WARNING
Smoke and gases!
Smoke and gases can lead to breathing difficulties and poisoning. In addition, solvent
vapour (chlorinated hydrocarbon) may be converted into poisonous phosgene due to
the ultraviolet radiation of the arc!
• Ensure that there is sufficient fresh air!
• Keep solvent vapour away from the arc beam field!
• Wear suitable breathing apparatus if appropriate!
Fire hazard!
Flames may arise as a result of the high temperatures, stray sparks, glowing-hot parts
and hot slag produced during the welding process.
Stray welding currents can also result in flames forming!
• Check for fire hazards in the working area!
• Do not carry any easily flammable objects such as matches or lighters.
• Keep appropriate fire extinguishing equipment to hand in the working area!
• Thoroughly remove any residue of flammable substances from the workpiece before
starting welding.
• Only continue work on welded workpieces once they have cooled down.
Do not allow to come into contact with flammable material!
• Connect welding leads correctly!
Risk of accidents due to non-compliance with the safety instructions!
Non-compliance with the safety instructions can be fatal!
• Carefully read the safety instructions in this manual!
• Observe the accident prevention regulations and any regional regulations!
• Inform persons in the working area that they must comply with the regulations!
Danger when coupling multiple power sources!
Coupling multiple power sources in parallel or in series has to be carried out by
qualified personnel and in accordance with the manufacturer's guidelines. Before
bringing the power sources into service for arc welding operations, a test has to verify
that they cannot exceed the maximum allowed open circuit voltage.
• Connection of the machine may be carried out by qualified personnel only!
• When decommissioning individual power sources, all mains and welding current leads have
to be safely disconnected from the welding system as a whole. (Danger due to inverse
voltages!)
• Do not couple welding machines with pole reversing switch (PWS series) or machines for
AC welding, as a minor error in operation can cause the welding voltages to be combined.
CAUTION
Noise exposure!
Noise exceeding 70 dBA can cause permanent hearing damage!
• Wear suitable ear protection!
• Persons located within the working area must wear suitable ear protection!

holders, remote controls, spare parts and replacement parts, etc.) from our range of
products!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
Damage to the machine due to stray welding currents!
Stray welding currents can destroy protective earth conductors, damage equipment and
electronic devices and cause overheating of components leading to fire.
• Make sure all welding leads are securely connected and check regularly.
• Always ensure a proper and secure electrical connection to the workpiece!
• Set up, attach or suspend all conductive power source components like casing, transport
vehicle and crane frames so they are insulated!
• Do not place any other electronic devices such as drillers or angle grinders, etc., on the
power source, transport vehicle or crane frames unless they are insulated!
• Always put welding torches and electrode holders on an insulated surface when they are
not in use!
Mains connection
Requirements for connection to the public mains network
High-performance machines can influence the mains quality by taking current from the mains
network. For some types of machines, connection restrictions or requirements relating to the
maximum possible line impedance or the necessary minimum supply capacity at the interface
with the public network (Point of Common Coupling, PCC) can therefore apply. In this respect,
attention is also drawn to the machines' technical data. In this case, it is the responsibility of
the operator, where necessary in consultation with the mains network operator, to ensure that
the machine can be connected.

Safety instructions
General
CAUTION
EMC Machine Classification
In accordance with IEC 60974-10, welding machines are grouped in two electromagnetic
compatibility classes - See 8 Technical data chapter:
Class A machines are not intended for use in residential areas where the power supply comes
from the low-voltage public mains network. When ensuring the electromagnetic compatibility of
class A machines, difficulties can arise in these areas due to interference not only in the supply
lines but also in the form of radiated interference.
Class B machines fulfil the EMC requirements in industrial as well as residential areas,
including residential areas connected to the low-voltage public mains network.
Setting up and operating
When operating arc welding systems, in some cases, electro-magnetic interference can occur
although all of the welding machines comply with the emission limits specified in the standard.
The user is responsible for any interference caused by welding.
In order to evaluate any possible problems with electromagnetic compatibility in the
surrounding area, the user must consider the following: (see also EN 60974-10 Appendix A)
• Mains, control, signal and telecommunication lines
• Radios and televisions
• Computers and other control systems
• Safety equipment
• The health of neighbouring persons, especially if they have a pacemaker or wear a hearing
aid
• Calibration and measuring equipment
• The immunity to interference of other equipment in the surrounding area
• The time of day at which the welding work must be carried out
Recommendations for reducing interference emission
• Mains connection, e.g. additional mains filter or shielding with a metal tube
• Maintenance of the arc welding equipment
• Welding leads should be as short as possible and run closely together along the ground
• Potential equalization
• Earthing of the workpiece. In cases where it is not possible to earth the workpiece directly,
it should be connected by means of suitable capacitors.
• Shielding from other equipment in the surrounding area or the entire welding system

