4.1.1 Gas test – setting the shielding gas volume
• Slowly open the gas cylinder valve.
• Open the pressure regulator.
• Switch on the power source at the main switch.
• Set the relevant gas quantity for the application on the pressure regulator.
• The gas test can be activated at the machine control by pressing the "Gas test
" push-
button > see 3.1.1 chapter.
Setting the shielding gas quantity (gas test)
• Shielding gas flows for approx. 20 seconds or until the push-button is pressed again.
If the shielding gas setting is too low or too high, this can introduce air to the weld pool and may cause
pores to form. Adjust the shielding gas quantity to suit the welding task!

4.1.2 Welding task selection
The setting of the tungsten electrode diameter has a direct influence on the machine functionality, TIG
ignition behaviour and minimum current limits. The ignition energy is controlled by the set electrode
diameter. Smaller electrode diameters requires less ignition current and less ignition current time than
greater electrode diameters. The set value should correspond to the tungsten electrode diameter. The
value can also be set to meet individual requirements, e.g. for thin panels a smaller diameter is
recommended to reduce the ignition energy.
The following welding task is an example of use:

4.1.2.1 Recurring welding tasks (JOB 1–7)
The user has 7 more memory locations at their disposal to save recurring or different welding tasks on a
permanent basis. To do so, simply select the required memory location (JOB 1–7) and the welding task is
set as described previously.
Switching a JOB is only possible if no welding current flows. Up-slope and down-slope times can be set
individually for latched and non-latched operation.

4.1.3 Arc ignition
To change the ignition type, use parameter to switch between HF start ( ) and lift arc ( ) in the
Expert menu > see 4.1.9 chapter.
4.1.3.1 HF ignition
Figure 4-3
The arc is started without contact from high-voltage ignition pulses.
a) Position the welding torch in welding position over the workpiece (distance between the electrode tip
and workpiece should be approx. 2-3mm).
b) Press the torch trigger (high voltage ignition pulses ignite the arc).
c) Ignition current flows, and the welding process is continued depending on the operating mode
selected.
End the welding process: Release or press the torch trigger depending on the operating mode
selected.
4.1.3.2 Liftarc
Figure 4-4
The arc is ignited on contact with the workpiece:
a) Carefully place the torch gas nozzle and tungsten electrode tip onto the workpiece and press the torch
trigger (liftarc current flowing, regardless of the main current set).
b) Incline the torch over the torch gas nozzle to produce a gap of approx. 2-3 mm between the electrode
tip and the workpiece. The arc ignites and the welding current is increased, depending on the
operating mode set, to the ignition or main current set.
c) Lift off the torch and swivel to the normal position.
Ending the welding process: Release or press the torch trigger depending on the operating mode
selected.
4.1.3.3 Automatic cut-out
Once the fault periods have elapsed, the automatic cut-out stops the welding process when it has been
triggered by one of two states:
• During ignition
3 s after the start of the welding process, no welding current flows (ignition error).
• During welding
The arc is interrupted for more than 3 s (arc interruption).

When the foot-operated remote control is connected, the machine switches automatically to non-latched
operation. The up- and down-slopes are switched off.
A double-digit torch mode (11-x) needs to be set at the welding machine control to use the
alternative welding start (tapping start). The number of torch modes available depends on the
machine type.
4.1.4.4 spotArc
This process is suitable for tack welding or joint welding of metal sheets made from steel and CrNi alloys
up to a thickness of approximately 2.5 mm. Metal sheets of different thicknesses can also be welded on
top of one another. As this is a one-sided process, it is also possible to weld metal sheets onto tubular
sections such as round or square pipes. In arc spot welding, the arc melts through the upper metal sheet
and the lower metal sheet is melted onto it. This produces flat, fine-textured welding tacks which require
little or no post weld work, even in visible areas.

Sequence:
• Press torch trigger and hold down.
• The gas pre-flow time elapses.
• HF start pulses jump from the electrode to the workpiece. The arc ignites.
The welding current flows and immediately assumes the value of the ignition current
• HF switches off.
• The welding current ramps up to the main current
(AMP) within the set up-slope time .
The process ends when the set spotArc.time elapses or by releasing the torch trigger. With the spotArc
function enabled, the Automatic Puls pulse variant is activated as well. If required, the function can be
disabled by pressing the pulsed welding push-button.

4.1.4.5 spotmatic
In contrast to the spotArc operating mode, the arc is not ignited by pressing the torch trigger as is usual,
but by briefly touching the tungsten electrode against the workpiece. The torch trigger is used for welding
process activation. Activation is indicated by flashing of the spotArc/spotmatic signal light. The process
can be activated separately for each spot or also on a permanent basis. The setting is controlled using
the
process activation parameter in the configuration menu > see 4.6 chapter:
• Separate process activation (
> ):
The welding process has to be reactivated for every arc ignition by pressing the torch trigger. Process
activation is automatically terminated after 30 s of inactivity.
• Permanent process activation (
> ):
The welding process is activated by pressing the torch trigger once. The following arc ignitions are
initiated by shortly touching the tungsten electrode against the workpiece. Process activation is
terminated either by pressing the torch trigger again or automatically after 30 s of inactivity.
For spotmatic the separate process activation and the short spot time setting range are enabled by
default.
Ignition by touching the tungsten electrode against the workpiece can be disabled in the machine
configuration menu with parameter
. In this case the function works as with spotArc, but the spot time
setting range can be selected in the machine configuration menu.
The duration is set in the machine configuration menu using parameter

