Design and function
Observe documentation of other system components when connecting!
5.1
General
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!
The cooling modules (pump and fan) are controlled solely by the welding machine.
If there is a shortage of coolant, this will be detected and displayed automatically
by the welding machine (see the operating instructions for the welding unit).
• The cooling units receive their power from the relevant welding machines.
• The coolant pump is protected against overloading by an overcurrent release.
• Self-closing rapid-action closure couplings are used for the coolant connections.
• In the event of insufficient coolant pressure or coolant throughput, the welding machine is shut down
to prevent damage to the welding torch.
• The cooling modules are fitted with an air-cooled heat exchanger. This means that the cooling output
depends on the ambient temperature. The lower the ambient temperature and therefore the air intake
temperature, the higher the cooling output.
5.2
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!
5.3
Installation
WARNING
Risk of accident due to improper transport of machines that may not be l ifted!
Do not lift or suspend the machine! The machine can fall down and cause injuries! The
handles and brackets are suitable for transport by hand only!
• The machine may not be lifted by crane or suspended!
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.