WARNING
Risk of injury from electric shock!
Contact with live parts, e.g. welding current sockets, is potentially fatal!
• Follow safety instructions on the opening pages of the operating instructions.
• Commissioning may only be carried out by persons who have the relevant expertise of
working with arc welding machines!
• Connection and welding leads (e.g. electrode holder, welding torch, workpiece lead,
interfaces) may only be connected when the machine is switched off!
CAUTION
Insulate the arc welder from welding voltage!
Not all active parts of the welding current circuit can be shielded from direct contact. To
avoid any associated risks it is vital for the welder to adhere to the relevant safety
regulations. Even low voltages can cause a shock and lead to accidents.
• Wear dry and undamaged protective clothing (shoes with rubber soles/welder's gloves
made from leather without any studs or braces)!
• Avoid direct contact with non-insulated connection sockets or connectors!
• Always place torches and electrode holders on an insulated surface!
Risk of burns on the welding current connection!
If the welding current connections are not locked, connections and leads heat up and
can cause burns, if touched!
• Check the welding current connections every day and lock by turning in clockwise direction,
if necessary.
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.
CAUTION
Damage due to incorrect connection!
Accessory components and the power source itself can be damaged by incorrect
connection!
• Only insert and lock accessory components into the relevant connection socket when the
machine is switched off.
• Comprehensive descriptions can be found in the operating instructions for the relevant
accessory components.
• Accessory components are detected automatically after the power source is switched on.
Using protective dust caps!
Protective dust caps protect the connection sockets and therefore the machine against
dirt and damage.
• The protective dust cap must be fitted if there is no accessory component being operated
on that connection.
• The cap must be replaced if faulty or if lost!

Shielding gas supply (shielding gas cylinder for welding machine)
WARNING
Incorrect handling of shielding gas cylinders!
Incorrect handling of shielding gas cylinders can result in serious and even fatal injury.
• Observe the instructions from the gas manufacturer and in any relevant regulations
concerning the use of compressed air!
• Place shielding gas cylinders in the holders provided for them and secure with fixing
devices.
• Avoid heating the shielding gas cylinder!
CAUTION
Faults in the shielding gas supply.
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.
Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to
expel any dirt.

Setting the shielding gas quantity
CAUTION
Electric shocks!
When setting the shielding gas quantity, high voltage ignition pulses or open circuit
voltage are applied at the welding torch; these can lead to electric shocks and burning
on contact.
• Keep the welding torch electrically insulated from persons, animals or equipment during the
setting procedure.
•
Press the torch trigger and set the shielding gas quantity with the flow gauge of the pressure regulator.
Rule of thumb for the gas flow rate:
Diameter of gas nozzle in mm corresponds to gas flow in l/min.
Example: 7mm gas nozzle corresponds to 7l/min gas flow.
Incorrect shielding gas setting!
• 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!

Average value pulse welding
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.
Figure 5-10
AMP = Main current; e.g. 100 A
IPL = Pulse current = IP1 x AMP; e.g. 170% x 100 A = 170 A
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/FrE; e.g. 1/1 Hz = 1 s
bAL = Balance = bAL x Tpuls; e.g. 30% x 1 s = 0.3 s

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.
Automatic cut-out
The automatic cut-out function will be triggered by two conditions during the welding process:
• During the ignition phase (ignition fault) If there is no welding current within 3s after starting
the welding.
• During the welding phase (arc interruption) If the arc is interrupted for longer than 3s.
In both cases, the welding machine ends the ignition or welding process immediately.

Average value pulse welding
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.
Figure 5-22
AMP = Main current; e.g. 100 A
IPL = Pulse current = IP1 x AMP; e.g. 170% x 100 A = 170 A
IPP = Pulse pause current
Tpuls = Duration of one pulse cycle = 1/FrE; e.g. 1/1 Hz = 1 s
bAL = Balance = bAL x Tpuls; e.g. 30% x 1 s = 0.3 s

Voltage reducing device
The voltage reducing device is a requirement in some countries and in many internal company safety
guidelines for power sources.
The voltage reduction device is only active on VRD machine versions.
To increase safety, particularly in hazardous environments (like shipbuilding, pipe construction or mining),
the machine is equipped with the VRD (Voltage-reducing device) voltage reduction device.
The VRD signal light is illuminated, when the voltage reduction device is operating without fault and the
output voltage is reduced to a value specified in the relevant standard (see technical data).
