Depending on the welding process, a minimum level of equipment is required to work with the welding system.
The following describes the welding processes and the corresponding minimum equipment for welding operations.

The welding machine is generator-compatible.

The maximum apparent power S_1max of the welding machine must be known in order to select the correct generator output.
The maximum apparent power S_1max of the welding machine is calculated as follows:

Three-phase devices: S_1max = I_1max x U₁ x √3

Single-phase devices: S_1max = I_1max x U₁

I_1max and U₁ according to the device rating plate and technical data

The generator apparent power S_GEN needed is calculated using the following rule of thumb:

S_GEN = S_1max x 1.35

A smaller generator can be used when not welding at full power.

IMPORTANT! The generator apparent power S_GEN must not be less than the maximum apparent power S_1max of the welding machine!

When single-phase devices are being operated with a three-phase generator, note that the stated apparent power of the generator is often just the total that can be present across all three phases of the generator. If necessary, obtain further information about the single-phase power of the generator from the generator manufacturer.

IMPORTANT! Ensure secure grounding of the mains connection.

Due to local regulations and national guidelines, a residual-current circuit breaker may be required when connecting a device to the public grid. The residual-current circuit breaker recommended for the device can be found in the technical data.

In the case of /nc and /XT welding machines, no mains cable is connected when delivered.
Before commissioning, a mains cable corresponding to the connection voltage must be installed with a minimum cross-section according to the following table.

In the case of /nc and /XT welding machines, no mains cable is connected when delivered.
Before commissioning, a mains cable corresponding to the connection voltage must be installed with a minimum cross-section according to the following table.

If a welding machine is delivered without a mains cable installed, a mains cable corresponding to the welding machine's connection voltage must be connected before commissioning.

IMPORTANT! The ground conductor should be approx. 20-25 mm (0.8-1 in.) longer than the phase conductors.

The device can be set up and operated outdoors in accordance with protection class IP23. Direct moisture (e.g., from rain) must be avoided.

Electromagnetic compatibility (EMC) describes the unwanted mutual influence of electrical/electronic devices.

The EMC device classification is shown on the rating plate of the device or in the technical data.

Despite compliance with the standardized emission limit values, electrical devices can, in certain cases, influence each other in the intended application area.

The device produces a maximum noise level of <80 dB(A) (ref. 1pW) when idling and in the cooling phase following operation in relation to the maximum permitted operating point at standard loading in accordance with EN 60974-1.

A workplace-specific emission value for welding (and cutting) cannot be specified because this value depends on the welding process and the environmental conditions. It is influenced by a wide range of parameters, such as the welding process itself (MIG/MAG, TIG welding), the selected current type (direct current, alternating current), the power range, the type of weld metal, the resonance properties of the workpiece, the workplace environment, and many other factors.

Commissioning of the welding system is described in relation to a standard configuration for the main usage scenario of TIG welding.

The standard configuration consists of the following system components:

IMPORTANT! For optimum welding results, determine the welding circuit resistance “r" before starting welding.

The welding circuit resistance "r" must also be determined if one of the following components of the welding system is changed:

For more information on determining the welding circuit resistance, refer to the 2nd TIG menu (see page(→)).

For the Artis 300 DC /W water-cooled welding machines, a 5 l canister containing coolant is included in the scope of supply.

If the tungsten electrode is overloaded, the "electrode overloaded" indicator illuminates on the control panel.
See also page (→), item (5)

Possible causes of an overloaded tungsten electrode:

Remedy:

IMPORTANT! The "electrode overloaded" indicator is tailored for use with ceriated tungsten electrodes. For all other electrodes, the "electrode overloaded" indicator can be used as a guide.

It is also possible to end welding with the TIG Comfort Stop (CSS) function on welding torches with or without a torch trigger.
This function can be adjusted in the TIG - 2nd level Setup menu (see page (→)).

If the arc breaks and no current flow takes place during the time set in the Setup menu, the welding system automatically switches off. The control panel displays the service code "no | Arc".

Press any button on the control panel or the torch trigger to restart the welding process.

The "2nd level Setup menu" section describes how to set the arc break monitoring (Arc) setup parameters.

The welding system has an Ignition Time-Out.

If the torch trigger is pressed, gas pre-flow begins immediately and the ignition procedure is then initiated. If no arc emerges during the period of time set in the Setup menu, the welding system automatically switches off. The control panel displays the service code "no | IGn".

Press any button on the control panel or the torch trigger to launch a further attempt.