Up-slope and down-slope times possible for long spot time setting range (0.01–20.0 s) only.
Press and release torch trigger (tap) to activate the welding process.
Touch the torch gas nozzle and tungsten electrode tip carefully against the workpiece.
Incline the welding torch over the torch gas nozzle until there is a gap of approx. 2–3 mm between the
electrode tip and the workpiece. Shielding gas flows during the set gas pre-flow time
. The arc
ignites and the previously set ignition current
flows.
The main current phase
ends when the set spot time elapses.
For long-time spot welding only (parameter
= ):
The welding current decreases to the end-crater current
within the set down-slope time .
The gas post-flow time
elapses and the welding process ends.
Press and release the torch trigger (tap) to reactivate the welding process (only for separate
process activation). Touching the welding torch with the tungsten electrode tip against the
workpiece again will initiate the next welding processes.
4.1.5 TIG activArc welding
The EWM activArc process, thanks to the highly dynamic controller system, ensures that the power
supplied is kept virtually constant in the event of changes in the distance between the welding torch and
the weld pool, e.g. during manual welding. Voltage losses as a result of a shortening of the distance
between the torch and molten pool are compensated by a current rise (ampere per volt - A/V), and vice
versa. This helps prevents the tungsten electrode sticking in the molten pool and the tungsten inclusions
are reduced.

4.1.6 TIG antistick
The function prevents uncontrolled re-ignition following the sticking of the tungsten electrode in the weld
pool by switching off the welding current. In addition, wear at the tungsten electrode is reduced.
After triggering the function the machine immediately switches to the gas post-flow process phase. The
welder starts the new process again at the first cycle. The user can switch the function on or off
(parameter
) > see 4.6 chapter.

4.1.7 Pulse welding
The following pulse types can be selected:
• Automated pulsing
• Thermal pulsing
• Metallurgical pulsing
• Average value pulsing
4.1.7.1 Automated pulses
The automated pulsing pulse variant is only activated for DC welding in combination with the spotArc
operating mode. The current-dependent pulse frequency and balance create vibrations in the weld pool
that have a positive effect on the gap bridging. The required pulse parameters are automatically defined
by the machine control. If required, the function can be disabled by pressing the pulsed welding pushbutton.
Selection
Figure 4-14
4.1.7.2 Thermal pulsing
The operation sequences basically match the standard welding sequences, but there is an additional
switching back and forth between the main current AMP (pulse current) and the secondary current AMP%
(pulse pause current) at the set times. Pulse and pause times are entered at the control in seconds.

4.1.7.4 Average value pulse welding
A special feature with average value pulses is that the power source will always maintain the preset
average value. This makes this method especially suitable for welding according to welding procedure
specifications.
The parameter
must be switched to in the machine configuration menu to enable this pulse
variant. Once the function is activated, the red signal lights for the main current AMP and secondary
current AMP% light up at the same time.
Average value pulse welding means that the system switches between two currents periodically, an
average current value (AMP), a pulse current (Ipuls), a balance (
) and a frequency ( ) having been
defined first. The predefined ampere current average value is decisive, the pulse current (Ipuls) is defined
by the
parameter as a percentage of the average current value (AMP).
The pulse pause current (IPP) is not set; the machine control calculates the value instead to ensure that
the average value of the welding current (AMP) is maintained. For average value pulsing, the
current
is the secondary current only, activated with the torch trigger.
Figure 4-20
AMP = main current (average value), e.g. 100 A
Ipuls = pulse current =
x AMP, e.g. 140% x 100 A = 140 A
IPP = pulse pause current
Tpuls = duration of one pulse cycle = 1/
, e.g. 1/100 Hz = 10 ms
= balance
4.1.7.5 Metallurgical pulsing (kHz pulsing)
Metallurgical pulsing (kHz pulsing) uses the plasma force (arc force) occurring at high currents which
allows you to achieve a constricted arc with concentrated heat input. Unlike thermal pulsing, no times are
set; a frequency
and the balance are set instead. The pulsing process also occurs during the up-
slope and down-slope phase.

4.2.4 Average value pulse welding
With average value pulsing, two currents are periodically toggled. The user can adjust the welding current
(average current value AMP), pulse current Ipuls (parameter
), balance and frequency to the
welding task. The pulse pause current (IPP) is calculated by the machine control, so that the welding
current average value (AMP) is maintained and shown. This makes this method especially suitable for
welding according to welding procedure specifications.
Average value pulse welding means that two currents are switched periodically, a current average value
(AMP), a pulse current (Ipuls), a balance (
) and a frequency ( ) having been defined first. The
predefined ampere current average value is decisive, the pulse current (Ipuls) is defined by the
parameter as a percentage of the current average value (AMP). The pulse pause current (IPP) requires
no setting. This value is calculated by the machine control, so that the welding current average value
(AMP) is maintained at all times.

5.2 Dynamic power adjustment
This requires use of the appropriate mains fuse.
Observe mains fuse specification!
This function enables aligning the machine to the mains connection fusing to avoid continuous tripping of
the mains fuse. The maximum power input of the machine is limited by an exemplary value for the
existing mains fuse (several levels available).
You can predefine this value in the machine configuration menu using parameter
. The function
automatically adjusts the welding power to an uncritical level for the mains fuse.
