMAW welding mode [8].
Set the welding parameters.
The welding machine is now ready to weld.
By applying the principle of occupational health and
safety at welding, welding can be begun.
WARNING
Remote control connection. To use the remote control,
connect the remote control connector to the socket on the
front panel. In this condition the current can be adjusted
independently of the setting made on the generator.
The user can set functions:
The welding current
HOT START - value in percentage of nominal value
welding current during arc start current. The control is
used to set the level of the increased current and arc
start current is made easy.
ARC FORCE - the output current is temporarily
increased to clear short circuit connections between
the electrode and the workpiece. Lower values will
provide less short circuit current and a softer arc.
Higher settings will provide a higher short circuit
current, a more forceful arc and possibly more spatter.
Welding GTAW Process
INVERTEC®161S can be used to GTAW process with
DC (-). Arc ignition can be achieved only by lift TIG
method (contact ignition and lift ignition).
INVERTEC®161S does not include the torch to GTAW
welding, but the one can be purchased separately. See
"Accessories" chapter.
Procedure of begin welding of GTAW process:
First turn the machine off.
Connect GTAW torch to [13] output socket.
Connect the work lead to [14] output socket.
Connect the work lead to the welding piece with the
work clamp.
Install the proper tungsten electrode in the GTAW
torch.
Connect the gas pipe to the regulator on the gas
bottle.
Turn the machine on.
Select TIG LIFT welding mode [9].
Set the welding parameters [12].
Open the gas cock.
The welding machine is now ready to weld.
By applying the principle of occupational health and
safety at welding, welding can be begun.
GTAW welding with lift start indicator is carried out with
the following procedure:
ARC STRIKING: touch the
workpiece with the electrode to
cause short-circuiting between
the workpiece (2) and
electrode (1) then lift it to strike
the arc. The integrity of the
electrode tip is guaranteed by
a low striking current during the
short circuit between
workpiece and electrode.
Striking is always perfect even
at minimum welding current
setting and enables work to be
performed without polluting the
surrounding environment with
the very strong electromagnetic interference typically
caused by high frequency discharge. The advantages
can be summarized as follows:
1. Start without requiring high frequency.
2. Start without ruining the electrode tip at any current
setting, therefore there is no inclusion of tungsten
inside the workpiece (a phenomenon that occurs
with stroke start).
ARC EXTINGUISHING: To exit the welding phase the
operator can use the conventional lift method or,
alternatively, a new method that simulates the torch
button. This method, called “Fuzzy Exit" enables a
downslope without torch button to be obtained. During
the welding phase the operator only has to move away
from the workpiece to start a downslope. To interrupt
the slope (without waiting the time necessary for its
closing) the operator only has to lift the arc (like with
the classic Tig Lift procedure). Downslope duration
can be displayed and modified by pressing the key 11.