The "2nd level Setup menu" section describes how to set the "Ignition Time-Out" (Ito) parameter.

The welding current set at the start of welding may not always be optimum for the entire welding process:

The TIG pulsing function is able to help with this (TIG welding with a pulsing welding current):
A low base current I-G rises steeply to a significantly higher pulse current I1 and falls again, after the set time dcY (duty cycle), to the base current I-G.
During TIG pulsing, small sections of the welding location melt quickly and then rapidly re-solidify.
During manual applications, the welding wire is applied in the maximum current phase during TIG pulsing (only possible in the low frequency range from 0.25-5 Hz). Higher pulse frequencies are mostly used in automated applications and mainly serve to stabilize the arc.

TIG pulsing is used to weld steel pipes when welding out-of-position or to weld thin sheet metal.

TIG pulsing in operation:

There is a tacking function on the welding machine.

When a period of time is set for the "tAC" (tacking) setup parameter, the tacking function is assigned to the 2-step and 4-step modes. The process of the operating modes remains unchanged.
During this time, a pulsed welding current is available, which optimizes the merging of the weld pool when tacking two components.

Tacking function in operation:

Key:

IMPORTANT! When using a pulsed welding current:

The pulsed welding current starts

Depending on the set tAC time, the pulsed welding current can be stopped up to and including the final-current phase I_E ("tAC" setup parameter to "On").

After the tAC time has elapsed, further welding is carried out at a constant welding current. Set pulse parameters are available if applicable.

IMPORTANT! To set a defined tacking time, the "tAC" setup parameter can be combined with the "SPt" setup parameter (spot welding time).

All indicators on the control panel briefly illuminate.

The setting of the available parameters is described in the "Setup menu" section from page (→).

A starting current of < 100% (SoftStart) is suitable for basic electrodes. Ignition is carried out with a low welding current. As soon as the arc is stable, the welding current continues to increase until it reaches the welding current command value that was set.

Example of a starting current < 100% (SoftStart)

Advantages:

• Improvement of ignition properties with electrodes that ignite at a low welding current
• Slag inclusions largely avoided
• Reduction of welding spatter

The starting current and starting current time are set in the Setup menu from page (→).

As the arc becomes shorter, the welding voltage may also fall so that the stick electrode is more likely to stick to the workpiece. This may also cause the stick electrode to burn out.

Electrode burn-out is prevented by activating the anti-stick function. If the stick electrode begins to stick, the welding system immediately switches the welding current off. The welding process can be resumed without problems once the stick electrode has been detached from the workpiece.

The anti-stick function can be activated or deactivated in the Setup menu, see page (→).

off / tHF / EHF / on
Factory setting: on

off
No HF ignition at the start of welding—welding started by contact ignition

tHF
The welding process is initiated by briefly touching the workpiece with the tungsten electrode. The high frequency ignition is performed after the set HF ignition delay time has elapsed.

EHF
Start with an external ignition device, e.g., plasma welding

on
HF ignition is activated

The HF ignition special indicator illuminates on the control panel when the "HF ignition" parameter is set to "on".

HF ignition delay time
Time after touching the workpiece with the tungsten electrode after which the high-frequency ignition takes place.

0.1-5.0 s
Factory setting: 0.1 s

Pulse TAC display
off / on
Factory setting: on

This menu item can be used to hide the pulsing and tacking parameters on the control panel in the welding parameter overview.

Ignition time out
Period of time until the safety cut-out following failed ignition

0.1-9.9 s
Factory setting: 5 s

Arc break monitoring
Period of time until the safety cut-out following an arc break

0.1-9.9 s
Factory setting: 1.0 s

IMPORTANT! Arc break monitoring is a safety function and cannot be deactivated.
A description of the arc break monitoring function can be found in the "TIG welding" section on page (→).

TIG Comfort Stop Sensibility—comfort stop sensitivity
The parameter is only available if the "Trigger" parameter is set to "off".

oFF / 0.6-3.5 V
Factory setting: 1.5 V

At the end of the welding process, an automatic shutdown of the welding current follows a significant increase of the arc length. This prevents the arc from having to be unnecessarily lengthened when lifting the TIG welding torch.

Process:

Break voltage
For setting a voltage value at which the welding process may be ended by slightly raising the TIG welding torch.
The higher the break voltage value, the higher the arc can be raised.

