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!
5.1 Transport and installation
WARNING
Risk of accident due to improper transport of machines that must not be lifted!
Do not lift or suspend the machine! The machine can drop and cause injuries! The
handles, straps or brackets are suitable for transport by hand only!
•The machine must not be suspended or lifted using a crane.

5.1.2 Ambient conditions
T he machine must not be operated in the open air and must only be set up and operated on a
suitable, stable and level base!
•The operator must ensure that the ground is non-slip and level, and provide sufficient lighting
for the place of work.
•Safe operation of the machine must be guaranteed at all times.
Unusually high quantities of dust, acid, corrosive gases or substances may damage the
equipment.
•Avoid high volumes of smoke, vapour, oil vapour and grinding dust!
•Avoid ambient air containing salt (sea air)!

Storage in an enclosed space, temperature range of the ambient air:
•-30 °C to +70 °C
Relative air humidity
•Up to 90% at 20 °C
5.1.3 Machine cooling
Insufficient ventilation results in a reduction in performance and equipment damage.
•Observe the ambient conditions!
•Keep the cooling air inlet and outlet clear!
•Observe the minimum distance of 0.5 m from obstacles!
5.1.4 Workpiece lead, general
CAUTION
Risk of burning due to incorrect welding current connection!
If the welding current plugs (machine connections) are not locked or if the workpiece
connection is contaminated (paint, corrosion), these connections and leads can heat up
and cause burns when touched!
•Check welding current connections on a daily basis and lock by turning to the right when
necessary.
•Clean workpiece connection thoroughly and secure properly. Do not use structural parts of
the workpiece as welding current return lead!

5.1.5 Notes on the installation of welding current leads
Incorrectly installed welding current leads can cause faults in the arc (flickering).
Lay the workpiece lead and hose package of power sources without HF igniter (MIG/MAG) for as
long and as close as possible in parallel.
Lay the workpiece lead and hose package of power sources with HF igniter (TIG) for as long as
possible in parallel with a distance of 20 cm to avoid HF sparkover.
Always keep a distance of at least 20 cm to leads of other power sources to avoid interferences
Always keep leads as short as possible! For optimum welding results max. 30 m (welding lead +
intermediate hose package + torch lead).
Figure 5-2
Use an individual welding lead to the workpiece for each welding machine!
Figure 5-3
Fully unroll welding current leads, torch hose packages and intermediate hose packages. Avoid
loops!
Always keep leads as short as possible!
Lay any excess cable lengths in meanders.

5.1.5.1 Stray welding currents
WARNING
Risk of injury due to stray welding currents!
Stray welding currents can destroy protective earth conductors, damage machines and
electronic devices and cause overheating of components, leading to fire.
•Check that all welding current connections are firmly secured and electrical connections are
in perfect condition.
•Set up, attach or suspend all conductive power source components such as casing,
transport vehicles and crane frames so they are insulated.
•Do not place any other electronic devices such as drills or angle grinders 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.

DANGER
Hazards caused by improper mains connection!
An improper mains connection can cause injuries or damage property!
•Only operate machine using a socket that has correctly fitted protective earth.
•The mains voltage indicated on the rating plate must match the supply voltage.
•If a new mains plug must be fitted, only an electrician may do so as per the relevant
national legislation or regulations.
•Mains plug, socket and lead must be checked by an electrician on a regular basis.
•When operating the generator, always ensure it is earthed as stipulated in the operating
instructions. The network created must be suitable for operating machines according to
protection class I.
5.1.7.1 Mains configuration
The machine may only be connected to a one-phase system with two conductors and an earthed
neutral conductor.

5.1.8 Welding torch cooling system
Insufficient frost protection in the welding torch coolant!
Depending on the ambient conditions, different liquids are used for cooling the welding
torch > see 5.1.8.1 chapter.
Coolants with frost protection (KF 37E or KF 23E) must be checked regularly to ensure that the
frost protection is adequate to prevent damage to the machine or the accessory components.
•The coolant must be checked for adequate frost protection with the TYP 1 frost protection
tester .
•Replace coolant as necessary if frost protection is inadequate!
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).
