WARNING
Risk of injury from electrical voltage!
Contact with live parts, e.g. power connections, can be fatal!
• Observe the safety information on the first pages of the operating instructions!
• Commissioning must be carried out by persons who are specifically trained in handling
power sources!
• Connect connection or power cables while the machine is switched off!
CAUTION
Risk from electrical current!
If welding is carried out alternately using different methods and if a welding torch and
an electrode holder remain connected to the machine, the open-circuit/welding voltage
is applied simultaneously on all cables.
• The torch and the electrode holder should therefore always be placed on an insulated
surface before starting work and during breaks.
Read and observe the documentation to all system and accessory components!

Use of unsuitable coolants results in damage to the welding torch!
Unsuitable coolants can cause damage to the welding torch!
• Use only KF 23E coolants (observe temperature range of - 10 °C bis + 40°C).
Coolant mixtures!
Mixtures with other liquids or the use of unsuitable coolants result in material damage and
renders the manufacturer's warranty void!
• Only use the coolant described in this manual (overview of coolants).
• Do not mix different coolants.
• When changing the coolant, the entire volume of liquid must be changed.
Dispose of the coolant in accordance with local regulations and the material safety data sheets
(German waste code number: 70104).
May not be disposed of in household waste.
Prevent entry into sewers.
Absorb with liquid-binding material (sand, gravel, acid-binding agents, universal binding agents,
sawdust).
5.1 Welding torch cooling system
Figure 5-1
Part of the heat is transferred via the plasma nozzle and gas lens to the torch cooling system (1), another
part is blown (3) from the torch by the shielding gas (2).
The large contact area of the electrode offers several advantages:
• Optimum cooling
• Optimum flow transfer
• Long electrode service life

5.2 Commissioning
5.2.1 Preparations
Let the plasma gas flow through the torch for several minutes so as to purge it from any air humidity and
5.2.2 Start of welding
5.2.3 Setting the electrode
5.2.4 Selecting the nozzle
avoid ignition problems.
Before starting to weld, the arc has to briefly stabilise.
At this stage, the burning pilot arc is not centred.
When starting a new welding task, the electrode has to be re-set.
Turn the collet casing adjusting ring to optimally set the arc.
You can transfer the electrode position to the electrode gauge to keep using it for the same task.
To ensure an optimum service life of the nozzles, don’t operate the nozzle above the maximum current.
If necessary, switch to a nozzle of the next size.
The nozzle service life is also affected by the plasma gas quantity used.
The following applies: The lower the plasma gas quantity, the shorter the service life.
As a reference, take the nozzle diameter (same value or multiplied by factor 1.5) as distance between
plasma nozzle and workpiece.
Figure 5-2
Design and function
Welding parameters
099-002025-EW501

When the current load is too high or the torch held at too steep an angle, the nozzle service life
will decrease significantly.
5.2.5 Double arc
When the current load is too high or the torch held at too steep an angle, a second arc will form between
workpiece and plasma nozzle.
5.2.6 Grinding the electrode
The electrodes for plasma welding should be grinded mechanically. This will increase the electrode
service life and the welding result will become reproducible.
The grinding angle for cathode welding is 30° (setting angle 15°).
The anode electrode, whose tip is balled or semispherical during operation, is pre-grinded with a bevel of
about 1 mm and at a bevel angle of 45°. It will develop its final form for welding after brief loading in the
higher current range (approx. 35 A)
The regrinding lengths depend on the maximum current load.
The following applies: The lower the actual current load during operation, the more frequently you can
regrind an electrode.

WARNING
Risk of injury due to improper handling of shielding gas cylinders!
Improper handling and insufficient securing of shielding gas cylinders can cause
serious injuries!
• Observe the instructions from the gas manufacturer and any relevant regulations
concerning the use of compressed air!
• Do not attach any element to the shielding gas cylinder valve!
• Prevent the shielding gas cylinder from heating up.
An unhindered shielding gas supply from the shielding gas cylinder to the welding torch is a
fundamental requirement for optimum welding results. In addition, a blocked shielding gas
supply may result in the welding torch being destroyed.
• Always re-fit the yellow protective cap when not using the shielding gas connection.
• All shielding gas connections must be gas tight.

• In the event that the provisions of one of the below-stated tests are not met, the machine
must not be operated again until it has been repaired and a new test has been carried out!
6 Maintenance, care and disposal
6.1 General
Repair and maintenance work may only be performed by qualified authorised personnel; otherwise the
right to claim under warranty is void. In all service matters, always consult the dealer who supplied the
machine. Return deliveries of defective equipment subject to warranty may only be made through your
dealer. When replacing parts, use only original spare parts. When ordering spare parts, please quote the
machine type, serial number and item number of the machine, as well as the type designation and item
number of the spare part.
Under the specified ambient conditions and normal working conditions this machine is essentially
maintenance-free and requires just a minimum of care.
Contamination of the machine may impair service life and duty cycle. The cleaning intervals depend on
the ambient conditions and the resulting contamination of the machine. The minimum interval is every six
months.
6.2 Cleaning
• Clean the outer surfaces with a moist cloth (no aggressive cleaning agents).
• Purge the machine venting channel and cooling fins (if present) with oil- and water-free compressed
air. Compressed air may overspeed and destroy the machine fans. Never direct the compressed air
directly at the machine fans. Mechanically block the fans, if required.
• Check the coolant for contaminants and replace, if necessary.
6.2.1 Dirt filter
The duty cycle of the welding machine decreases as an effect of the reduced cooling air volume.
Depending on the amount of dirt building up (at least every two months), the dirt filter has to be
uninstalled and cleaned regularly (e.g. by purging with compressed air).