The break voltage values for 2-step mode, 4-step mode, and operation with a foot-operated remote control are all stored together.
If the "tri" parameter (trigger—torch trigger operating mode) is set to "oFF", the values are stored separately.

10-45 V
Factory setting: 35 V (for 2-step and 4-step mode and operation with a foot-operated remote control)
Factory setting: 25 V (for trigger = oFF operation)

Main current changeover
on / off
Factory setting: on

on
After welding has started, an automatic selection of the main current I₁ takes place.
The main current I₁ can be adjusted immediately.

off
During welding, the last selected parameter remains selected.
The last selected parameter can be adjusted immediately.
No automatic selection of the main current I₁ takes place.

The following parameters are available through the second level of the Setup menu:

System active time
For displaying the welding duration (the time during which welding has taken place)

The complete welding duration is divided across several displays and can be viewed by turning the selection dial.
Displayed in h / min. / sec.

System on time
For displaying the operating duration (count begins as soon as the device is switched on)

The complete operating duration is divided across several displays and can be viewed by turning the selection dial.
Displayed in h / min. / sec.

Fuse
For displaying / setting the fuse being used on XT devices

At 230 V: 10, 13, 16 A / off

Factory setting:
off

If a fuse is set on the welding machine, the welding machine will limit the current drawn from the grid. This prevents an immediate tripping of the automatic circuit breaker.

Max. welding current depending on the selected fuse
Duty cycle = 40%

Standard devices EU 3 x 400 V +/- 10%
/nc 3 x 400 V +/-10%
/XT 3 x 200 V-575V +/-10%

Canada 3 x 575 V +/-10%

Software version
The complete version number of the current software is divided across several displays and can be viewed by turning the selection dial.

Automatic shutdown
off / 5-60 minutes
Factory setting: off

If the device is not used or operated within a set period of time, it automatically switches into Standby mode.
Pressing a button on the control panel switches off Standby mode—the device is now ready for welding.

Cooling unit operating mode
For controlling a cooling unit
auto / off
Factory setting: auto

auto:
When welding starts, the cooling unit begins to work (fan and coolant pump run). After the end of welding, the cooling unit continues to operate for 2 minutes. When the 2 minutes have elapsed, the cooling unit also switches off.

off
No operation, even when welding starts

The maximum run-on time is 2 minutes.

Filter flow sensor time
For setting the time between the flow sensor tripping and the output of a warning message
5-25 s
Factory setting: 10 s

The following parameters are available through the stick electrode Setup menu:

HotStart current
1-200%
Factory setting: 130%

Starting current duration
0.1-2.0 s
Factory setting: 0.5 s

Start ramp
For activating / deactivating the start ramp for the manual metal arc welding ignition process

on / off
Factory setting: on (activated)

Pulse frequency
For pulse welding with stick electrodes

off / 0.2-990 Hz
Factory setting: off

The pulsing special indicator lights up on the control panel if a value for the pulse frequency has been entered.

Anti-stick
on / off
Factory setting: on

As the arc becomes shorter, the welding voltage may also fall so that the stick electrode is more likely to stick to the workpiece. This may also cause the stick electrode to burn out.

Electrode burn-out is prevented by activating the anti-stick function. If the stick electrode begins to stick, the welding machine immediately switches the welding current off. The welding process can be resumed without problems once the stick electrode has been detached from the workpiece.

Dynamic correction
For optimizing the welding result

0-100
Factory setting: 20

0
Softer and low-spatter arc

100
Harder and more stable arc

At the moment of droplet transfer or in event of a short circuit, a short-term increase in the amperage will occur. To maintain a stable arc, the welding current temporarily rises. If the stick electrode is at risk of sinking into the weld pool, this action prevents the weld pool from solidifying, as well as reducing the duration of the arc's short circuit. The risk of the stick electrode sticking is largely ruled out as a result.

Break voltage
Limitation of the welding voltage

25-90 V
Factory setting: 45 V

In principle, the arc length depends on the welding voltage. To end the welding process, a significant lifting of the stick electrode is usually required. The "Uco" parameter allows the welding voltage to be limited to a value, which permits the welding process to be ended by only slightly lifting the stick electrode.

IMPORTANT! If the welding process regularly comes to an unintentional end, set the break voltage parameter to a higher value.

Reset welding system
No / YES / ALL
Factory setting: No

YES:
Only the currently active welding mode is reset (2T / 4T / trigger = oFF / STICK / STICK CEL / foot-operated remote control)

ALL:
All operating modes are reset.
